Equal-spin and opposite-spin density-density correlations in the BCS-BEC crossover: Gauge Symmetry, Pauli Exclusion Principle, Wick's Theorem and Experiments
Nikolai Kaschewski, Axel Pelster, Carlos A. R. Sá de Melo
We develop a general theory of spin-dependent density-density correlations, that is valid for any temperature, interactions, dimensions and mass or population status of Fermi gases…
From Lasers to Photon Bose--Einstein Condensates: A Unified Description via an Open-Dissipative Bose--Einstein Distribution
Joshua Krauß, Enrico Stein, Axel Pelster
Photon condensation was first experimentally realized in 2010 within a dye-filled microcavity at room temperature. Since then, interest in the field has increased significantly, as…
Weighted Hartree-Fock-Bogoliubov method for interacting fermions: An application to ultracold Fermi superfluids
Nikolai Kaschewski, Axel Pelster, Carlos A. R. Sá de Melo
For several decades it has been known that divergences arise in the ground-state energy and chemical potential of unitary superfluids, where the scattering length diverges, due to…
Understanding Floquet Resonances in Ultracold Gas Scattering
Christoph Dauer, Axel Pelster, Sebastian Eggert
Scattering by a short-range potential with time-periodic interaction strength is investigated with a Floquet-scattering theory. Sharp resonances occur, at which the s-wave scatteri…
Dimensional Crossover in a Quantum Gas of Light
Kirankumar Karkihalli Umesh, Julian Schulz, Julian Schmitt +3
The dimensionality of a system profoundly influences its physical behaviour, leading to the emergence of different states of matter in many-body quantum systems. In lower dimension…
Indication of critical scaling in time during the relaxation of an open quantum system
Ling-Na Wu, Jens Nettersheim, Julian Feß +6
Phase transitions correspond to the singular behavior of physical systems in response to continuous control parameters like temperature or external fields. Near continuous phase tr…
