On A Local Carnot Engine
Steffen Trimper, Simone Artz
Starting from a master equation in a quantum Hamilton form we study analytically a nonequilibrium system which is coupled locally to two heat bathes at different temperatures. Base…
Competing Glauber and Kawasaki Dynamics
S. Artz, S. Trimper
Using a quantum formulation of the master equation we study a kinetic Ising model with competing stochastic processes: the Glauber dynamics with probability and the Kawasaki dy…
Diffusion with restrictions
S. Artz, M. Schulz, S. Trimper
A non--linear diffusion equation is derived by taking into account hopping rates depending on the occupation of next neighbouring sites. There appears additonal repulsive and attra…
Analytical Bethe Ansatz for quantum-algebra-invariant open spin chains
Simone Artz, Luca Mezincescu, Rafael I. Nepomechie
We determine the eigenvalues of the transfer matrices for integrable open quantum spin chains which are associated with the affine Lie algebras $A^{(2)}_{2n-1}, B^{(1)}_n, C^{(1)}_…
Spectrum of transfer matrix for -invariant open spin chain
Simone Artz, Luca Mezincescu, Rafael I. Nepomechie
We propose an expression for the eigenvalues of the transfer matrix for the -invariant open quantum spin chain associated with the fundamental representation of $A^{(2)}_…
