Theoretical Physics

项目介绍

KU Leuven Kulak’s Science & Technology group provides education in a wide range of undergraduate science programs (as well as transition options to (bio-)engineering and pharmacy), while also making the link to contemporary research. Within the S&T Kulak group, the research group “(Quantum) Gauge Theories” focusses on Quantum Chromodynamics and Classical Electrodynamics. This takes us from the smallest nuclear building blocks to model building for non-destructive monitoring in geophysics.Website unit

Project

We will investigate the formation of the QCD flux tube (confining string) between 2 static charges (quark and anti-quark) in terms of the Casimir force. The latter is a famous consequence of the non-emptiness of the quantum vacuum, with experimental verification in the QED, aka quantum electrodynamics, case: 2 parallel (uncharged) plates undergo a net force due to the quantized electromagnetic field. In the case of QCD, aka quantum chromodynamics, which handles the strong nuclear (color) force, the Casimir force is far less understood. Our working hypothesis is that in the non-perturbative QCD vacuum, the Casimir effect favours the formation of an energetically stable 3D cylinder-shape between the boundary charges, embedded in the normal vacuum. Inspiration is drawn from the “old” nucleonic bag models. We will develop our new methodology for the non-Abelian gauge theory in (2+1)-dimensions, where the cylinder becomes a rectangle, making the computations somewhat easier. A first novelty in our approach will come from QCD vacuum effects encoded by a non-perturbative path integration scheme, viz. the Gribov-Zwanziger approach. The associated mass gap equation will have an interesting interplay with the geometric cylinder/rectangle parameters and thence can drive the tube formation. A second novelty will be the inclusion of boundary charges in a gauge invariant fashion via non-local, dressed field configurations. Finally, we will probe the melting properties of the tube if the temperature is switched on, in search of a fresh perspective on the deconfinement phase transition.

This internationally oriented PhD project will happen in close collaboration with colleagues from Universitá di Napoli Federico II (Italië), Centro de Estudios Científicos (CECs, Valdivia, Chili) en Duy Tân University (Da Nang, Vietnam).
Next to the research activities, the candidate will also become part of the assisting educational team in the Bachelor programmes of campus Kulak (Kortrijk).
