Many-body localization in infinite chains
Many-body localization in infinite chains
We investigate the phase transition between an ergodic and a many-body localized phase in infinite anisotropic spin-$1/2$ Heisenberg chains with binary disorder. Starting from the N\'eel state, we analyze the decay of antiferromagnetic order ${m}_{s}(t)$ and the growth of entanglement entropy ${S}_{\mathrm{ent}}(t)$ during unitary time evolution. Near the phase transition …
