Bound-state formation and thermalization within the Lindblad approach

Jan Rais, Hendrik van Hees, Carsten Greiner

The Lindblad equation, as one approach to open quantum systems, describes the density matrix of a particle or a chain of interacting particles, which are in contact with a thermal…

Bound state formation within the Lindblad approach

Jan Rais, Hendrik van Hees, Carsten Greiner

The Lindblad master equation is a frequently used Markovian approach to describe open quantum systems in terms of the temporal evolution of a reduced density matrix. Here, the ther…

Solving the Lindblad equation with methods from computational fluid dynamics

Jan Rais, Adrian Koenigstein, Niklas Zorbach +1

Liouvillian dynamics describes the evolution of a density operator in closed quantum systems. One extension towards open quantum systems is provided by the Lindblad equation. It is…

Open Quantum Systems with Kadanoff-Baym Equations

Tim Neidig, Jan Rais, Marcus Bleicher +2

We study the temporal evolution of quantum mechanical fermionic particles exhibiting one bound state within a one-dimensional attractive square-well potential in a heat bath of bos…

Bound State Formation in Time Dependent Potentials

Jan Rais, Hendrik van Hees, Carsten Greiner

We study the temporal formation of quantum mechanical bound states within a one-dimensional attractive square-well potential, by first solving the time-independent Schroedinger equ…

The Shear Viscosity to Entropy Density Ratio of Hagedorn States

Jan Rais, Kai Gallmeister, Carsten Greiner

The fireball concept of Rolf Hagedorn, developed in the 1960's, is an alternative description of hadronic matter. Using a recently derived mass spectrum, we use the transport model…
