Geometry of Noisy Quantum Many-Body Dynamics with Continuous Symmetries: Entanglement and Correlations
Marco Lastres, Sanjay Moudgalya
We study unitary quantum dynamics in noisy Brownian models with global continuous symmetries, such as and , focusing on Rényi entanglement entropies and hydrodynamic…

Geometry of Free Fermion Commutants
Marco Lastres, Sanjay Moudgalya
Understanding the structure of operators that commute with identical replicas of unitary ensembles, also known as their -commutants, is an important problem in quantum many-…

Non-Universality from Conserved Superoperators in Unitary Circuits
Marco Lastres, Frank Pollmann, Sanjay Moudgalya
An important result in the theory of quantum control is the "universality" of -local unitary gates, i.e. the fact that any global unitary evolution of a system of qudits can…
