Higgs Mechanism at Finite Chemical Potential with Type-IINambu-Goldstone Boson
SummaryWe analyzed Higgs Mechanism at finite chemical potential with type-II NG boson with Rx gauge
Result: ・Total physical degrees of freedom correctly conserved -- Not only the massless NG bosons (type I & II) but also the massive mode induced by the chemical potential became unphysical ・Models: gauged SU(2) model, Glashow-Weinberg-Salam type gauged U(2) model, gauged SU(3) model Future Directions: ・Higgs Mechanism with type-II NG bosons in nonrelativistic systems (ultracold atoms in optical lattice)?
-- What is the relation between the Algebraic method (Nambu 2002) and the Nielsen Chadha theorem?
・Algebraic method: counting NG bosons without deriving dispersions ・Nielsen-Chadha theorem: counting NG bosons from dispersions
