Directional superradiance in a driven ultracold atomic gas in free-space
Sanaa Agarwal, Edwin Chaparro, Diego Barberena +6
Ultra-cold atomic systems are among the most promising platforms that have the potential to shed light on the complex behavior of many-body quantum systems. One prominent example i…
Disentangling Pauli blocking of atomic decay from cooperative radiation and atomic motion in a 2D Fermi gas
Thomas Bilitewski, Asier Piñeiro Orioli, Christian Sanner +6
The observation of Pauli blocking of atomic spontaneous decay via direct measurements of the atomic population requires the use of long-lived atomic gases where quantum statistics,…
Non-equilibrium Quantum Spin Dynamics from 2PI Functional Integral Techniques in the Schwinger Boson Representation
A. Schuckert, A. Piñeiro Orioli, J. Berges
We present a non-equilibrium quantum field theory approach to the initial-state dynamics of spin models based on two-particle irreducible (2PI) functional integral techniques. It e…
Kinetic theory of non-thermal fixed points in a Bose gas
Isara Chantesana, Asier Piñeiro Orioli, Thomas Gasenzer
We outline a kinetic theory of non-thermal fixed points for the example of a dilute Bose gas, partially reviewing results obtained earlier, thereby extending, complementing, genera…
Universal scaling of unequal-time correlation functions in ultracold Bose gases far from equilibrium
A. Schachner, A. Piñeiro Orioli, J. Berges
We explore the far-from-equilibrium dynamics of Bose gases in a universal regime associated to nonthermal fixed points. While previous investigations concentrated on scaling functi…
