Operator-space fragmentation and integrability in Pauli-Lindblad models
Dawid Paszko, Christopher J. Turner, Dominic C. Rose +1
The Lindblad equation for open quantum systems is central to our understanding of coherence and entanglement in the presence of Markovian dissipation. In closed quantum systems Hil…

Exact generalized Bethe eigenstates of the non-integrable alternating Heisenberg chain
Ronald Melendrez, Bhaskar Mukherjee, Marcin Szyniszewski +3
Exact solutions of quantum lattice models serve as useful guides for interpreting physical phenomena in condensed matter systems. Prominent examples of integrability appear in one…

Measurement-induced Lévy flights of quantum information
Igor Poboiko, Marcin Szyniszewski, Christopher J. Turner +3
We explore a model of free fermions in one dimension, subject to frustrated (non-commuting) local measurements across adjacent sites, which resolves the fermions into non-orthogona…
