Coordinate space representation of a one-dimensional odd-parity pseudopotential
Marc Camus-Sais, Abel Rojo-Francàs, 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…

Bose-Einstein condensation in exotic lattice geometries
Kamil Dutkiewicz, Marcin Płodzień, Abel Rojo-Francàs +3
Modern quantum engineering techniques allow for synthesizing quantum systems in exotic lattice geometries, from self-similar fractal networks to negatively curved hyperbolic graphs…

Counterflow of lattice polarons in harmonically confined optical lattices
Felipe Isaule, Abel Rojo-Francàs, Luis Morales-Molina +1
We study a mobile impurity in a one-dimensional harmonically confined optical lattice interacting repulsively with a bosonic bath. The behavior of the impurity across baths with su…
