Spin, charge and -spin separation in one-dimensional photo-doped Mott insulators
Yuta Murakami, Shintaro Takayoshi, Tatsuya Kaneko +2
We show that effectively cold metastable states in one-dimensional photo-doped Mott insulators described by the extended Hubbard model exhibit spin, charge and -spin separation.…
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…
Second-order magnetic responses in quantum magnets: Magnetization under ac magnetic fields
Tatsuya Kaneko, Yuta Murakami, Shintaro Takayoshi +1
We investigate second-order magnetic responses of quantum magnets against ac magnetic fields. We focus on the case where the component of the spin is conserved in the unperturb…
