Bound states of the Duffin-Kemmer-Petiau equation with a mixed minimal-nonminimal vector cusp potential
Bound states the Duffin-Kemmer-Petiau equation
2010/12/23
The problem of spin-0 and spin-1 bosons subject to a general mixing of minimal and nonminimal vector cusp potentials is explored in a unified way in the context of the Duffin-Kemmer-Petiau theory. Eff...
Fusion of line operators in conformal sigma-models on supergroups, and the Hirota equation
line operators conformal sigma-models supergroups
2010/12/23
We study line operators in the two-dimensional sigma-model on PSl(n|n) using the current-current OPEs. We regularize and renormalize these line operators, and compute their fusion up to second order ...
Integrability of two-component nonautonomous nonlinear Schrödinger equation
two-component nonautonomous nonlinear Schrö dinger equation
2010/11/16
We investigate the integrability of generalized nonautonomous nonlinear Schr\"odinger (NLS) equations governing the dynamics of the single- and double-component Bose-Einstein condensates (BECs). The ...
Entropy Production in Nonequilibrium Systems Described by a Fokker-Planck Equation
Entropy production Irreversible systems Fokker-Planck equation
2010/10/13
We study the entropy production in nonequilibrium systems described by a Fokker-Planck equation. We have devised an expression for the entropy flux in the stationary state. We have found that the entr...
