Journal Article

By analogy with the Landau-Ginzburg theory of ordinary zero-form symmetries, we introduce and develop a Landau-Ginzburg theory of one-form global symmetries, which we call mean string field theory. The basic dynamical variable is a string field – def... Read More about Mean string field theory: Landau-Ginzburg theory for 1-form symmetries.

Numerical simulation of self-dual U(1) lattice field theory with electric and magnetic matter (2022)
Presentation / Conference Contribution
Anosova, M., Gattringer, C., Iqbal, N., & Sulejmanpasic, T. (2022, December). Numerical simulation of self-dual U(1) lattice field theory with electric and magnetic matter. Presented at Proceedings of The 38th International Symposium on Lattice Field Theory — PoS(LATTICE2021)

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.

Towards traversable wormholes from force-free plasmas (2022)
Journal Article
Iqbal, N., & Ross, S. F. (2022). Towards traversable wormholes from force-free plasmas. SciPost Physics, 12(3), Article 086. https://doi.org/10.21468/scipostphys.12.3.086

The near-horizon region of magnetically charged black holes can have very strong magnetic fields. A useful low-energy effective theory for fluctuations of the fields, coupled to electrically charged particles, is force-free electrodynamics. The low e...

Effective description of non-equilibrium currents in cold magnetized plasma (2022)
Journal Article
Iqbal, N. (2022). Effective description of non-equilibrium currents in cold magnetized plasma. SciPost Physics, 12(2), Article 078. https://doi.org/10.21468/scipostphys.12.2.078

The dynamics of cold strongly magnetized plasma -- traditionally the domain of force-free electrodynamics -- has recently been reformulated in terms of symmetries and effective field theory, where the degrees of freedom are the momentum and magnetic...
