Quantum gravity, torsion, parity violation, and all that

Exact dynamics of a reaction-diffusion model with spatially alternating rates
(American Physical Society, 2005-05)
We present the exact solution for the full dynamics of a nonequilibrium spin chain and its dual reaction-diffusion model, for arbitrary initial conditions. The spin chain is driven out of equilibrium by coupling alternating ...
Nature of the condensate in mass transport models
(American Physical Society, 2005-05-13)
We study the phenomenon of real space condensation in the steady state of a class of one-dimensional mass transport models. We derive the criterion for the occurrence of a condensation transition and analyze the precise ...
alpha-states in de Sitter space
(American Physical Society, 2005-02)
Field theory in de Sitter space admits a one-parameter family of vacua determined by a superselection parameter alpha. Of these vacua, the Euclidean vacuum uniquely extrapolates to the vacuum of flat Minkowski space. States ...
Scanning near-field optical microscopy utilizing silicon nitride probe photoluminescence
(AIP Publishing, 2005-11)
We describe a simple method for performing high-resolution scanning near-field optical microscopy (SNOM). A commercial Si3N4 tip is illuminated by an intense light source, which causes the tip to emit redshifted (inelastically ...
Steady states of a nonequilibrium lattice gas
(American Physical Society, 2005-09)
We present a Monte Carlo study of a lattice gas driven out of equilibrium by a local hopping bias. Sites can be empty or occupied by one of two types of particles, which are distinguished by their response to the hopping ...
Sampling-time effects for persistence and survival in step structural fluctuations
(American Physical Soc, 2005-02-01)
General rules for predicting phase transitions in perovskites due to octahedral tilting
(American Physical Society, 2005-07-08)
Recent experiments on several oxide perovskites reveal that they undergo tilt phase transitions to higher-symmetry phases on increasing pressure and that dT(c)/dP < 0, contrary to a general rule previously proposed for ...
The field theory approach to percolation processes
(Academic Press Inc Elsevier Science, 2005-01-01)
Synthesis kinetics of CdSe quantum dots in trioctylphosphine oxide and in stearic acid
(AIP Publishing, 2005-04-01)
A diffusion-barrier model described the early evolution of size-dependent photoluminescence emission from CdSe quantum dots formed by organometallic synthesis. Emission peak widths, emission redshift rates, and nanocrystal ...
