Accessing finite momentum excitations of the one-dimensional Bose-Hubbard model using superlattice modulation spectroscopy
Karla Loida, Jean-Sebastien Bernier, Roberta Citro +2
We investigate the response to superlattice modulation of a bosonic quantum gas confined to arrays of tubes emulating the one-dimensional Bose-Hubbard model. We demonstrate, using…
Probing the bond order wave phase transitions of the ionic Hubbard model by superlattice modulation spectroscopy
Karla Loida, Jean-Sebastien Bernier, Roberta Citro +2
An exotic phase, the bond order wave, characterized by the spontaneous dimerization of the hopping, has been predicted to exist sandwiched between the band and Mott insulators in s…
Thermometry of ultracold fermions by (super)lattice modulation spectroscopy
Karla Loida, Ameneh Sheikhan, Corinna Kollath
We theoretically consider non-interacting fermions confined to optical lattices and apply a lattice amplitude modulation that we choose to be either homogeneous or of superlattice…
