Physical Review A

Comment on “Phenomenological damping in optical response tensors”

G E Stedman, S. Naguleswaran, Davıd L. Andrews, Luciana C. Dávila Romero

Abstract

Damping factors arise from static as well as dynamic perturbations. These must appear with constant sign in the perturbation theory denominators for compatibility with quantum mechanics, conformity with time-reversal symmetry, and agreement with experiment.

A density matrix approach to problems in time-dependent perturbation theory

M Roberts, W. E. Hagston

It is demonstrated that the density matrix method may be applied to problems in time-dependent perturbation theory. The advantages of the method are that it is compact, systematic and the effects of radiation damping can be readily treated on a phenomenological basis.

Reflecting boundaries and massless factorized sattering in to dmensions

João Nuno Garcia Nobre Prata

This thesis is concerned with two-dimensional models that are integrable in the presence of a boundary and whose spectrum in the bulk is constituted of massless particles. Although there is already a vast literature on the subject (e.g. Kondo and Callan-Rubakov models), the common minimal denominator in all these situations is the fact that the bulk theory is conformal invariant and it is the boundary that is responsible for the broken scale invariance. Here, our purpose is to consider the alternative situation, where the boundary respects the conformal invariance of the theory and the renormalization group trajectory is controlled by a bulk perturbation. The model in question is the principal chiral model at level k = 1. We propose the set of permissible boundary conditions suggested by the symmetries of the problem and compute the corresponding minimal reflection matrices. For one of the boundary conditions we compute the boundary ground state energy and the boundary entropy using the technique of boundary thermodynamic Bethe ansatz. In the infrared limit our results are shown to be in complete agreement with the predictions of the boundary conformal field theory approach. Finally, we consider the classical supersymmetric Liouville theory on the half-line and compute the boundary conditions compatible with the superconformal invariance. We construct an infinite set of commuting integrals of motion using Lax-pair techniques and discuss some aspects of the quantum theory as well as its relation to the super Korteweg-de Vries equation.

Dynamical reduction theory of Einstein-Podolsky-Rosen correlations and a possible origin of CP violations

Daniel I. Fivel

We show that there is essentially only one way to construct a stochastic Schr\"odinger equation that gives a dynamical account of the transformation of entangled into factorized states and is consistent with both quantum mechanics and required symmetries. The noisy, nonlinear term is a unimodular scalar multiple of the time-reversal operator that must be present whenever a Hamiltonian term in the Schr\"odinger equation can distinguish the factorized constituents of an entangled state. The dynamical mechanism involved in the transformation of entangled into factorized states provides an explanation for the fact that Einstein-Podolsky-Rosen correlations appear in a time determined by the response of the measuring device and independent of the distance between the particles. The dependence on the response time of the measuring device may be testable through a delay in observing the collapse of mesoscopic ``Schr\"odinger cat'' states in ion traps. It is further shown that there are situations where a two-particle interaction can induce a nonlinear term by virtue of coupling to decay modes that distinguish factorized constituents of an entangled state. We show that this should happen in the neutral $K$-meson system where the entangled ${K}_{L}$ state is pushed slightly in the direction of a factorized constituent ${(K}_{0}$ or $\overline{{K}_{0}})$ as a consequence of the fact that these can be distinguished via the sign of the charged lepton in a semileptonic decay mode. The result is a $\mathrm{CP}$ violation that is within 20% of the experimental value.
