Persistence of Quantum Information
Michael Schulz, Steffen Trimper
There is an increasing interest in the role of macroscopic environments to our understanding of the basics of quantum theory. The knowledge of the implications of the quantum theor…
Spatiotemporal Memory in a Diffusion-Reaction System
Michael Schulz, Steffen Trimper, Knud Zabrocki
We consider a reaction-diffusion process with retardation. The particles, immersed in traps initially, remain inactive until another particle is annihilated spontaneously with a ra…
Size and doping effects on the coercive field of ferroelectric nanoparticles
Th. Michael, S. Trimper, J. M. Wesselinowa
A microscopic model for describing ferroelectric nanoparticles is proposed which allows us to calculate the polarization as a function of an external electric field, the temperatur…
Master Equation and Two Heat Reservoirs
Steffen Trimper
We analyze a simple spin-flip process under the presence of two heat reservoirs. While one flip process is triggered by a bath at temperature , the inverse process is activated…
Relationship between a Non-Markovian Process and Fokker-Planck Equation
Knud Zabrocki, Steffen Trimper, Svetlana Tatur +1
We demonstrate the equivalence of a Non--Markovian evolution equation with a linear memory--coupling and a Fokker--Planck equation (FPE). In case the feedback term offers a direct…
On the Glauber model in a quantum representation
Thomas Michael, Steffen Trimper, Michael Schulz
The Glauber model is reconsidered based on a quantum formulation of the Master equation. Unlike the conventional approach the temperature and the Ising energy are included from the…
