Stability of the Mott phase in excitonic double layers
K. Ziegler, R. Ya. Kezerashvili
We study the stability of excitonic Mott phases in the presence of a periodic potential and a non-local exciton-exciton interaction. The non-local interaction is treated in a mean-…

Edge modes in chiral electron double layers
Klaus Ziegler, Roman Ya. Kezerashvili
We study the quasiparticles in chiral double layers with electron pairing within the framework of the Bogoliubov de Gennes equation. In the presence of an edge it is demonstrated t…

Electron-hole superfluidity controlled by a periodic potential
O. L. Berman, R. Ya. Kezerashvili, Y. E. Lozovik +1
We propose to control of an electron-hole superfluid in semiconductor coupled quantum wells and double layers of two-dimensional (2D) material by an external periodic field. This c…
