Thermal behavior of Bose-Einstein condensates of polar molecules
Juan Sánchez-Baena, Gerard Pascual, Raúl BombÃn +2
We use the finite-temperature extended Gross-Pitaevskii equation (TeGPE) to study a condensate of dipolar NaCs molecules under the conditions of the very recent, breakthrough exper…

On polarons and dimerons in the two-dimensional attractive Hubbard model
Gerard Pascual, Jordi Boronat, Kris Van Houcke
A two-dimensional spin-up ideal Fermi gas interacting attractively with a spin-down impurity in the continuum undergoes, at zero temperature, a first-order phase transition from a…

The Bose polaron as thermometer of a trapped Bose gas: a quantum Monte Carlo study
Tomasz Wasak, Gerard Pascual, Gregory E. Astrakharchik +2
Quantum impurities interacting with quantum environments offer unique insights into many-body systems. Here, we explore the thermometric potential of a neutral impurity immersed in…
