Superfluidity in neutron stars and cold atoms [PDF]
, 2006 We discuss superfluidity in neutron matter, with particular attention to induced interactions and to universal properties accessible with cold atoms.Comment: 3 pages, 2 figures, talk at Quark Confinement and the Hadron Spectrum VII, Ponta Delgada ...

Multiple period states of the superfluid Fermi gas in an optical lattice
New Journal of Physics, 2016 We study multiple period states of a two-component unpolarized superfluid Fermi gas in an optical lattice along the Bardeen–Cooper–Schrieffer (BCS) to Bose–Einstein condensate (BEC) crossover.

Comment on ``Sound velocity and multibranch Bogoliubov spectrum of an elongated Fermi superfluid in the BEC-BCS crossover" [PDF]
, 2006 The work by T. K. Ghosh and K. Machida [cond-mat/0510160 and Phys. Rev. A 73, 013613 (2006)] on the sound velocity in a cylindrically confined Fermi superfluid obeying a power-law equation of state is shown to make use of an improper projection of the ...

Spin-orbit coupled repulsive Fermi atoms in a one-dimensional optical lattice
New Journal of Physics, 2015 Motivated by recent experimental development, we investigate spin–orbit coupled repulsive Fermi atoms in a one-dimensional optical lattice. Using the density-matrix renormalization group method, we calculate the momentum distribution function, gap, and ...

Fulde–Ferrell superfluids in spinless ultracold Fermi gases
New Journal of Physics, 2018 The Fulde–Ferrell (FF) superfluid phase, in which fermions form finite momentum Cooper pairings, is well studied in spin-singlet superfluids in past decades. Different from previous works that engineer the FF state in spinful cold atoms, we show that the

Synthetic topological Kondo insulator in a pumped optical cavity
New Journal of Physics, 2018 Motivated by experimental advances on ultracold atoms coupled to a pumped optical cavity, we propose a scheme for synthesizing and observing the Kondo insulator in Fermi gases trapped in optical lattices.

Multiplons in the two-hole excitation spectra of the one-dimensional Hubbard model
New Journal of Physics, 2016 Using the density-matrix renormalization group in combination with the Chebyshev polynomial expansion technique, we study the two-hole excitation spectrum of the one-dimensional Hubbard model in the entire filling range from the completely occupied band (

First and second sound of a unitary Fermi gas in highly oblate harmonic traps
New Journal of Physics, 2014 We theoretically investigate first and second sound modes of a unitary Fermi gas trapped in a highly oblate harmonic trap at finite temperatures. Following the idea by Stringari and co-workers (2010 Phys. Rev. Lett.

Realization of SU(2)*SU(6) Fermi System [PDF]
, 2010 We report the realization of a novel degenerate Fermi mixture with an SU(2)*SU(6) symmetry in a cold atomic gas. We successfully cool the mixture of the two fermionic isotopes of ytterbium 171Yb with the nuclear spin I=1/2 and 173Yb with I=5/2 below the ...

Virial expansion with Feynman diagrams
, 2011 We present a field theoretic method for the calculation of the second and third virial coefficients b2 and b3 of 2-species fermions interacting via a contact interaction. The method is mostly analytic. We find a closed expression for b3 in terms of the 2
