Criticality and entanglement in non-unitary quantum circuits and tensor networks of non-interacting fermions
Chao-Ming Jian, Bela Bauer, Anna Keselman +1
Models for non-unitary quantum dynamics, such as quantum circuits that include projective measurements, have been shown to exhibit rich quantum critical behavior. There are many co…

Scrambling and Lyapunov Exponent in Unitary Networks with Tunable Interactions
Anna Keselman, Laimei Nie, Erez Berg
Scrambling of information in a quantum many-body system, quantified by the out-of-time-ordered correlator (OTOC), is a key manifestation of quantum chaos. A regime of exponential g…

Dynamical signatures of quasiparticle interactions in quantum spin chains
Anna Keselman, Leon Balents, Oleg A. Starykh
We study the transverse dynamical susceptibility of an antiferromagnetic spin chain in presence of a longitudinal Zeeman field. In the low magnetization regime in the gapless…
