Finite-range effects in the unitary Fermi polaron
Renato Pessoa, S. A. Vitiello, L. A. Peña Ardila
Quantum Monte Carlo techniques are employed to study the properties of polarons in an ultracold Fermi gas, at and in the unitary regime using both a zero-range model and a…
Quantum behavior of a heavy impurity strongly coupled to a Bose gas
Jesper Levinsen, Luis A. Peña Ardila, Shuhei M. Yoshida +1
We investigate the problem of an infinitely heavy impurity interacting with a dilute Bose gas at zero temperature. When the impurity-boson interactions are short ranged, we show th…
Dynamical formation of polarons in a Bose-Einstein condensate: A variational approach
L. A. Peña Ardila
We investigate the non-equilibrium dynamics of an impurity coupled to a Bose-Einstein condensate, systematically compared with recent experimental results [M. G. Skou et al., Nat.…
Quantum droplets of dipolar mixtures
R. N. Bisset, L. A. Peña Ardila, L. Santos
Recently achieved two-component dipolar Bose-Einstein condensates open exciting possibilities for the study of mixtures of ultra-dilute quantum liquids. While non-dipolar self-boun…
Strong coupling Bose polarons in a two-dimensional gas
L. A. Peña Ardila, G. E. Astrakharchik, S. Giorgini
We study the properties of Bose polarons in two dimensions using quantum Monte Carlo techniques. Results for the binding energy, the effective mass, and the quasiparticle residue a…
Analyzing a Bose polaron across resonant interactions
L. A. Peña Ardila, N. B. Jörgensen, T. Pohl +3
Recently, two independent experiments reported the observation of long-lived polarons in a Bose-Einstein condensate, providing an excellent setting to study the generic scenario of…
