Contraction of fermionic operator circuits and the simulation of strongly correlated fermions
Thomas Barthel, Carlos Pineda, Jens Eisert
A fermionic operator circuit is a product of fermionic operators of usually different and partially overlapping support. Further elements of fermionic operator circuits (FOCs) are…
Unitary circuits for strongly correlated fermions
C. Pineda, T. Barthel, J. Eisert
We introduce a scheme for efficiently describing pure states of strongly correlated fermions in higher dimensions using unitary circuits featuring a causal cone. A local way of com…
Spectral functions in one-dimensional quantum systems at T>0
Thomas Barthel, Ulrich Schollwöck, Steven R. White
We present for the first time time-dependent density-matrix renormalization-group simulations (t-DMRG) at finite temperatures. It is demonstrated how a combination of finite-temper…
