Centre vortex structure of QCD-vacuum fields and confinement
The non-trivial ground-state vacuum fields of QCD form the foundation of matter. Using modern visualisation techniques, this presentation examines the microscopic structure of these fields.

Confinement and vacuum structure in compact QED on the lattice
Abstract Using an effective action and assuming that the physical ground state has no structure, we demonstrate that the spectrum of the compact U(1) gauge model has massless (vector and scalar) bosons.

Confinement, vacuum structure: from QCD to quantum gravity [PDF]
A minimal Lorentz gauge gravity model with R^2-type Lagrangian is proposed. In the absence of torsion the model admits a topological phase with unfixed metric. The model possesses a minimal set of dynamical degrees of freedom for the torsion. Remarkably, the torsion has the same number of dynamical of-shell degrees of freedom as the metric tensor.

Charge confinement and vacuum structure in the 1 + 1 dimensional Higgs model
Abstract We demonstrate that the 1 + 1 dimensional Higgs model is equivalent to the massive sine-Gordon model, and hence to the massive Schwinger model in a special case. We do this by deriving a dual Lagrangian which embodies instanton effects. Based on this equivalence, we discuss charge confinement and vacuum structure in the Lagrangian formalism.

Dynamical fermions, centre vortices, and emergent phenomena [PDF]
The non-trivial ground-state vacuum fields of QCD form the foundation of matter. Here we examine the centre vortices identified within the ground-state fields of lattice QCD.

The chiral condensate of N f = 2 + 1 QCD from the spectrum of the staggered Dirac operator
We compute the chiral condensate of 2 + 1 QCD from the mode number of the staggered Dirac operator, performing controlled extrapolations to both the continuum and the chiral limit.

Different Faces of Confinement
In this review, we provide a short outlook of some of the current most popular pictures and promising approaches to non-perturbative physics and confinement in gauge theories. A qualitative and by no means exhaustive discussion presented here covers such
