Flow-Induced Charge Modulation in Superfluid Atomic Fermions Loaded into an Optical Kagome Lattice
Daisuke Yamamoto, Chika Sato, Tetsuro Nikuni +1
We study the superfluid state of atomic fermions in a tunable optical kagome lattice motivated by recent experiments. We show that imposed superflow induces spatial modulations in…
Coexistence of superfluid gap and pseudogap in the BCS-BEC crossover regime of a trapped Fermi gas below
Ryota Watanabe, Shunji Tsuchiya, Yoji Ohashi
We investigate strong pairing fluctuations and effects of a harmonic trap in the superfluid phase of an ultracold Fermi gas. Including amplitude and phase fluctuations of the inhom…
Two-dimensional pseudogap effects of an ultracold Fermi gas in the BCS-BEC crossover region
Ryota Watanabe, Shunji Tsuchiya, Yoji Ohashi
We investigate pseudogap phenomena originating from pairing fluctuations in the BCS-BEC crossover regime of a two-dimensional Fermi gas in a harmonic trap. Including pairing fluctu…
Superfluidity of Dirac Fermions in a Tunable Honeycomb Lattice: Cooper Pairing, Collective Modes, and Critical Currents
Shunji Tsuchiya, R. Ganesh, Arun Paramekanti
Motivated by recent experiments on atomic Dirac fermions in a tunable honeycomb optical lattice, we study the attractive Hubbard model of superfluidity in the anisotropic honeycomb…
Fermionic solutions of chiral Gross-Neveu and Bogoliubov-de Gennes systems in nonlinear Schrödinger hierarchy
Daisuke A. Takahashi, Shunji Tsuchiya, Ryosuke Yoshii +1
The chiral Gross-Neveu model or equivalently the linearized Bogoliubov-de Gennes equation has been mapped to the nonlinear Schrödinger (NLS) hierarchy in the Ablowitz-Kaup-Newell-S…
