Relative entropic uncertainty relation
Stefan Floerchinger, Tobias Haas, Ben Hoeber
Quantum uncertainty relations are formulated in terms of relative entropy between distributions of measurement outcomes and suitable reference distributions with maximum entropy. T…
Spatial entanglement in interacting Bose-Einstein condensates
N. Sánchez-Kuntz, S. Floerchinger
The entanglement between spatial regions in an interacting Bose-Einstein condensate is investigated using a quantum field theoretic formalism. Regions that are small compared to th…
Second law of thermodynamics for relativistic fluids formulated with relative entropy
Neil Dowling, Stefan Floerchinger, Tobias Haas
The second law of thermodynamics is discussed and reformulated from a quantum information theoretic perspective for open quantum systems using relative entropy. Specifically, the r…
General relativistic non-ideal fluid equations for dark matter from a truncated cumulant expansion
Alaric Erschfeld, Stefan Floerchinger, Maximilian Rupprecht
A new truncation scheme based on the cumulant expansion of the one-particle phase-space distribution function for dark matter particles is developed. Extending the method of moment…
Real scalar field, non-relativistic limit, and cosmological expansion
Lars Helge Heyen, Stefan Floerchinger
The existing transformation from a relativistic real scalar field to a complex non-relativistic scalar field by Namjoo, Guth, and Kaiser is generalized from Minkowski space to a mo…
Model comparison for initial density fluctuations in high energy heavy ion collisions
Stefan Floerchinger, Eduardo Grossi, Kianusch Vahid Yousefnia
Four models for the initial conditions of a fluid dynamic description of high energy heavy ion collisions are analysed and compared. We study expectation values and event-by-event…
