Superfluidity of two- dimensional excitons in flat and harmonic traps

Yu. E. Lozovik, I. L. Kurbakov, M. Willander

Superfluid exciton density and superfluid transition (crossover) temperature are calculated for 2D excitons in large-size flat and harmonic traps. A generalized local density appro…

Effects of strong correlations for 2D Bose-Einstein condensed dipolar excitons

Yu. E. Lozovik, I. L. Kurbakov, G. E. Astrakharchik +2

By doing quantum Monte Carlo ab initio simulations we show that dipolar excitons, which are now under experimental study, actually are strongly correlated systems. Strong correlati…

Quantum Wire Hybridized with a Single-Level Impurity

Igor V. Lerner, Vladimir I. Yudson, Igor V. Yurkevich

We have studied low-temperature properties of interacting electrons in a one-dimensional quantum wire (Luttinger liquid) side-hybridized with a single-level impurity. The hybridiza…

Bose-Einstein condensation and Superfluidity of magnetoexcitons in Graphene

Oleg L. Berman, Yurii E. Lozovik, Godfrey Gumbs

We propose experiments to observe Bose-Einstein condensation (BEC) and superfluidity of quasi-two-dimensional (2D) spatially indirect magnetoexcitons in bilayer graphene. The magne…

Optical spectra, crystal-field parameters, and magnetic susceptibility of the new multiferroic NdFe3(BO3)4

M. N. Popova, E. P. Chukalina, T. N. Stanislavchuk +6

We report high-resolution optical absorption spectra for NdFe3(BO3)4 trigonal single crystal which is known to exhibit a giant magnetoelectric effect below the temperature of magne…
