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…
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…
Local-to-Global Entanglement Dynamics by Periodically Driving Impurities
Zhi-Xing Lin, Abhinav Prem, Shinsei Ryu +1
We study the entanglement dynamics of one-dimensional fermionic chains subject to a local Floquet drive of a two-site impurity, and uncover a sharp transition in the entanglement d…
Entanglement transitions in structured and random nonunitary Gaussian circuits
Bastien Lapierre, Liang-Hong Mo, Shinsei Ryu
We study measurement-induced phase transitions in quantum circuits consisting of kicked Ising models with postselected weak measurements, whose dynamics can be mapped onto a classi…
