Phase transitions in coupled Ising chains and SO()-symmetric spin chains
Yohei Fuji, Sylvain Capponi, Lukas Devos +1
The paper studies quantum phase transitions in a one‑dimensional system made of multiple coupled Ising chains, showing that for two or three chains the transition is continuous (Is…
An introduction to monitored quantum systems and quantum trajectories: spectrum, typicality, and phases
Ryusuke Hamazaki, Ken Mochizuki, Hisanori Oshima +1
Thanks to recent experimental advances in simulating and detecting quantum dynamics with high precision and controllability, our understanding of the physics of monitored quantum s…
Topology and Spectrum in Measurement-Induced Phase Transitions
Hisanori Oshima, Ken Mochizuki, Ryusuke Hamazaki +1
Competition among repetitive measurements of noncommuting observables and unitary dynamics can give rise to a wide variety of entanglement phases. Here, we propose a general framew…
Floquet Flux Attachment in Cold Atomic Systems
Helia Kamal, Jack Kemp, Yin-Chen He +4
Flux attachment provides a powerful conceptual framework for understanding certain forms of topological order, including most notably the fractional quantum Hall effect. Despite it…
Multifractality in monitored single-particle dynamics
Kohei Yajima, Hisanori Oshima, Ken Mochizuki +1
We study multifractal properties in time evolution of a single particle subject to repeated measurements. For quantum systems, we consider circuit models consisting of local unitar…
