Clustered Superfluids in the One Dimensional Bose-Hubbard model with extended correlated hopping
Julia Stasińska, Omjyoti Dutta, Luca Barbiero +2
Bosonic lattice systems with non-trivial interactions represent an intriguing platform to study exotic phases of matter. Here, we study the effects of extended correlated hopping p…
Effects of extended correlated hopping in a bose-bose mixture
Julia Stasińska, Ravindra W. Chhajlany, Omjyoti Dutta +1
We study the effects of assisted tunneling or correlated hopping between next nearest neighbours in a two species Bose-Hubbard system. The system is the bosonic analong of the ferm…
Ferroelectric nano-traps for polar molecules
Omjyoti Dutta, Geza Giedke
We propose and analyze an electrostatic-optical nano-scale trap for cold diatomic polar molecules. The main ingredient of our proposal is an square-array of ferroelectric nano-rods…
Synthetic Random Flux Model in a periodically-driven optical lattice
Jan Major, Marcin Płodzień, Omjyoti Dutta +1
We propose a realization of a synthetic Random Flux Model in a two-dimensional optical lattice. Starting from Bose-Hubbard Hamiltonian for two atom species we show how to use fast-…
At the limits of criticality-based quantum metrology: apparent super-Heisenberg scaling revisited
Marek M. Rams, Piotr Sierant, Omjyoti Dutta +2
We address the question whether the super-Heisenberg scaling for quantum estimation is realizable. We unify the results of two approaches. In the first one, the original system is…
Solitons in one-dimensional lattices with a flat band
D. Bercioux, O. Dutta, E. Rico
We investigate the spectral properties of a quasi-one-dimensional lattice in two possible dimerisation configurations. Both configurations are characterized by the same lattice top…
