Ground-state reference systems for expanding correlated fermions in one dimension
F. Heidrich-Meisner, M. Rigol, A. Muramatsu +2
We study the sudden expansion of strongly correlated fermions in a one-dimensional lattice, utilizing the time-dependent density-matrix renormalization group method. Our focus is o…

Drude weight in systems with open boundary conditions
Marcos Rigol, B. Sriram Shastry
For finite systems, the real part of the conductivity is usually decomposed as the sum of a zero frequency delta peak and a finite frequency regular part. In studies with periodic…
