Quantum Statistical Thermal Engine at the BCS-BEC crossover
Santiago Henríquez Lira, Felipe Isaule, Martín HvE Groves +3
We propose a quantum heat engine based on a two-component Fermi gas with s-wave contact interaction, operating across the BCS-BEC crossover. The work is extracted from the statisti…

S. Carmona-López, A. Matos-Abiague, F. Isaule +1
We theoretically investigate supercurrents of ultracold atoms in angularly ac-shaken ring lattices subjected to external rotation. Our results demonstrate how these supercurrents c…
