Finite temperature spin diffusion in the Hubbard model in the strong coupling limit
Oleksandr Gamayun, Arthur Hutsalyuk, Balázs Pozsgay +1
We investigate finite temperature spin transport in one spatial dimension by considering the spin-spin correlation function of the Hubbard model in the limiting case of infinitely…
Thermodynamics of the Spin Luttinger-Liquid in a Model Ladder Material
Ch. Rüegg, K. Kiefer, B. Thielemann +11
The phase diagram in temperature and magnetic field of the metal-organic, two-leg, spin-ladder compound (C5H12N)2CuBr4 is studied by measurements of the specific heat and the magne…
One-particle irreducible density matrix for the spin disordered infinite Hubbard chain
Vadim V. Cheianov, M. B. Zvonarev
In this Letter we present a calculation of the one-particle irreducible density matrix for the one-dimensional (1D) Hubbard model in the infinite limit. We consider the…
Zero temperature correlation functions for the impenetrable fermion gas
Vadim V Cheianov, M B Zvonarev
We calculate the long time and distance asymptotics of the one-particle correlation functions in the model of impenetrable spin 1/2 fermions in 1+1 dimensions. We consider the spin…
Non-Unitary Spin-Charge Separation in One-Dimensional Fermion Gas
Vadim V. Cheianov, M. B. Zvonarev
In this Letter we report exact results on the infrared asymptotics of one-particle dynamical correlation function of the gas of impenetrable spin 1/2 fermions at infinitesimal temp…
