Journal-ref: Int. J. Mod. Phys. D14 (2005) 687-695
We present analytic solutions of Maxwell equations for infinitely long
cylindrical conductors with nonvanishing electric charge and currents in the
external background spacetime of a line gravitomagnetic monopole. It has been
shown that vertical magnetic field arising around cylindrical conducting shell
carrying azimuthal current will be modified by the gravitational field of NUT
source. We obtain that the purely general relativistic magnetic field which has
no any Newtonian analog will be produced around charged gravitomagnetic
monopole.

Title: Perfect magnetohydrodynamics as a field theory
Authors:
Jacob D. Bekenstein,
Gerold Betschart
Comments: 15 pages, LaTeX, no figures
Subj-class: General Relativity and Quantum Cosmology; Plasma Physics
We propose the generally covariant action for the theory of a self-coupled
complex scalar field and electromagnetism which by virtue of constraints is
equivalent, in the regime of long wavelengths, to perfect magnetohydrodynamics
(MHD). We recover from it the Euler equation with Lorentz force, and the
thermodynamic relations for a prefect fluid. The equation of state of the
latter is related to the scalar field's self potential. We introduce 1+3
notation to elucidate the relation between MHD and field variables. In our
approach the requirement that the scalar field be single valued leads to the
quantization of a certain circulation in steps of \hbar; this feature leads, in
the classical limit, to the conservation of that circulation. The circulation
is identical to that in Oron's generalization of Kelvin's circulation theorem
to perfect MHD; we here characterize the new conserved helicity associated with
it. We also demonstrate the existence for MHD of two Bernoulli-like theorems
for each spacetime symmetry of the flow and geometry; one of these is pertinent
to suitably defined potential flow. We exhibit the conserved quantities
explicitly in the case that two symmetries are simultaneously present, and give
examples. Also in this case we exhibit a new conserved MHD circulation distinct
from Oron's, and provide an example.

Title: Measuring coalescing massive binary black holes with gravitational
waves: The impact of spin-induced precession
Authors:
Ryan N. Lang,
Scott A. Hughes
Comments: 22 pages, 10 figures
The coalescence of massive black holes generates gravitational waves (GWs)
that will be measurable by space-based detectors such as LISA to large
redshifts. The spins of a binary's black holes have an important impact on its
waveform. Specifically, geodetic and gravitomagnetic effects cause the spins to
precess; this precession then modulates the waveform, adding periodic structure
which encodes useful information about the binary's members. Following
pioneering work by Vecchio, we examine the impact upon GW measurements of
including these precession-induced modulations in the waveform model. We find
that the additional periodicity due to spin precession breaks degeneracies
among certain parameters, greatly improving the accuracy with which they may be
measured. In particular, mass measurements are improved tremendously, by one to
several orders of magnitude. Localization of the source on the sky is also
improved, though not as much -- low redshift systems can be localized to an
ellipse which is roughly $10- {a few} \times 10$ arcminutes in the long
direction and a factor of 2 -- 5 smaller in the short direction. Though not a
drastic improvement relative to analyses which neglect spin precession, even
modest gains in source localization will greatly facilitate searches for
electromagnetic counterparts to GW events. Determination of distance to the
source is likewise improved: We find that relative error in measured luminosity
distance is commonly $\sim 0.1-0.4%$ at $z \sim 1$. Finally, with the inclusion
of precession, we find that the magnitude of the spins themselves can typically
be determined for low redshift systems with an accuracy of about $0.1-10 %$,
depending on the spin value, allowing accurate surveys of mass and spin
evolution over cosmic time.

Title: Limits on Neutron Lorentz Violation from Pulsar Timing
Authors:
B. Altschul
Comments: 9 pages
Pulsars are the most accurate naturally occurring clocks, and data about them
can be used to set bounds on neutron-sector Lorentz violations. If SO(3)
rotation symmetry is completely broken for neutrons, then pulsars' rotation
speeds will vary periodically. Pulsar timing data limits the relevant
Lorentz-violating coefficients to be smaller than 1.7 x 10^(-8) at at least 90%
confidence.

Title: Baryogenesis, Dark Matter and the Pentagon
Authors:

Comments: JHEP3 LaTeX, 14 pages
We present a new mechanism for baryogenesis, which links the baryon asymmetry
of the universe to the dark matter density. The mechanism arises naturally in
the Pentagon model of TeV scale physics. In that context, it forces a
re-evaluation of some of the assumptions of the model, and we detail the
changes that are required in order to fit observations.

Title: A non-perturbative study of 4d U(1) non-commutative gauge theory -- the
fate of one-loop instability
Authors:
Wolfgang Bietenholz,
Jun Nishimura,
Yoshiaki Susaki,
Jan Volkholz
Comments: 29 pages, 23 figures
Recent perturbative studies show that in 4d non-commutative spaces, the
trivial (classically stable) vacuum of gauge theories becomes unstable at the
quantum level, unless one introduces sufficiently many fermionic degrees of
freedom. This is due to a negative IR-singular term in the one-loop effective
potential, which appears as a result of the UV/IR mixing. We study such a
system non-perturbatively in the case of pure U(1) gauge theory in four
dimensions, where two directions are non-commutative. Monte Carlo simulations
are performed after mapping the regularized theory onto a U(N) lattice gauge
theory in d=2. At intermediate coupling strength, we find a phase in which open
Wilson lines acquire non-zero vacuum expectation values, which implies the
spontaneous breakdown of translational invariance. In this phase, various
physical quantities obey clear scaling behaviors in the continuum limit with a
fixed non-commutativity parameter $\theta$, which provides evidence for a
possible continuum theory. The extent of the dynamically generated space in the
non-commutative directions becomes finite in the above limit, and its
dependence on $\theta$ is evaluated explicitly. We also study the dispersion
relation. In the weak coupling symmetric phase, it involves a negative
IR-singular term, which is responsible for the observed phase transition. In
the broken phase, it reveals the existence of the Nambu-Goldstone mode
associated with the spontaneous symmetry breaking.

The general relativistic kinetic theory including the effect of a stationary
gravitational field is applied to the electromagnetic transport processes in
conductors. Then it is applied to derive the general relativistic Ohm's law
where the gravitomagnetic terms are incorporated. The total electric charge
quantity and charge distribution inside conductors carrying conduction current
in some relativistic cases are considered. The general relativistic Ohm's law
is applied to predict new gravitomagnetic and gyroscopic effects which can, in
principle, be used to detect the Lense-Thirring and rotational fields.

Title: Is Brane Inflation Eternal?
Authors:
Xingang Chen,
Sash Sarangi,
S.-H. Henry Tye,
Jiajun Xu
Comments: 31 pages
In this paper, we show that eternal inflation of the random walk type is
generically absent in the brane inflationary scenario. Depending on how the
brane inflationary universe originated, eternal inflation of the false vacuum
type is still quite possible. Since the inflaton is the position of the
D3-brane relative to the anti-D3-brane inside the compactified bulk with finite
size, its value is bounded. In DBI inflation, the warped space also restricts
the amplitude of the scalar fluctuation. These upper bounds impose strong
constraints on the possibility of eternal inflation. We find that eternal
inflation due to the random walk of the inflaton field is absent in both the
KKLMMT slow roll scenario and the DBI scenario. A more careful analysis for the
slow-roll case is also presented using the Langevin equation, which gives very
similar results. We discuss possible ways to obtain eternal inflation of the
random walk type in brane inflation. In the multi-throat brane inflationary
scenario, the branes may be generated by quantum tunneling and roll out the
throat. Eternal inflation of the false vacuum type inevitably happens in this
scenario due to the tunneling process. Since these scenarios have different
cosmological predictions, more data from the cosmic microwave background
radiation will hopefully select the specific scenario our universe has gone
through.

Title: On a recently proposed metric linear extension of general relativity to
explain the Pioneer anomaly
Authors:
Lorenzo Iorio
Comments: LaTex2e, 10 pages, no figures, no tables, 14 references
Recently, Jaekel and Reynaud proposed a gravitational mechanism for the
Pioneer anomaly based on a metric linear extension of general relativity which
would be able to explain the anomalous acceleration experienced by the Pioneer
spacecraft without contradicting either the equivalence principle or what we
know about the planetary motions. In this paper we perform an independent test
of such an hypothesis by showing that the planets' orbits are, in fact,
affected by the suggested mechanism as well and comparing the resulting effects
with the latest observational determinations. It turns out that the predicted
perihelion precessions, expressed in terms of an adjustable free parameter
zeta_P set equal to the value used to reproduce the magnitude of the Pioneer
anomalous acceleration, are quite different from the observationally determined
extra-advances of such Keplerian element for the inner planets. Conversely, the
values obtained for zeta_P from the determined perihelion extra-rates of the
inner planets turn out to be in disagreement with the value which would be
required to accommodate the Pioneer anomaly. As a consequence, the suggested
explanation of gravitational origin for the Pioneer anomaly, based on the
assumption that zeta_P is constant throughout the Solar System, must be
rejected.

Title: Effects of Cosmic Strings on Free Streaming
Authors:
Tomo Takahashi,
Masahide Yamaguchi
Comments: 14 pages, 9 figures
We study the effect of free streaming in a universe with cosmic strings with
time-varying tension as well as with constant tension. Although current
cosmological observations suggest that fluctuation seeded by cosmic strings
cannot be the primary source of cosmic density fluctuation, some contributions
from them are still allowed. Since cosmic strings actively produce isocurvature
fluctuation, the damping of small scale structure via free streaming by dark
matter particles with large velocity dispersion at the epoch of
radiation-matter equality is less efficient than that in models with
conventional adiabatic fluctuation. We discuss its implications to the
constraints on the properties of particles such as massive neutrinos and warm
dark matter.

Title: Generalized dilaton-Maxwell cosmic string and wall solutions
Authors:
John Morris
Comments: 11 pages; to appear in Phys.Lett.B
The class of static solutions found by Gibbons and Wells for
dilaton-electrodynamics in flat spacetime, which describe nontopological
strings and walls that trap magnetic flux, is extended to a class of dynamical
solutions supporting arbitrarily large, nondissipative traveling waves, using
techniques previously applied to global and local topological defects. These
solutions can then be used in conjunction with S-duality to obtain more general
solitonic solutions for various axidilaton-Maxwell theories. As an example, a
set of dynamical solutions is found for axion, dilaton, and Maxwell fields in
low energy heterotic string theory using the SL(2,R) invariance of the
equations of motion.

Targets consisting of 3,4He implanted into thin aluminum foils (approximately
100, 200 or 600 ug/cm^2) were prepared using intense (a few uA) helium beams at
low energy (approximately 20, 40 or 100 keV). Uniformity of the implantation
was achieved by a beam raster across a 12 mm diameter tantalum collimator at
the rates of 0.1 Hz in the vertical direction and 1 Hz in the horizontal
direction. Helium implantation into the very thin (approximately 80-100
ug/cm^2) aluminum foils failed to produce useful targets (with only
approximately 10% of the helium retained) due to an under estimation of the
range by the code SRIM. The range of low energy helium in aluminum predicted by
Northcliffe and Shilling and the NIST online tabulation are observed on the
other hand to over estimate the range of low energy helium ions in aluminum. An
attempt to increase the amount of helium by implanting a second deeper layer
was also carried out, but it did not significantly increase the helium content
beyond the blistering limit (approximately 6 x 10^17 helium/cm^2). The
implanted targets were bombarded with moderately intense 4He and 16O beams of
50-100 particle nA . Rutherford Back Scattering of 1.0 and 2.5 MeV proton beams
and recoil helium from 15.0 MeV oxygen beams were used to study the helium
content and profile before, during and after bombardments. We observed the
helium content and profile to be very stable even after a prolonged bombardment
(up to two days) with moderately intense beams of 16O or 4He. Helium implanted
into thin (aluminum) foils is a good choice for thin helium targets needed, for
example, for a measurement of the 3he(a,g)7Be reaction and the associated S34
astrophysical cross section factor (S-factor).
