Effect of the Scalar Condensate on the Linear Gauge Field Response in the Abelian Higgs Model
نویسنده
چکیده
The effective equations of motion for low-frequency mean gauge fields in the Abelian Higgs model are investigated in the presence of a scalar condensate, near the high temperature equilibrium. We determine the current induced by an inhomogeneous background gauge field in the linear response approximation up to O(e), assuming adiabatic variation of the scalar fields. The physical degrees of freedom are found and a physical gauge choice for the numerical study of the combined Higgs+gauge evolution is proposed.

Singlet scalar dark matter in noncommutative space
In this paper, we examine the singlet scalar dark matter annihilation to becoming the Standard Model particles in the non-commutative space. In the recent decades, many candidates of dark matter have been offered, but our information about the nature of dark matter is still limited. There are such particle candidates as scalar matetr, fermion, boson, gauge boson, etc.; however, they have nei...
متن کاملBreaking an Abelian gauge symmetry near a black hole horizon
I argue that coupling the Abelian Higgs model to gravity plus a negative cosmological constant leads to black holes which spontaneously break the gauge invariance via a charged scalar condensate slightly outside their horizon. This suggests that black holes can superconduct.
متن کاملNon-perturbative Dynamics in the Physical Sector
Two dimensional scalar electrodynamics is the coupling of a U(1) gauge field to a scalar complex field, where the potential can be chosen arbitrarily. Associated to the Higgs potential, the model corresponds to the well-known abelian Higgs model which has been used to illustrate spontaneous gauge symmetry breaking, or provides an effective description for superconductivity through the Landau–Gi...
متن کاملSu(2) Abelian Projected Action for Renormali- Sation Group Flows
The dual Meissner effect scenario of confinement is analysed using exact renormalisation group (ERG) equations. In particular, the low energy regime of SU(2) Yang-Mills (YM) is studied in a maximal Abelian gauge (MAG). It is shown that under general conditions the effective action derived when integrated using ERG methods contains the relevant degrees of freedom for confinement. In addition, th...
متن کاملNon-renormalizability of a SSB gauge theory induced by a non-linear fermion-Higgs coupling of canonical dimension 4
We consider an abelian gauge theory with spontaneously broken symmetry containing a scalar-fermion coupling which is non-linear in the Higgs field. Although in the unitary gauge it reduces to a pure Yukawa term, suggesting that the theory is renormalizable, the one loop divergence structure in this gauge in the fermion-fermion elastic scattering amplitude shows this is not so. Comparison is mad...
