Two band model for coherent excitonic condensates
V. Apinyan, T. K. Kopeć
We consider the excitonic correlations in the two band solid state system composed of the valence band and conduction band electrons. We treat the phase coherence mechanism in the…
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…
Phase coherence and spectral functions in the two-dimensional excitonic systems
V. Apinyan, T. K. Kopeć
The nonlocal correlation mechanism between excitonic pairs is considered for a two dimensional exciton system. On the base of the unitary decomposition of the usual electron operat…
