Nano-Scale `Dark State' Optical Potentials for Cold Atoms
M. Łącki, M. Baranov, H. Pichler +1
We discuss generation of subwavelength optical barriers on the scale of tens of nanometers, as conservative optical potentials for cold atoms. These arise from non-adiabatic correc…
Dynamics of heat and mass transport in a quantum insulator
Mateusz Łącki, Dominique Delande, Jakub Zakrzewski
The real time evolution of two pieces of quantum insulators, initially at different temperatures, is studied when they are glued together. Specifically, each subsystem is taken as…
Bose-Hubbard model with random impurities: Multiband and nonlinear hopping effects
Julia Stasińska, Mateusz Łącki, Omjyoti Dutta +2
We investigate the phase diagrams of theoretical models describing bosonic atoms in a lattice in the presence of randomly localized impurities. By including multiband and nonlinear…
Disordered spinor Bose-Hubbard model
Mateusz Lacki, Simone Paganelli, Veronica Ahufinger +2
We study the zero temperature phase diagram of the disordered spin-1 Bose-Hubbard model in a 2-dimensional square lattice. To this aim, we use a mean field Gutzwiller ansatz and a…
