Spin crossovers and superdiffusion in the one-dimensional Hubbard model
Michele Fava, Brayden Ware, Sarang Gopalakrishnan +2
We use tools from integrability and generalized hydrodynamics to study finite-temperature dynamics in the one-dimensional Hubbard model. First, we examine charge, spin, and energy…
Mean-field entanglement transitions in random tree tensor networks
Javier Lopez-Piqueres, Brayden Ware, Romain Vasseur
Entanglement phase transitions in quantum chaotic systems subject to projective measurements and in random tensor networks have emerged as a new class of critical points separating…
Anomalous low-frequency conductivity in easy-plane XXZ spin chains
Utkarsh Agrawal, Sarang Gopalakrishnan, Romain Vasseur +1
In the easy-plane regime of XXZ spin chains, spin transport is ballistic, with a Drude weight that has a discontinuous fractal dependence on the value of the anisotropy $Δ= \cos πλ…
Anomalous relaxation and the high-temperature structure factor of XXZ spin chains
Sarang Gopalakrishnan, Romain Vasseur, Brayden Ware
We compute the spin structure factor of XXZ spin chains in the Heisenberg and gapped (Ising) regimes in the high-temperature limit for nonzero magnetization, within the framework o…
