Pairs, trimers and BCS-BEC crossover near a flat band: the sawtooth lattice
Giuliano Orso, Manpreet Singh
We investigate pairing and superconductivity in the attractive Fermi Hubbard model on the one-dimensional sawtooth lattice, which exhibits a flat band by fine-tuning the hopping ra…
Itinerant ferromagnetism in the repulsive Hubbard chain with anisotropic odd-wave attraction
Manpreet Singh, Sebastiano Pilati, Giuliano Orso
The ground-state properties of the Hubbard chain with on-site repulsion and anisotropic nearest-neighbor attraction are investigated by means of density matrix renormalization grou…
Mott insulator phases of non-locally coupled bosons in bilayer optical superlattices
Sayan Lahiri, Suman Mondal, Manpreet Singh +1
We investigate the ground state properties of a non-locally coupled bosonic system in a bilayer optical superlattice by considering bosons in one layer to be of softcore in nature…
Enhanced visibility of the Fulde-Ferrell-Larkin-Ovchinnikov state in one dimensional Bose-Fermi mixtures near the immiscibility point
Manpreet Singh, Giuliano Orso
Based on the matrix product states method, we investigate numerically the ground state properties of one-dimensional mixtures of repulsive bosons and spin-imbalanced attractive fer…
Two-leg ladder Bose Hubbard models with staggered fluxes
Rashi Sachdeva, Friederike Metz, Manpreet Singh +2
We investigate the ground state properties of ultracold atoms trapped in a two-leg ladder potential in the presence of an artificial magnetic field in a staggered configuration. We…
Anomalous pairing of bosons: Effect of multi body interactions in optical lattice
Manpreet Singh, Sebastian Greschner, Tapan Mishra
An interesting first order type phase transition between Mott lobes has been reported in Phys. Rev. Lett. 109, 135302 (2012) for a two-dimensional Bose-Hubbard model in the presenc…
