Winding theta and destructive interference of instantons

Mendel Nguyen, Yuya Tanizaki, Mithat Ünsal

While the $θ$ dependence of field theories is $2 π$ periodic, the ground-state wavefunctions at $θ$ and $θ + 2 π$ often belong to different classes of symmetry-protected topological st…

Semiclassics with 't Hooft flux background for QCD with $2$ -index quarks

Yuya Tanizaki, Mithat Ünsal

We study quantum chromodynamics including the two-index symmetric or anti-symmetric quark (QCD(Sym/ASym)) on small $R^{2} \times T^{2}$ with a suitable magnetic flux. We first…

Four-fermion deformations of the massless Schwinger model and confinement

Aleksey Cherman, Theodore Jacobson, Mikhail Shifman +2

We consider the massless charge- $N$ Schwinger model and its deformation with two four-fermion operators. Without the deformations, this model exhibits chiral symmetry breaking with…
