Bardeen-Cooper-Schrieffer State Representation and Pairing in the Fermionic Tonks-Girardeau Gas
Francesc Sabater, Abel Rojo-Francàs, Grigori E. Astrakharchik +1
We introduce an alternative expression for the ground state wave function of the fermionic Tonks-Girardeau gas. Our wave function is constructed based on the occupation numbers and…
Stable collective charging of ultracold atoms quantum batteries
Abel Rojo-Francàs, Felipe Isaule, Alan C. Santos +2
We propose a novel quantum battery realized with a few interacting particles in a three-well system with different on-site energies, which could be realized with ultracold atom pla…
Enhanced strong interaction effect in synthetic spin-orbit coupling with mixed spin symmetry
Ayaka Usui, Abel Rojo-Francàs, James Schloss +1
Synthetic spin-orbit coupling in cold atoms couples the pseudo-spin and spatial degrees of freedom, and therefore the inherent spin symmetry of the system plays an important role.…
Bound impurities in a one-dimensional Bose lattice gas: low-energy properties and quench-induced dynamics
Felipe Isaule, Abel Rojo-Francàs, Bruno Juliá-Díaz
We study two mobile bosonic impurities immersed in a one-dimensional optical lattice and interacting with a bosonic bath. We employ the exact diagonalization method for small perio…
Anomalous quantum transport in fractal lattices
Abel Rojo-Francàs, Priyanshu Pansari, Utso Bhattacharya +2
Fractal lattices are self-similar structures with repeated patterns on different scales. As in other aperiodic lattices, the absence of translational symmetry can give rise to quan…
