Composite symmetry protected topological order and effective models
A. Nietner, C. Krumnow, E. J. Bergholtz +1
Strongly correlated quantum many-body systems at low dimension exhibit a wealth of phenomena, ranging from features of geometric frustration to signatures of symmetry-protected top…
Diagnosing Topological Edge States via Entanglement Monogamy
Konstantinos Meichanetzidis, Jens Eisert, Mauro Cirio +2
Topological phases of matter possess intricate correlation patterns typically probed by entanglement entropies or entanglement spectra. In this work, we propose an alternative appr…
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…
