Spin rotation invariant spin triplet superconducting liquids
Fei Zhou
Spin ordering and its effect on the low energy quasiparticles in a p-wave superconducting fluid are investigated. We study the properties of a new 2D quantum spin triplet supercond…
Hidden topological order in Bose-Einstein Condensates
Fei Zhou
We show the existence of a new hidden topological order in (F=1) Bose-Einstein condensates (BEC) with antiferromagnetic interactions. Occurrence of this order is due to t…
Spin-1/2 Collective Excitations in BEC of Interacting Spin-1 Atoms
Fei Zhou
We construct spin-1/2 collective excitations in BEC of interacting spin-1 atoms. These excitations exist in states with a maximal global degeneracy. The stability and energy of the…
Wave Function Mismatches and Coulomb Drag
Fei Zhou
In this paper, I study the topological excitations in a pairing state in double layer systems at Landau level filling factor in the presence of disorders. Due to mismatches…
Mesoscopic coherence effect in superconductor-metallic ferromagnet structures
Fei Zhou, Boris Spivak
The boundary condition in Eq.6 is invalid.
Quantum Phase Pumping
Fei Zhou
In this Letter, we consider the adiabatic charge transport through a normal mesoscopic sample sandwiched by superconductors without modulation of local chemical potentials. The def…
