Title: Confinement and Deconfinement in Gauge Theories : A Quantum Field Theory Abstract: After a brief discussion of small and large gauge transformations and the nature of observables, we discuss superselection sectors in gauge theories. There are an… Read More

Speaker: Swapnamay MondalTitle: Black hole microstates in String TheoryAbstract: Quantum mechanically a black hole emits thermalradiation and has an entropy equalling a quarter of its surface areain Planck units. This implies the existence of black hole microstates,something inconceivable… Read More

Title: Poisson gauge theory Abstract: Motivated by noncommutative gauge theory, I will discuss a novel approach to gauge theory with underlying non-trivial Poisson structure over space-time. The goal is to formulate a gauge theory which reproduces the standard… Read More

Title: Muon g−2 and a type-X two-Higgs-doublet scenario: Some studies in high-scale validity Abstract: We study the high-scale validity of a type-X two Higgs doublet scenario, which provides an explanation of the observed value of muon (g−2). This… Read More

Title: The 3D Plaquette Ising Model, subsystem symmetries and fractons Abstract: A fracton is an emergent topological quasiparticle excitation which has restricted mobility. Interest in models possessing such excitations was piqued by work by Pretko and Vijay, Haah… Read More

The Dublin Institute for Advanced Studies (DIAS) is a government-funded academic research institution. The Geophysics section in DIAS operates the Irish National Seismic Network (INSN), since 2017 with support from the Geological Survey Ireland (GSI). The Seismic Network… Read More

Title: Aspects of higher dimensional quantum Hall effect: Effective actions, entanglement entropy Abstract: I will present the formulation of higher dimensional QHE on complex projective spaces, with both abelian (electromagnetic) and nonabelian background fields and derive the effective… Read More
