Random physics

Work in collaboration with Kevissen Sellapillay and Laurent Raymond [arXiv:2501.05937]. Non-equilibrium entanglement transitions of a subsystem under discrete time dynamics.

Conference “chats2023” Trends in Hamiltonian systems, chaos and its applications, Luminy, Marseille 2023

On introduit quelques notions élémentaires de l’information quantique à partir d’un qubit.

We explore in these introductory notes, quantum phase transitions with a focus on dynamics.

Talk given at the Centre international de rencontres mathématiques, January 2020, on Quantum Walks and Computation

We explore in these introductory notes, the relation between information and physics through the investigation of the Maxwell demon paradox.

Quantum walk of two inteacting particles on a one dimensional lattice with an iterface at the origing separating two regions with different energy band topology.

We explore, using the interesting example of skyrmions in magnetic materials, some elementary concepts of topological phases in condensed matter. We proceed by traveling over different scales form macroscopic to microscopic and back.

Simple model of a complex quantum system: a particle interacting with spins on a graph.

We explore, using the interesting example of teleportation, some elementary concepts of quantum information, from quantum circuits to graphs states.
