Bose-Einstein condensation and superfluidity of magnetobiexcitons in quantum wells' and graphene superlattices
Oleg L. Berman, Roman Ya. Kezerashvili, Yurii E. Lozovik
We propose the Bose-Einstein condensation (BEC) and superfluidity of quasi-two-dimensional (2D) spatially indirect magnetobiexcitons in a slab of superlattice with alternating elec…
Anomalous optical transmission through a vortex lattice in a film of type-II superconductor
Oleg L. Berman, Yurii E. Lozovik, Maria V. Bogdanova +1
We study the effect of anomalous optical transmission through an array of vortices in a type-II superconducting film subjected to a strong magnetic field. The mechanism responsible…
Phase transitions in a system of indirect magnetoexcitons in coupled quantum wells at high magnetic field: the role of disorder
Oleg L. Berman, Yurii E. Lozovik, David W. Snoke +1
Collective properties of a quasi-two-dimensional (2D) system of spatially indirect magnetoexcitons in coupled quantum wells (CQW) in high magnetic field were analyzed in the pr…
Generalized Coherent State Derivation of TDDFT Equations for Superconductors
Oleg Berman, Shaul Mukamel
Equations of motion are derived for the normal and the anomalous single-electron density matrices of a Fermi liquid using a time dependent finite temperature generalized coherent s…
