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…
Emergent Self-Similar Quantum Revivals in Spiral Drives
Xin-Chi Zhou, Liang-Hong Mo, Hongzheng Zhao +1
We uncover a distinct form of nonequilibrium temporal order: self-similar quantum revivals in a many-body system driven by quasiperiodic spiral kicks, where the system recurrently…
Observing Conformal Floquet Dynamics on a Digital Quantum Processor
Liang-Hong Mo, Bastien Lapierre, Qiang Miao
Quantum simulations are traditionally confined to exploring dynamics starting from unentangled or low-entanglement states due to severe bottlenecks in protocol design, hardware per…
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…
Observing quantum many-body dynamics in emergent curved spacetime using programmable quantum processors
Brendan Rhyno, Bastien Lapierre, Smitha Vishveshwara +2
We digitally simulate quantum many-body dynamics in emergent curved backgrounds using 80 superconducting qubits on IBM Heron processors. By engineering spatially varying couplings…
Nonequilibrium Probes of Quantum Geometry in Gapless Systems
Bastien Lapierre, Per Moosavi, Blagoje Oblak
Much of our understanding of gapless quantum matter stems from low-energy descriptions using conformal field theory. This is especially true in 1+1 dimensions, where such theories…
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…
Quantum Hall edges beyond the plasma analogy
Per Moosavi, Blagoje Oblak, Bastien Lapierre +2
We demonstrate that the widely used plasma analogy is unreliable at predicting edge properties of quantum Hall states. This discrepancy arises from a fundamental difference between…
Topology of ultra-localized insulators and superconductors
Bastien Lapierre, Luka Trifunovic, Titus Neupert +1
The topology of an insulator can be defined even when all eigenstates of the system are localized - an extreme case of Anderson insulators that we call ultra-localized. We derive t…

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…

We study two-dimensional (2D) droplets of noninteracting electrons in a strong magnetic field, placed in a confining potential with arbitrary shape. Using semiclassical methods ada…
Probing Chern number by opacity and topological phase transition by a nonlocal Chern marker
Paolo Molignini, Bastien Lapierre, R. Chitra +1
In 2D semiconductors and insulators, the Chern number of the valence band Bloch state is an important quantity that has been linked to various material properties, such as the topo…
Marginal quenches and drives in Tomonaga-Luttinger liquids
Shouvik Datta, Bastien Lapierre, Per Moosavi +1
We study Tomonaga-Luttinger liquids thrown out of equilibrium by marginal deformations in the form of interaction modulations. This is modeled by quenching or periodically driving…

We study the dissipative dynamics of a periodically driven inhomogeneous critical lattice model in one dimension. The closed system dynamics starting from pure initial states is we…
Topologically localized insulators
Bastien Lapierre, Titus Neupert, Luka Trifunovic
We show that fully-localized, three-dimensional, time-reversal-symmetry-broken insulators do not belong to a single phase of matter but can realize topologically distinct phases th…
-band Hopf insulator
Bastien Lapierre, Titus Neupert, Luka Trifunovic
We study the generalization of the three-dimensional two-band Hopf insulator to the case of many bands, where all the bands are separated from each other by band gaps. The obtained…
