During a quantum measurement, superpositions of states with different observable properties probabilistically collapse into one with a sharp value of the measured observable. In macroscopic quantum systems, this collapse arises via a continuous measu

Les théories des champs conformes logarithmiques (LCFTs) sont cruciales pour décrire le comportement critique de systèmes physiques variés: les transitions de phase dans les systèmes électroniques désordonnés sans interaction (comme par exemp

Quasiperiodic systems share features with disordered models but their underlying determinism give them distinct behaviour. Here the authors study the critical behaviour of quasiperiodic spin models and show that the renormalization group fixed points

Monitored quantum circuits can exhibit an entanglement transition as a function of the rate of measurements, stemming from the competition between scrambling unitary dynamics and disentangling projective measurements. We study how entanglement dynami

Anomalous finite-temperature transport has recently been observed in numerical studies of various integrable models in one dimension; these models share the feature of being invariant under a continuous non-Abelian global symmetry. This work offers a

We address the critical properties of the many-body localization (MBL) phase transition in one-dimensional systems subject to spatially correlated disorder. We consider a general family of disorder models, parameterized by how strong the fluctuations

We consider monitored quantum systems with a global conserved charge, and ask how efficiently an observer ("eavesdropper") can learn the global charge of such systems from local projective measurements. We find phase transitions as a function of the
