Bose-Einstein condensate of two-dimensional excitons in a ring: Necklace-like modulation of order parameter
S. -R. Eric Yang, Q-Han Park, J. Yeo
We have studied theoretically the Bose-Einstein condensation (BEC) of two-dimensional excitons in a ring with small random width variation. We derive a nonlinear Gross-Pitaevkii eq…

Non-commutative field theory approach to two-dimensional vortex liquid system
Kyungsun Moon, Vincent Pasquier, Chaiho Rim +1
We investigate the non-commutative (NC) field theory approach to the vortex liquid system restricted to the lowest Landau level (LLL) approximation. NC field theory effectively tak…
