Realizing a scalable building block of a U(1) gauge theory with cold atomic mixtures
Alexander Mil, Torsten V. Zache, Apoorva Hegde +6
In the fundamental laws of physics, gauge fields mediate the interaction between charged particles. An example is quantum electrodynamics -- the theory of electrons interacting wit…
Experimental extraction of the quantum effective action for a non-equilibrium many-body system
Maximilian Prüfer, Torsten V. Zache, Philipp Kunkel +5
Far-from-equilibrium situations are ubiquitous in nature. They are responsible for a wealth of phenomena, which are not simple extensions of near-equilibrium properties, ranging fr…
Extracting the field theory description of a quantum many-body system from experimental data
Torsten V. Zache, Thomas Schweigler, Sebastian Erne +2
Quantum field theory is a powerful tool to describe the relevant physics governing complex quantum many-body systems. Here we develop a general pathway to extract the irreducible b…
Non-cancellation of the parity anomaly in the strong-field regime of QED
Robert Ott, Torsten V. Zache, Niklas Mueller +1
Quantum fluctuations lead to an anomalous violation of parity symmetry in quantum electrodynamics for an even number of spatial dimensions. While the leading parity-odd electric cu…
