Diffusion in interacting two-dimensional systems under a uniform magnetic field
Łukasz Iwanek, Marcin Mierzejewski, Adam S. Sajna
The dynamics of interacting particles in orbital magnetic fields are notoriously difficult to study, as this physics is inherently connected to electronic correlations in two-dimen…
Semiclassical dynamics of a disordered two-dimensional Hubbard model with long-range interactions
Adam S. Sajna, Anatoli Polkovnikov
Quench dynamics in a two-dimensional system of interacting fermions is analyzed within the semiclassical truncated Wigner approximation (TWA). The models with short-range and long-…
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…
Conductivity of strongly correlated bosons in optical lattices in an Abelian synthetic magnetic field
A. S. Sajna, T. P. Polak, R. Micnas
Topological phase engineering of neutral bosons loaded in an optical lattice opens a new window for manipulating of transport phenomena in such systems. Exploiting the Bose Hubbard…
