Curved and expanding spacetime geometries in Bose-Einstein condensates
Mireia Tolosa-Simeón, Álvaro Parra-López, Natalia Sánchez-Kuntz +9
Phonons have the characteristic linear dispersion relation of massless relativistic particles. They arise as low energy excitations of Bose-Einstein condensates and, in nonhomogene…
Quantum field simulator for dynamics in curved spacetime
Celia Viermann, Marius Sparn, Nikolas Liebster +9
The observed large-scale structure in our Universe is seen as a result of quantum fluctuations amplified by spacetime evolution. This, and related problems in cosmology, asks for a…
High signal to noise absorption imaging of alkali atoms at moderate magnetic fields
Maurus Hans, Finn Schmutte, Celia Viermann +4
We present an improved scheme for absorption imaging of alkali atoms at moderate magnetic fields, where the excited state is well in the Paschen-Back regime but the ground state hy…
Cosmic Structure Formation with Kinetic Field Theory
Matthias Bartelmann, Elena Kozlikin, Robert Lilow +7
Kinetic Field Theory (KFT) is a statistical field theory for an ensemble of point-like classical particles in or out of equilibrium. We review its application to cosmological struc…
A Model for Hydrodynamics in Kinetic Field Theory
C. Viermann, J. T. Schneider, R. Lilow +4
In this work, we introduce an effective model for both ideal and viscous fluid dynamics within the framework of kinetic field theory (KFT). The main application we have in mind is…
Resummed Kinetic Field Theory: general formalism and linear structure growth from Newtonian particle dynamics
Robert Lilow, Felix Fabis, Elena Kozlikin +2
In earlier work, we have developed a nonequilibrium statistical field theory description of cosmic structure formation, dubbed Kinetic Field Theory (KFT), which is based on the Ham…
Non-equilibrium statistical field theory for classical particles: Impact of correlated initial conditions on non-ideal gases
Elena Kozlikin, Felix Fabis, Robert Lilow +2
We use the non-equilibrium statistical field theory for classical particles recently developed by Mazenko and Das and Mazenko, together with the free generating functional for part…
Non-equilibrium statistical field theory for classical particles: Non-linear structure evolution with first-order interaction
Matthias Bartelmann, Felix Fabis, Daniel Berg +3
We calculate the power spectrum of density fluctuations in the statistical non-equilibrium field theory for classical, microscopic degrees of freedom to first order in the interact…
Non-equilibrium statistical field theory for classical particles: Linear and mildly non-linear evolution of cosmological density power spectra
Matthias Bartelmann, Felix Fabis, Daniel Berg +3
We use the non-equlibrium statistical field theory for classical particles, recently developed by Mazenko and Das and Mazenko, together with the free generating functional we have…
Non-equilibrium statistical field theory for classical particles: Basic kinetic theory
Celia Viermann, Felix Fabis, Elena Kozlikin +2
Recently Mazenko and Das and Mazenko introduced a non-equilibrium field theoretical approach to describe the statistical properties of a classical particle ensemble starting from t…
A microscopic, non-equilibrium, statistical field theory for cosmic structure formation
Matthias Bartelmann, Felix Fabis, Daniel Berg +3
Building upon the recent pioneering work by Mazenko and by Das and Mazenko, we develop a microscopic, non-equilibrium, statistical field theory for initially correlated canonical e…
