Quantum simulation of relativistic fields interacting with artificial gravity in 2D bichromatic optical lattices — •Nikodem Szpak — Fakultät für Physik, Universität Duisburg-Essen

We present our latest results on the possibilities of quantum simulation of relativistic fields in 2-dimensional bichromatic optical lattices. Geometry and relative strength of the laser beams define the properties of the effective quantum field and set the mass-gap of its ground-state excitations (particles and antiparticles). Local static or time-dependent amplitude and/or phase modulations can then introduce effective curved geometry and gravitational potential. The last can be used for simulation of gravitational lensing or interaction with strong gravitational waves -- beyond the range of any direct experiments.
