Index theorem for topological excitations on R^3 * S^1 and Chern-Simons theory
Erich Poppitz, Mithat Unsal
We derive an index theorem for the Dirac operator in the background of various topological excitations on an R^3 \times S^1 geometry. The index theorem provides more refined data t…
Confinement in Yang--Mills: Elements of a Big Picture
M. Shifman, M. Unsal
We present a nontechnical review of the current understanding of the phenomenon of color confinement. The emphasis is put on recent advances. This is a combined and slightly expand…
On Yang-Mills Theories with Chiral Matter at Strong Coupling
M. Shifman, Mithat Unsal
Strong coupling dynamics of Yang--Mills theories with chiral fermion content remained largely elusive despite much effort over the years. In this work, we propose a dynamical frame…
QCD-like Theories on R_3\times S_1: a Smooth Journey from Small to Large r(S_1) with Double-Trace Deformations
Mikhail Shifman, Mithat Unsal
We consider QCD-like theories with one massless fermion in various representations of the gauge group SU. The theories are formulated on . In the decompactifica…
