Finite-temperature transport in the gapped spin-1/2 XXZ chain and one-dimensional lattice spinless fermion model
J. M. P. Carmelo, P. D. Sacramento
Here we consider a class of energy eigenstates of the spin-1/2 XXZ chain that exist both for anisotropies 1 and larger than 1. We show that at the isotropic point their contributio…
Diffusive charge transport in the gapped 1D Hubbard model at all finite temperatures
J. M. P. Carmelo, P. D. Sacramento
Studies relying on hydrodynamic theory and Kardar-Parisi-Zhang (KPZ) scaling have found that in the one-dimensional Hubbard model spin and charge transport are for all temperatures…
Ising spin-1/2 XXZ chain's quantum problems beyond the spinon paradigm
J. M. P. Carmelo, P. D. Sacramento
Spin chains are correlated quantum models of great interest in quantum systems and materials exhibiting quasi-one-dimensional magnetic properties. Here we review results on quantum…
Finite-temperature charge and spin transport in the one-dimensional Hubbard model accounting for its global [SU (2) X SU(2) X U(1)]/Z_2^2$ symmetry
J. M. P. Carmelo, J. E. C. Carmelo
Using a general representation that accounts for the effects on finite-temperature spin and charge transport of the global [SU (2) X SU(2) X U(1)]/(Z2 X Z2) symmetry of the one-dim…
Diffusive spin transport of the spin-1/2 XXZ chain in the Ising regime at zero magnetic field and finite temperature
Jose M. P. Carmelo, Pedro D. Sacramento
The studies of this paper on the spin-1/2 XXZ chain at finite temperatures T>0 have two complementary goals. The first is to identify the spin carriers of all its Sq>0 energy eigen…
Temperature dependence of charge transport in the half-filled 1D Hubbard model
J. M. P. Carmelo, P. D. Sacramento
The use of hydrodynamic transport theory seems to indicate that the charge diffusion constant D of the one-dimensional (1D) half-filled Hubbard model, whose Drude weight vanishes,…
