Job Description
Thesis Subject
Topological phases constitute a class of quantum states that exhibit global properties robust against defects and perturbations. Althoughoften associated with exotic materials such as topological insulators, these phases can also emerge in periodically driven systems (Floquetsystems), providing an ideal framework for studying out-of-equilibrium topology.
This thesis will focus on the numerical study and experimental realization of a topological model using a Bose–Einstein condensate (BEC)of potassium subjected to periodic light pulses, inspired by the paradigm of the quantum kicked rotor. The project will build on a schemerecently demonstrated by the team, combining spin-dependent optical potentials and modulated Raman coupling to induce an effectivespin–orbit coupling.
The main objective will be to identify and characterize signatures of topological phases, such as transitions between localized anddelocalized states or the emergence of topological invariants in the quasi-energy spectrum. The work will include participation in thePhLAM's BEC experiments, analysis of atomic dynamics, and the development of numerical simulations in connection with theoreticalcollaborations.
Your Work Environment
The experimental work will be carried out on a potassium Bose-Einstein condensation apparatus at the PhLAM laboratory, under the supervision of Radu Chicireanu.
