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…
Spatially Structured Entanglement from Nonequilibrium Thermal Pure States
Chen Bai, Mao Tian Tan, Bastien Lapierre +1
We study quantum quench dynamics in (1+1)-dimensional critical systems, starting from thermal pure states called crosscap states, and evolving them under spatially inhomogeneous Ha…
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…
Driven Non-Unitary Dynamics of Quantum Critical Systems
Bastien Lapierre, Pietro Pelliconi, Shinsei Ryu +1
We investigate the interplay between unitary and non-unitary driven many-body dynamics in (1+1)-dimensional quantum critical systems described by conformal field theory (CFT). By f…
Chiral Instabilities in Driven-Dissipative Quantum Liquids
Zhi-Xing Lin, Bastien Lapierre, Per Moosavi +1
We investigate the nonequilibrium dynamics of periodically driven Tomonaga-Luttinger liquids (TLLs) coupled to a thermal bath using a Floquet-Lindblad approach. When the coupling t…
Floquet engineered inhomogeneous quantum chaos in critical systems
Bastien Lapierre, Tokiro Numasawa, Titus Neupert +1
We study universal chaotic dynamics of a large class of periodically driven critical systems described by spatially inhomogeneous conformal field theories. By employing an effectiv…
Bridging two quantum quench problems -- local joining quantum quench and Möbius quench -- and their holographic dual descriptions
Jonah Kudler-Flam, Masahiro Nozaki, Tokiro Numasawa +2
We establish an equivalence between two different quantum quench problems, the joining local quantum quench and the Möbius quench, in the context of -dimensional conformal f…
Inhomogeneous Quantum Quenches of Conformal Field Theory with Boundaries
Xinyu Liu, Alexander McDonald, Tokiro Numasawa +2
We develop a method to calculate generic time-dependent correlation functions for inhomogeneous quantum quenches in (1+1)-dimensional conformal field theory (CFT) induced by sudden…
