Landau-Stark states — •Andrey R. Kolovsky — Kirensky Institute of Physics, 660036 Krasnoyarsk, Russia

The term "Landau-Stark states" refers to eigenstates of a charged particle in a 2D lattice in the presence of normal to the lattice plane magnetic and in-plane electric fields. I shall report the recent progress in understanding unusual properties of the Landau-Stark states [1,2] and discuss application of this newly developed theory to the Hall effect with cold atoms subjected to synthetic electric and magnetic fields [3].
