Topological phase transitions in tilted optical lattices

Dear Colleagues,

We are glad to invite you to the next CPQM Seminar on Topological phase transitions in tilted optical lattices to be given by Prof. Andrey Kolovsky

When: February 7, 16:00

Where: MR-351 TPOC4  (Red building)

 

SEMINAR ABSTRACT

By definition, Wannier-Stark states are eigenstates of a quantum particle in a tilted (biased) lattice. These states are well understood in one dimension but their extension into two dimensions continues to surprise researches. In the talk I briefly review main properties of Wannier-Stark states of a quantum particle in two-dimensional lattices and then highlight recent results for some particular lattices, where Wannier-Stark states possess interesting topological properties.
