Generalized Yang-Mills theory: Interpolating between SDYM and YM
Tolga Domurcukgül, Hao Geng, Mendel Nguyen +1
We construct a generalized Yang-Mills (YM) theory with two real couplings, interpolating continuously between the Self-Dual Yang-Mills (SDYM) limit (also called Chalmers-Siegel the…
Self-dual monopole loops, instantons and confinement
Mendel Nguyen, Mithat Ünsal
It is well-known that the standard instanton analysis in 4d Yang-Mills is plagued with the instanton size moduli problem, which renders the instanton contribution to vacuum energy…
Fractionalization of flux tubes in 3d and screening by emergent electric charges in 2d
Mendel Nguyen, Mithat Ünsal
We consider a class of 3d theories with a magnetic symmetry in which confinement is generated by charge clusters of monopoles. Such theories naturally arise in qu…
Phases of theories with 1-form symmetry and the roles of center vortices and magnetic monopoles
Mendel Nguyen, Tin Sulejmanpasic, Mithat Ünsal
We analyze the phases of theories which only have a microscopic 1-form symmetry, starting with a topological BF theory and deforming it in accordance with microscopi…
Refined instanton analysis of the 2D model: mass gap, theta dependence, and mirror symmetry
Mendel Nguyen, Mithat Ünsal
We address nonperturbative dynamics of the two-dimensional bosonic and supersymmetric models for general by developing new tools directly on .…
Study of gapped phases of 4d gauge theories using temporal gauging of the 1-form symmetry
Mendel Nguyen, Yuya Tanizaki, Mithat Ünsal
To study gapped phases of d gauge theories, we introduce the temporal gauging of -form symmetry in d quantum field theories (QFTs), thereby defining effecti…
Winding theta and destructive interference of instantons
Mendel Nguyen, Yuya Tanizaki, Mithat Ünsal
While the dependence of field theories is periodic, the ground-state wavefunctions at and often belong to different classes of symmetry-protected topological st…
Non-invertible 1-form symmetry and Casimir scaling in 2d Yang-Mills theory
Mendel Nguyen, Yuya Tanizaki, Mithat Ünsal
Pure Yang-Mills theory in 2 spacetime dimensions shows exact Casimir scaling. Thus there are infinitely many string tensions, and this has been understood as a result of non-propag…
Semi-Abelian gauge theories, non-invertible symmetries, and string tensions beyond -ality
Mendel Nguyen, Yuya Tanizaki, Mithat Ünsal
We study a 3d lattice gauge theory with gauge group , which is obtained by gauging the global symmetry of a pure $\mathrm{U}…
