Dynamical conductivity of disordered quantum chains
Shintaro Takayoshi, Thierry Giamarchi
We study the transport properties of a one dimensional quantum system with disorder. We numerically compute the frequency dependence of the conductivity of a fermionic chain with n…

Spontaneous population imbalance in two-component Bose and Fermi gases
Shintaro Takayoshi, Masahiro Sato, Shunsuke Furukawa
We study two-component (or pseudo-spin-1/2) Bose or Fermi gases in one dimension, in which particles are convertible between the components. Through bosonization and numerical anal…
