Tuning linear response dynamics near the Dirac points in the bosonic Mott insulator
A. S. Sajna
Optical lattice systems offer the possibility of creating and tuning Dirac points which are present in the tight-binding lattice dispersions. For example, such a behavior can be ac…

Effect of boson on-site repulsion on the superfluidity in the boson-fermion-Hubbard model
A. S. Sajna, R. Micnas
We analyze the finite-temperature phase diagram of the boson-fermion-Hubbard model with Feshbach converting interaction, using the coherent-state path-integral method. We show that…

Finite size effects and Hofstadter butterfly in a bosonic Mott insulator with relativistic dispersion background
A. S. Sajna, T. P. Polak
Gauge potentials with different configurations have been recently realized in the optical lattice experiments. It is remarkable that one of the simplest gauge can generate particle…
