Equivalence of transport coefficients in bath-induced and dynamical scenarios
Robin Steinigeweg, Marcel Ogiewa, Jochen Gemmer
We investigate the transport of a single excitation through a chain of weakly coupled subunits. At both ends the chain is exposed to baths which are incorporated by means of a mast…
Projection operator approach to transport in complex single-particle quantum systems
Robin Steinigeweg, Jochen Gemmer, Heinz-Peter Breuer +1
We discuss the time-convolutionless (TCL) projection operator approach to transport in closed quantum systems. The projection onto local densities of quantities such as energy, mag…
A real-time study of diffusive and ballistic transport in spin-1/2 chains using the adaptive time-dependent density matrix renormalization group method
S. Langer, F. Heidrich-Meisner, J. Gemmer +2
Using the adaptive time-dependent density matrix renormalization group method, we numerically study the spin dynamics and transport in one-dimensional spin-1/2 systems at zero temp…
