Enhanced Quantum Reflection of Matter-Wave Solitons
Chaohong Lee, Joachim Brand
Matter-wave bright solitons are predicted to reflect from a purely attractive potential well although they are macroscopic objects with classical particle-like properties. The non-…
Quantum Computation with Diatomic Bits in Optical Lattices
Chaohong Lee, Elena A. Ostrovskaya
We propose a scheme for scalable and universal quantum computation using diatomic bits with conditional dipole-dipole interaction, trapped within an optical lattice. The qubit stat…
Bose-Einstein Condensation of Particle-Hole Pairs in Ultracold Fermionic Atoms Trapped within Optical Lattices
Chaohong Lee
We investigate the Bose-Einstein condensation (BEC, superfluidity) of particle-hole pairs in ultracold Fermionic atoms with repulsive interactionsand arbitrary polarization, which…
Phase-Dependent Spontaneous Spin Polarization and Bifurcation Delay in Coupled Two-Component Bose-Einstein Condensates
Chaohong Lee, Wenhua Hai, Lei Shi +1
The spontaneous spin polarization and bifurcation delay in two-component Bose-Einstein condensates coupled with laser or/and radio-frequency pulses are investigated. We find that t…
Conditional Spontaneous Spin Polarization and Bifurcation Delay in Coupled Two-Component Bose-Einstein Condensates
Chaohong Lee, Wenhua Hai, Lei Shi +1
The spontaneous spin polarization and bifurcation delay in two-component Bose-Einstein condensates coupled with Raman pulses are investigated. We find that the bifurcation and the…
Quasi-spin Model for Macroscopic Quantum Tunnelling between Two Coupled Bose-Einstein Condensates
Chaohong Lee, Wenhua Hai, Xueli Luo +2
The macroscopic quantum tunneling between two coupled Bose-Einstein condensates (BEC) (radio-frequency coupled two-component BECs or two BECs confined in a double-well potential) i…
