Tachyonic and parametric instabilities in an extended bosonic Josephson junction
Laura Batini, Sebastian Erne, Jörg Schmiedmayer +1
We study the dynamics and decay of quantum phase coherence for Bose-Einstein condensates in tunnel-coupled quantum wires. The two elongated Bose-Einstein condensates exhibit a wide…
Particle production and hadronization temperature in the massive Schwinger model
Laura Batini, Lara Kuhn, Jürgen Berges +1
We study the pair production, string breaking, and hadronization of a receding electron-positron pair using the bosonized version of the massive Schwinger model in quantum electrod…
Non-equilibrium dynamics of fluctuations in an ultra-cold atomic mixture
Apoorva Hegde, Robert Ott, Andy Xia +3
We investigate an ultra-cold mixture of Bose gases interacting via spin-changing collisions by studying the dynamics of spin fluctuations. The experimental implementation employs $…
Stability analysis of non-thermal fixed points in longitudinally expanding kinetic theory
Aleksandr N. Mikheev, Aleksas Mazeliauskas, Jürgen Berges
We use the Hamiltonian formulation of kinetic theory to perform a stability analysis of non-thermal fixed points in a non-Abelian plasma. We construct a perturbative expansion of t…
QCD thermalization: Ab initio approaches and interdisciplinary connections
Jürgen Berges, Michal P. Heller, Aleksas Mazeliauskas +1
Heavy-ion collisions at BNL's Relativistic Heavy Ion Collider and CERN's Large Hadron Collider provide strong evidence for the formation of a quark-gluon plasma, with temperatures…
Entanglement and thermalization
Jürgen Berges, Stefan Floerchinger, Raju Venugopalan
In a quantum field theory, apparent thermalization can be a consequence of entanglement as opposed to scatterings. We discuss here how this can help to explain open puzzles such as…
Thermal excitation spectrum from entanglement in an expanding quantum string
Jürgen Berges, Stefan Floerchinger, Raju Venugopalan
A surprising result in collisions is that the particle spectra from the string formed between the expanding quark-antiquark pair have thermal properties even though scatt…
How brightly does the Glasma shine? Photon production off-equilibrium
Jürgen Berges, Klaus Reygers, Naoto Tanji +1
We present a parametric estimate of photon production at early times in heavy-ion collisions based on a consistent weak coupling thermalization scenario. We quantify the contributi…
Inflationary preheating dynamics with ultracold atoms
Torsten V. Zache, Valentin Kasper, Jürgen Berges
We discuss the amplification of loop corrections in quantum many-body systems through dynamical instabilities. As an example, we investigate both analytically and numerically a two…
Turbulent thermalization process in high-energy heavy-ion collisions
Jürgen Berges, Björn Schenke, Sören Schlichting +1
We discuss the onset of the thermalization process in high-energy heavy-ion collisions from a weak coupling perspective, using classical-statistical real-time lattice simulations a…
