Equal-time approach to real-time dynamics of quantum fields
Robert Ott, Torsten V. Zache, Jürgen Berges
We employ the equal-time formulation of quantum field theory to derive effective kinetic theories, first for a weakly coupled non-relativistic Bose gas, and then for a strongly cor…
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 $…
Quantum thermalization of gauge theories: chaos, turbulence and universality
Niklas Mueller, Torsten V. Zache, Robert Ott
In this talk, we discuss real-time thermalization dynamics of Lattice Gauge Theory in 2+1 spacetime dimensions. While classical thermalization is commonly associated…
Thermalization dynamics of a gauge theory on a quantum simulator
Zhao-Yu Zhou, Guo-Xian Su, Jad C. Halimeh +7
Gauge theories form the foundation of modern physics, with applications ranging from elementary particle physics and early-universe cosmology to condensed matter systems. We perfor…
Thermalization of Gauge Theories from their Entanglement Spectrum
Niklas Mueller, Torsten V. Zache, Robert Ott
Using dual theories embedded into a larger unphysical Hilbert space along entanglement cuts, we study the Entanglement Structure of lattice gauge theory in s…
Scalable cold-atom quantum simulator for two-dimensional QED
Robert Ott, Torsten V. Zache, Fred Jendrzejewski +1
We propose a scalable analog quantum simulator for quantum electrodynamics (QED) in two spatial dimensions. The setup for the U(1) lattice gauge field theory employs inter-species…
