Spin singlet-triplet transition in a Si-based two-electron double quantum dot molecule
S. D. Lee, S. J. Kim, J. S. Kang +6
We report a successful measurement of the magnetic field-induced spin singlet-triplet transition in silicon-based coupled dot systems. Our specific experimental scheme incorporates…

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…

Occupation Numbers of a Half-Filled Landau Level
J. H. Han, S. -R. Eric Yang
We demonstrate that a theory of the edge of a half-filled Landau level recently proposed by Lee and Wen predicts results for the edge occupation number similar to those of a variat…
