Gravity Analog Model of Non-equilibrium Thermodynamics
Noriaki Aibara, Naoaki Fujimoto, So Katagiri +4
Non-equilibrium thermodynamics of Onsager and Machlup and of Hashitsume is reformulated as a gravity analog model, in which thermodynamic variables, kinetic coefficients and genera…
Phase diagram of a generalized Hubbard model applied to orbital order in manganites
Qingshan Yuan, Takashi Yamamoto, Peter Thalmeier
The magnetic phase diagram of a two-dimensional generalized Hubbard model proposed for manganites is studied within Hartree-Fock approximation. In this model the hopping matrix inc…
Exact Dynamics of the SU(K) Haldane-Shastry Model
Takashi Yamamoto, Yasuhiro Saiga, Mitsuhiro Arikawa +1
The dynamical structure factor of the SU(K) (K=2,3,4) Haldane-Shastry model is derived exactly at zero temperature for arbitrary size of the system. The result is interpre…
Exact dynamical structure factor of the degenerate Haldane-Shastry model
Takashi Yamamoto, Yasuhiro Saiga, Mitsuhiro Arikawa +1
The dynamical structure factor of the K-component (K = 2,3,4) spin chain with the 1/r^2 exchange is derived exactly at zero temperature for arbitrary size of the system. T…
Dynamical correlation functions of the spin Calogero-Sutherland model
Takashi Yamamoto, Mitsuhiro Arikawa
The thermodynamic limit of the dynamical density and spin-density two-point correlation functions for the spin Calogero-Sutherland model are derived from Uglov's finite-size result…
Exact Charge Dynamics in the Supersymmetric t-J Model with Inverse-Square Interaction
Mitsuhiro Arikawa, Takashi Yamamoto, Yasuhiro Saiga +1
Dynamical charge structure factor with smaller than the Fermi wave number is derived analytically for the one-dimensional supersymmetric t-J model with interac…
