Density of states and excitonic condensation in the double layer correlated systems
V. Apinyan, T. K. Kopeć
We consider the single-particle density of states (DOS) in the strongly correlated double layer (DL) system, without applied external fields. We demonstrate an unusual collapse eff…

Excitonic gap formation in neutral bilayer structures
V. Apinyan, T. K. Kopeć
We consider the pairing between conduction band electrons, and the valence band holes in the neutral bilayer-type structures. By employing the bilayer Hubbard model, we show the po…

The superfluid phase transition in two-dimensional excitonic systems
V. Apinyan, T. K. Kopeć
We study the superfluid phase transition in the two-dimensional (2D) excitonic system. Employing the extended Falicov-Kimball model (EFKM) and considering the local quantum correla…
