Enhanced strong interaction effect in synthetic spin-orbit coupling with mixed spin symmetry
Ayaka Usui, Abel Rojo-Francà s, 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.…
Stable collective charging of ultracold atoms quantum batteries
Abel Rojo-Francà s, 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…
Ultracold dipolar bosons trapped in atomtronic circuits
Marc Rovirola, Héctor Briongos-Merino, Bruno Juliá-DÃaz +1
We consider a ring-shaped triple-well potential with few polar bosons with in-plane dipole orientation. By diagonalizing the extended Bose-Hubbard Hamiltonian, we investigate the g…
Bound impurities in a one-dimensional Bose lattice gas: low-energy properties and quench-induced dynamics
Felipe Isaule, Abel Rojo-Francà s, Bruno Juliá-DÃaz
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…
