Strong correlation effects in 2D Bose–Einstein condensed dipolar excitons

Bose-einstein Condensation of Excitons in Ideal 2d System in Strong Magnetic Field

We study ideal two-dimensional ( 2D ) electron-hole system in a strong perpendicular magnetic field using the Keldysh-Kozlov-Kopaev method and generalized random phase approximation. The Bose-Einstein condensation of the correlated pairs takes place on a single particle state with an arbitrary wave vector k in a symmetric 2D model. We show that the ground state energy per one exciton and the ch...

Dipolar Interaction in 2d Honeycomb Magnets

The classical ground state of a system of dipoles arranged on a 2D honeycomb lattice is rigorously shown to be a (1/3,−1/3) structure. This configuration exhibits a continuous degeneracy with respect to rotations of the two hexagonal sublattices in opposite directions. These results are in agreement with observations on ErBr3, suggesting that dipolar interactions are dominant in the latter comp...
