Mobile impurity interacting with a Hubbard chain and the role of Friedel oscillations
Felipe Isaule, Abel Rojo-Francà s, Duc Tuan Hoang +3
This work examines a mobile impurity interacting with a bath of a few spin- and spin- fermions in a small one-dimensional open lattice system. We study ground…

Coordinate space representation of a one-dimensional odd-parity pseudopotential
Marc Camus-Sais, Abel Rojo-Francà s, Grigori E. Astrakharchik +1
We propose a discrete-space representation of a one-dimensional zero-range odd-parity pseudopotential. The proposed representation is validated by applying it to the analytically s…

Quantum Monte Carlo study of systems interacting via long-range interactions mediated by a cavity
Marta DomÃnguez-Navarro, Abel Rojo-Francà s, Bruno Juliá-DÃaz +1
We study one-dimensional quantum gases in continuous space with cavity-mediated infinite-range interactions using variational and diffusion Monte Carlo methods. Starting from the e…
