Critical quench dynamics of random quantum spin chains: ultra-slow relaxation from initial order and delayed ordering from initial disorder
By means of free fermionic techniques combined with multiple precision arithmetic we study the time evolution of the average magnetization, $\overline{m}(t)$ , of the random transverse-field Ising chain after global quenches. We observe different relaxation behaviors for quenches starting from diffe...
