Dissipation-enhanced scrambling in the SYK model coupled to a lossy cavity
Pietro Pelliconi, Bastien Lapierre, Shinsei Ryu
We study the Yukawa-Sachdev-Ye-Kitaev model, a disordered model of Majorana fermions and bosons in which the bosons are linearly coupled to independent realizations of S…
Anomalous entanglement scaling from eigenvector nonorthogonality in critical non-Hermitian free fermions
Zhenyu Xiao, Shinsei Ryu
Entanglement carries universal content that labels phases and critical points. We study the entanglement entropy of the steady states of critical non-Hermitian free-fermion chains.…
Diffusive Dynamics of Nonstabilizerness
Zhenyu Xiao, Shinsei Ryu
Symmetries shape the quantum-information dynamics of many-body systems, but their effect on nonstabilizerness, the resource complementary to entanglement, is less understood. We co…
Bootstrapping Symmetries in Quantum Many-Body Systems from the Cross Spectral Form Factor
Chen Bai, Zihan Zhou, Bastien Lapierre +1
Symmetries play a central role in quantum many-body physics, yet uncovering them systematically remains challenging. We introduce a bootstrap framework to reconstruct the represent…
Non-Hermitian Disordered Systems
Kohei Kawabata, Shinsei Ryu
Non-Hermitian disordered systems have emerged as a central arena in modern physics, with ramifications spanning condensed matter, quantum, statistical, and high energy contexts. Th…
