Higher Spin Extension of Ginzburg-Landau model for superconductivity

Friday 13 Feb 2026, 13:00 → 14:00 Europe/Athens

We extend the phenomenological Ginzburg-Landau model for superconductivity to include particles of higher spin. Higher spin particles can be simulated microscopically as larger groups of electrons (e.g. quadruplets) than the standard Cooper pairs predicted by BCS theory. To account for these composites, higher rank vector and tensor non-gauge fields can be included in the Lagrangian, which act as sources of higher rank tensor gauge fields. In  this project we extend the particles up to one rank higher (including auxiliary fields) and  examine possible modifications of the fundamental phenomenological quantities that govern the effect of superconductivity (penetration depth, correlation length, energy gap).
