2226. Vortices and the fine structure of quantum light-cones (G)*

Oral Competition (Graduate Student) / Compétition orale (Étudiant(e) du 2e ou 3e cycle)

We identify the light-cone-like structures present following quenches in spin-chains as quantum caustics. These are discrete versions of the singularities classified by catastrophe theory. From this identification follows: local universality

2231. Thermalization by Rapid Bombardment (G)*

Imagine a quantum system placed within a thermal gas, which is itself composed of many quantum systems e.g. atoms/molecules. As the constituents of the environment scatter off of the system, it is natural to expect that the system will reach a thermal equilibrium with its environment. Moreover one may expect that the ultimate thermalization of the system is largely independent of the coupling...

2236. Gravity in quantum systems: lessons from spectroscopy

Dr Rob Scott (University of Brest)

Theoretical Physics / Physique théorique (DTP-DPT)

Oral (Non-Student) / Orale (non-étudiant(e))

The goal of this project is to make progress in quantum gravity by studying gravity in quantum mechanical systems at atomic scales. We compare approaches to the generation of gravitational waves and gravitons from quantum mechanical systems such as the ammonia molecule. The approach is guided by the strong analogy between classical electromagnetism and classical general relativity. We evaluate...

2355. Modification of Landau levels and degeneracy due to a parallel linear electric field

Oral Competition (Graduate Student) / Compétition orale (Étudiant(e) du 2e ou 3e cycle)

When a charged particle moves in a plane perpendicular to a constant magnetic field (z-direction) the discrete energy levels are called Landau levels. The energies resemble those of the harmonic oscillator with $\omega$ the cyclotron frequency $\omega_c$. The energies are highly degenerate, with the degeneracy being independent of the energy. We now add a linear electric field parallel to the...
