Dispersion relations and bending losses of cylindrical and spherical shells, slabs, and slot waveguides
Gregory Kozyreff, Nirmalendu Acharyya
We derive formulas for Whispering Gallery Mode resonances and bending losses in infinite cylindrical dielectric shells and sets of concentric cylindrical shells. The formulas also…
Glueball Spectra from a Matrix Model of Pure Yang-Mills Theory
Nirmalendu Acharyya, A. P. Balachandran, Mahul Pandey +2
We present variational estimates for the low-lying energies of a simple matrix model that approximates Yang-Mills theory on a three-sphere of radius . By fixing the grou…
BRST Symmetry: Boundary Conditions and Edge States in QED
Nirmalendu Acharyya, A. P. Balachandran, Verónica Errasti Díez +2
In manifolds with spatial boundary, BRST formalism can be used to quantize gauge theories. We show that, in a gauge theory, only a subset of all the boundary conditions allo…
