Confinement and finite-range effects in a quasi-two-dimensional gas of fermionic dimers
Giovanni Midei, Jordi Boronat, Grigory E. Astrakharchik
We investigate the ground-state properties of ultracold two-component Fermi gases in the presence of a transverse harmonic potential, focusing on the strongly interacting regime in…
Realization of repulsive polarons in the strongly correlated regime
René Henke, Jesper Levinsen, Meera M. Parish +4
Mobile impurities interacting with a quantum medium form quasiparticles known as polarons, a central concept in many-body physics. While the quantum impurity problem has been exten…
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…
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…
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…
