Universality of the negativity in the Lipkin-Meshkov-Glick model
H. Wichterich, J. Vidal, S. Bose
The entanglement between noncomplementary blocks of a many-body system, where a part of the system forms an ignored environment, is a largely untouched problem without analytic res…
Density dynamics from current auto-correlations at finite time- and length-scales
Robin Steinigeweg, Hannu Wichterich, Jochen Gemmer
We consider the increase of the spatial variance of some inhomogeneous, non-equilibrium density (particles, energy, etc.) in a periodic quantum system of condensed matter-type. Thi…
Heat Transport in Quantum Spin Chains: Stochastic Baths vs Quantum Trajectories
Carlos Mejia-Monasterio, Hannu Wichterich
We discuss the problem of heat conduction in quantum spin chain models. To investigate this problem it is necessary to consider the finite open system connected to heat baths. We d…
