Candidate source of flux noise in SQUIDs: adsorbed oxygen molecules
Hui Wang, Chuntai Shi, Jun Hu +3
A major obstacle to using SQUIDs as qubits is flux noise. We propose that the heretofore mysterious spins producing flux noise could be molecules adsorbed on the surface. Usi…
Unconventional superconducting phases on a two-dimensional extended Hubbard model
Wen-Min Huang, Chen-Yen Lai, Chuntai Shi +1
We study the phase diagram of the extended Hubbard model on a two-dimensional square lattice, including on-site (U) and nearest-neighbor (V) interactions, at weak couplings. We sho…
Correlated Phases of Population Imbalanced Fermi-Fermi Mixtures on an Optical Lattice
Chen-Yen Lai, Chuntai Shi, Shan-Wen Tsai
We study a two species fermion mixture with different populations on a square lattice modeled by a Hubbard Hamiltonian with on-site inter-species repulsive interaction. Such a mode…
Proximity-induced superconductivity in nanowires: Mini-gap state and differential magnetoresistance oscillations
Jian Wang, Chuntai Shi, Mingliang Tian +5
We study proximity-induced superconductivity in gold nanowires as a function of the length of the nanowire, magnetic field, and excitation current. Short nanowires exhibit a sharp…
States of interacting composite fermions at Landau level fillig
Csaba Toke, Chuntai Shi, Jainendra K. Jain
There is increasing experimental evidence for fractional quantum Hall effect at filling factor . Modeling it as a system of composite fermions, we study the problem of int…
Resonant tunneling in fractional quantum Hall effect: superperiods and braiding statistics
Jainendra K. Jain, Chuntai Shi
We study theoretically resonant tunneling of composite fermions through their quasi-bound states around a fractional quantum Hall island, and find a rich set of possible transition…
