Real-time and real-space spin- and energy dynamics in one-dimensional spin-1/2 systems induced by local quantum quenches at finite temperatures
C. Karrasch, J. E. Moore, F. Heidrich-Meisner
We study the spin- and energy dynamics in one-dimensional spin-1/2 systems induced by local quantum quenches at finite temperatures using a time-dependent density matrix renormaliz…

Dynamical phase transitions after quenches in non-integrable models
C. Karrasch, D. Schuricht
We investigate the dynamics following sudden quenches across quantum critical points belonging to different universality classes. Specifically, we use matrix product state methods…

The Drude weight of the spin-1/2 XXZ chain: density matrix renormalization group versus exact diagonalization
C. Karrasch, J. Hauschild, S. Langer +1
We revisit the problem of the spin Drude weight D of the integrable spin-1/2 XXZ chain using two complementrary approaches, exact diagonalization (ED) and the time-dependent densit…
