We present recent results from the Fastsum Collaboration, using anisotropic lattice QCD to study spectral properties of heavy quarkonia and open heavy flavour systems at high temperature. For heavy quarkonium, our results using a number of different methods suggest a small but …

We present nonperturbative results of the Casimir potential in non-Abelian SU(3) gauge theory in ( 2 + 1 ) D and ( 3 + 1 ) D in the confined and deconfined phase. For the first time, geometries beyond parallel plates in …

In this kick-off presentation for the "Recent developments in QCD" session at Baryons 2025 I will tie together the recent progress made on the extraction of parton distribution functions (PDFs) in lattice QCD and the long standing efforts in solving the inverse …

Variational principles play a central role in classical mechanics, providing compact formulations of dynamics and direct access to conserved quantities. While holonomic systems admit well-known action formulations, nonholonomic systems-subject to nonintegrable velocity constraints or position inequality constraints-have long resisted a general extremized …

This collection of Mathematica Notebooks contains the explicit implementation of the three example computations presented in "A variational approach to nonholonomic and inequality-constrained mechanics". The code demonstrates how three iconic model systems, the rolling-spinning disk, the particle in a tumbler and the …

The high-precision heavy quarkonium data from LHC Run 2 and the ongoing Run 3 provide a unique window into the properties of hot nuclear matter and the Quark-Gluon Plasma (QGP). To make full use of this data, it is crucial to go …

We demonstrate how observables with optimal sensitivity to environmental properties can be constructed explicitly from the master equation of an open quantum system. Our approach does not rely on the explicit solution of the master equation and instead expresses the symmetric logarithmic …
