Abstract: We investigate the Dirac Kepler/Coulomb (KC) problem in 2+1 -dimensions where the charged particle (an electron) is simultaneously affected by a position-dependent effective mass term. In polar coordinates, we examine two instances: (i) the quantum… read more here.

Abstract: In recent years, photonics has proven itself as an excellent platform for emulation of relativistic phenomena. Here, we show an example of relativistic-like trapping in photonic system that realizes Dirac-like dispersion with spatially inhomogeneous mass… read more here.

DOI: 10.3390/nano12091437
Abstract: We predict Bose-Einstein condensation and superfluidity of dipolar excitons, formed by electron-hole pairs in spatially separated gapped hexagonal α−T3 (GHAT3) layers. In the α−T3 model, the AB-honeycomb lattice structure is supplemented with C atoms located… read more here.
