Comments on QCD3 and anomalies with fundamental and adjoint matter (2022)
Journal Article
Lohitsiri, N., & Sulejmanpasic, T. (2022). Comments on QCD3 and anomalies with fundamental and adjoint matter. Journal of High Energy Physics, 2022(10), Article 81. https://doi.org/10.1007/jhep10%282022%29081

’t Hooft anomaly matching is powerful for constraining the low energy phases of gauge theories. In 3d one common anomaly is the parity anomaly in a T-symmetric theory where one cannot gauge the global symmetry group without breaking the time-reversal...

Numerical simulation of self-dual U(1) lattice field theory with electric and magnetic matter (2022)
Conference Proceeding
Anosova, M., Gattringer, C., Iqbal, N., & Sulejmanpasic, T. (2022). Numerical simulation of self-dual U(1) lattice field theory with electric and magnetic matter. . https://doi.org/10.22323/1.396.0386

We study a recently proposed formulation of U(1) lattice field theory with electric and magnetic matter based on the Villain formulation. This discretization allows for a duality that gives rise to relations between weak and strong gauge coupling. Th...

Phase structure of self-dual lattice gauge theories in 4d (2022)
Journal Article
Anosova, M., Gattringer, C., Iqbal, N., & Sulejmanpasic, T. (2022). Phase structure of self-dual lattice gauge theories in 4d. Journal of High Energy Physics, 2022(6), Article 149. https://doi.org/10.1007/jhep06%282022%29149

We discuss U(1) lattice gauge theory models based on a modified Villain formulation of the gauge action, which allows coupling to bosonic electric and magnetic matter. The formulation enjoys a duality which maps electric and magnetic sectors into eac... Read More about Phase structure of self-dual lattice gauge theories in 4d.

Self-dual U(1) lattice field theory with a θ-term (2022)
Journal Article
Anosova, M., Gattringer, C., & Sulejmanpasic, T. (2022). Self-dual U(1) lattice field theory with a θ-term. Journal of High Energy Physics, 2022(4), Article 120. https://doi.org/10.1007/jhep04%282022%29120

We study U(1) gauge theories with a modified Villain action. Such theories can naturally be coupled to electric and magnetic matter, and display exact electric-magnetic duality. In their simplest formulation without a θ-term, such theories are ultra-... Read More about Self-dual U(1) lattice field theory with a θ-term.

Ising model as a U(1) lattice gauge theory with a θ -term (2021)
Journal Article

We discuss a gauged XY model a θ -term on an arbitrary lattice in 1 + 1 dimensions and show that the theory reduces exactly to the 2d Ising model on the dual lattice in the limit of the strong gauge coupling, provided that the topological term is def...

First-Principles Simulations of 1+1D Quantum Field Theories at θ=π and Spin Chains (2020)
Journal Article

We present a lattice study of a 2-flavor U(1) gauge-Higgs model quantum field theory with a topological term at θ = π. Such studies are prohibitively costly in the standard lattice formulation due to the sign problem. Using a novel discretization of...

Topological terms in abelian lattice field theories (2020)
Conference Proceeding

In this contribution we revisit the lattice discretization of the topological charge for abelian lattice field theories. The construction departs from an initially non-compact discretization of the gauge fields and after absorbing 2π shifts of the ga...

Quantum systems with multiple degenerate classical harmonic minima exhibit new non-perturbative phenomena which are not present for the double-well and periodic potentials. The simplest characteristic example of this family is the triple-well potenti... Read More about Bions and Instantons in Triple-well and Multi-well Potentials.

Universality between vector-like and chiral quiver gauge theories: anomalies and domain walls (2020)

We study low-energy dynamics of [SU(N)]K chiral quiver gauge theories in connection with N = 1 super Yang-Mills (SYM) theory, and quantum chromodynamics with bi-fundamental fermions (QCD(BF)). These theories can be obtained by ZK orbifold projections... Read More about Universality between vector-like and chiral quiver gauge theories: anomalies and domain walls.
