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…
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…
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…
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…
Thermal and dissipative effects on the heating transition in a driven critical system
Kenny Choo, Bastien Lapierre, Clemens Kuhlenkamp +3
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…
The fine structure of heating in a quasiperiodically driven critical quantum system
Bastien Lapierre, Kenny Choo, Apoorv Tiwari +3
We study the heating dynamics of a generic one dimensional critical system when driven quasiperiodically. Specifically, we consider a Fibonacci drive sequence comprising the Hamilt…
Emergent Black Hole Dynamics in Critical Floquet Systems
Bastien Lapierre, Kenny Choo, Clément Tauber +3
While driven interacting quantum matter is generically subject to heating and scrambling, certain classes of systems evade this paradigm. We study such an exceptional class in peri…
