A Universal Operator Growth Hypothesis
Daniel E. Parker, Xiangyu Cao, Alexander Avdoshkin +2
We present a hypothesis for the universal properties of operators evolving under Hamiltonian dynamics in many-body systems. The hypothesis states that successive Lanczos coefficien…
Entanglement in a fermion chain under continuous monitoring
Xiangyu Cao, Antoine Tilloy, Andrea De Luca
We study the entanglement entropy of the quantum trajectories of a free fermion chain under continuous monitoring of local occupation numbers. We propose a simple theory for entang…
Operator Product Expansion in Liouville Field Theory and Seiberg type transitions in log-correlated Random Energy Models
Xiangyu Cao, Pierre Le Doussal, Alberto Rosso +1
We study transitions in log-correlated Random Energy Models (logREMs) that are related to the violation of a Seiberg bound in Liouville field theory (LFT): the binding transition a…
Pinning by rare defects and effective mobility for elastic interfaces in high dimensions
Xiangyu Cao, Vincent Démery, Alberto Rosso
The existence of a depinning transition for a high dimensional interface in a weakly disordered medium is controversial. Following Larkin arguments and a perturbative expansion, on…
