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…
Thermal behavior of Bose-Einstein condensates of polar molecules
Juan Sánchez-Baena, Gerard Pascual, Raúl Bombín +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…
Temperature-induced miscibility of impurities in trapped Bose gases
G. Pascual, T. Wasak, A. Negretti +2
We study the thermal properties of impurities embedded in a repulsive Bose gas under a harmonic trapping potential. In order to obtain exact structural properties in this inhomogen…
Thermal-induced Local Imbalance in Repulsive Binary Bose Mixtures
Gerard Pascual, Gabriele Spada, Sebastiano Pilati +2
We study repulsive two-component Bose mixtures with equal populations and confined in a finite-size box through path-integral Monte Carlo simulations. For different values of the $…
Phase separation in binary Bose mixtures at finite temperature
G. Spada, L. Parisi, G. Pascual +5
We investigate the magnetic behavior of finite-temperature repulsive two-component Bose mixtures by means of exact path-integral Monte-Carlo simulations. Novel algorithms are imple…
Quasiparticle nature of the Bose polaron at finite temperature
Gerard Pascual, Jordi Boronat
The Bose polaron has attracted theoretical and experimental interest because the mobile impurity is surrounded by a bath that undergoes a superfluid-to-normal phase transition. Alt…
