Quantum Nonequilibrium Steady States Induced by Repeated Interactions
(American Physical Society, 2009-05-22)
We study the steady state of a finite XX chain coupled at its boundaries to quantum reservoirs made of free spins that interact one after the other with the chain. The two-point correlations are calculated exactly, and it ...
Anomalous nucleation far from equilibrium
(American Physical Society, 2005-03-25)
We present precision Monte Carlo data and analytic arguments for an asymmetric exclusion process, involving two species of particles driven in opposite directions on a 2xL lattice. To resolve a stark discrepancy between ...
Physics Performance of a Low-Luminosity Low Energy Neutrino Factory
(American Physical Society, 2013-08-08)
We investigate the minimal performance, in terms of beam luminosity and detector size, of a neutrino factory to achieve a competitive physics reach for the determination of the mass hierarchy and the discovery of leptonic ...
Solving pure Yang-Mills theory in 2+1 dimensions
(American Physical Society, 2006-06-09)
We analytically compute the spectrum of the spin zero glueballs in the planar limit of pure Yang-Mills theory in 2+1 dimensions. The new ingredient is provided by our computation of a new nontrivial form of the ground state ...
Entrainment and Unit Velocity: Surprises in an Accelerated Exclusion Process
(American Physical Society, 2012-09-27)
We introduce a class of distance-dependent interactions in an accelerated exclusion process inspired by the observation of transcribing RNA polymerase speeding up when "pushed" by a trailing one. On a ring, the accelerated ...
Gauge Fields, Membranes, and Subdeterminant Vector Models
(American Physical Society, 2010-06-01)
We present a class of classically marginal N-vector models in d = 4 and d = 3 whose scalar potentials can be written as subdeterminants of symmetric matrices. The d = 3 case can be thought of as a generalization of the ...
Determination of antineutrino spectra from nuclear reactors
(American Physical Society, 2011-08-29)
In this paper we study the effect of well-known higher-order corrections to the allowed beta-decay spectrum on the determination of antineutrino spectra resulting from the decays of fission fragments. In particular, we try ...
Precision measurement of the neutron beta-decay asymmetry
(American Physical Society, 2013-03-25)
A new measurement of the neutron beta-decay asymmetry A(0) has been carried out by the UCNA Collaboration using polarized ultracold neutrons (UCNs) from the solid deuterium UCN source at the Los Alamos Neutron Science ...
Constraints on two-Higgs-doublet models at large tan beta from W and Z decays
(American Physical Soc, 2000-09-01)
Relaxation and glassy dynamics in disordered type-II superconductors
(American Physical Society, 2011-11-18)
We study the nonequilibrium relaxation kinetics of interacting magnetic flux lines in disordered type II superconductors at low temperatures and low magnetic fields by means of a three-dimensional elastic-line model and ...
