Universal structure of measurement-induced information in many-body ground states
Zihan Cheng, Rui Wen, Sarang Gopalakrishnan +2
Unlike unitary dynamics, measurements of a subsystem can induce long-range entanglement via quantum teleportation. The amount of measurement-induced entanglement or mutual informat…
Generalized hydrodynamics: a perspective
Benjamin Doyon, Sarang Gopalakrishnan, Frederik Møller +2
Conventional hydrodynamics describes systems with few long-lived excitations. In one dimension, however, many experimentally relevant systems feature a large number of long-lived e…
Directly observing replica symmetry breaking in a vector quantum-optical spin glass
Ronen M. Kroeze, Brendan P. Marsh, David Atri Schuller +6
Spin glasses are quintessential examples of complex matter. Although much about their order remains uncertain, abstract models of them inform, e.g., the classification of combinato…
Observing quantum measurement collapse as a learnability phase transition
Utkarsh Agrawal, Javier Lopez-Piqueres, Romain Vasseur +2
The mechanism by which an effective macroscopic description of quantum measurement in terms of discrete, probabilistic collapse events emerges from the reversible microscopic dynam…
Extended critical phase in quasiperiodic quantum Hall systems
Jonas F Karcher, Romain Vasseur, Sarang Gopalakrishnan
We consider the effects of quasiperiodic spatial modulation on the quantum Hall plateau transition, by analyzing the Chalker-Coddington network model for the integer quantum Hall t…
Boundary transfer matrix spectrum of measurement-induced transitions
Abhishek Kumar, Kemal Aziz, Ahana Chakraborty +4
Measurement-induced phase transitions (MIPTs) are known to be described by non-unitary conformal field theories (CFTs) whose precise nature remains unknown. Most physical quantitie…
