Vortices in dipolar condensates of interlayer excitons
Sara Conti, Andrey Chaves, Luis A. Pena Ardila +2
Recently observed signatures of Bose-Einstein condensation and superfluidity of dipolar excitons have drawn enormous attention to excitonic semiconductor bilayers. In superfluids,…
Modified mean field ansatz for charged polarons in a Bose-Einstein condensate
Ubaldo Cavazos Olivas, Luis A. Peña Ardila, Krzysztof Jachymski
Ionic Bose polarons are quantum entities emerging from the interaction between an ion and a Bose-Einstein condensate (BEC), featuring long-ranged interactions that can compete with…
Fermi polaron in atom-ion hybrid systems
Renato Pessoa, S. A Vitiello, L. A Peña Ardila
Atom-ion hybrid systems are promising platforms for the quantum simulation of polaron physics in certain quantum materials. Here, we investigate the ionic Fermi polaron, a charged…
Universal properties of dipolar Bose polarons in two dimensions
Juan Sánchez-Baena, Luis A. Peña Ardila, Grigory Astrakharchik +1
We study the quasiparticle properties of a dipolar impurity immersed in a two-dimensional dipolar bath. We use the ab-initio Diffusion Monte Carlo technique to determine the polaro…
Non-equilibrium dynamics of dipolar polarons
Artem G. Volosniev, Giacomo Bighin, Luis Santos +1
We study the out-of-equilibrium quantum dynamics of dipolar polarons, i.e., impurities immersed in a dipolar Bose-Einstein condensate, after a quench of the impurity-boson interact…
Many-body bound states and induced interactions of charged impurities in a bosonic bath
G. E. Astrakharchik, L. A. Peña Ardila, K. Jachymski +1
Induced interactions and bound states of charge carriers immersed in a quantum medium are crucial for the investigation of quantum transport. Ultracold atom-ion systems can provide…
Anomalous buoyancy of quantum bubbles in immiscible Bose mixtures
Daniel Edler, L. A. Peña Ardila, Cesar R. Cabrera +1
Buoyancy is a well-known effect in immiscible binary Bose-Einstein condensates. Depending on the differential confinement experienced by the two components, a bubble of one compone…
The Bose polaron problem: effect of mass imbalance on binding energy
L. A. Peña Ardila, S. Giorgini
By means of Quantum Monte Carlo methods we calculate the binding energy of an impurity immersed in a Bose-Einstein condensate at T = 0. The focus is on the attractive branch of the…
Impurity in a Bose-Einstein condensate: study of the attractive and repulsive branch using quantum Monte-Carlo methods
L. A. Peña Ardila, S. Giorgini
We investigate the properties of an impurity immersed in a dilute Bose gas at zero temperature using quantum Monte-Carlo methods. The interactions between bosons are modeled by a h…
