This talk reviews some recent progress in making sense of confinement. The focus of the talk is on cousins of QCD, rather than QCD itself; these cousin theories have features lacking in QCD which facilitate the analysis. One critical feature of this sort is center symmetry, and the core of the talk is an exploration of the connection of center symmetry to confinement. One principal way to...

Lattice QCD simulations tend to become stuck in a single topological sector at fine lattice spacing, or when using chirally symmetric overlap quarks. In such cases computed observables differ from their full QCD counterparts by finite volume corrections, which need to be understood on a quantitative level. We discuss extensions of existing relations from the literature between correlation...

Saturation of gluon distribution is a consequence of non-linear evolution equations of QCD. Saturation implies the existence of so called saturation momentum which is gluon density per unit rapidity per transverse area. At large energies for certain kinematical domains saturation momentum is the only scale for physical processes. As a consequence different observables exhibit so called...

Simulations with a finite chemical potential typically lead to a severe sign problem, prohibiting any standard Monte Carlo approach. For simulations of QCD we use the complex Langevin method, for which we apply adaptive step-sizes and gauge cooling to ensure the convergence. We present preliminary results for heavy quark QCD and explore the application for two dynamical quarks.
