Description
Simulating quantum systems in a finite volume is a powerful theoretical tool for extracting information about them. The observation that the real-world properties of states are encoded in how their discrete energy levels change with the size of the volume gives rise to a versatile formalism that is relevant not only for nuclear physics, but also for other fields such as simulations of cold atomic systems.
This talk gives an overview of recent progress that has been achieved in the field of finite-volume few-body physics, covering in particular systems of charged particles and resonance states. Characterized by being strongly coupled to the continuum, resonances are notoriously challenging to describe theoretically and to compute numerically, especially when they appear as genuine few-body phenomena. As this talk will show, finite periodic boxes allow for an elegant implementation of the non-Hermitian quantum mechanical framework that gives direct access to the properties of few-body resonance states, leading to various applications and inspirations for other techniques.
