I'm not sure, whether I understand your question right, but if it is about superconductivity, you are (nearly) on the right track, because from an effective-field theory point of view in a superconducting material the electromagnetic gauge symmetry is "Higgsed", i.e., the photon get massive via the Anderson-Higgs mechanism, which is mostly known in the ⦠In high-energy physics, the Higgs field couples to gauge bosons and fermions and gives mass to their elementary excitations.

The U.S. Department of Energy's Office of Scientific and Technical Information Spontaneous Symmetry Breaking In The Higgs Mechanism. Materials only âturn onâ their superconductivity below -140 degrees Celsius. To be more precise: Superconductivity is effectively described by the Higgs mechanism of QED in the medium. The concept of mass generation by means of the Higgs mechanism was strongly inspired by earlier works on the MeissnerâOchsenfeld eËect in superconductors. In fact, this analogy is an abelian example for the Higgs mechanism, through which in high-energy physics the masses of the electroweak gauge particles, W ± and Z are generated. A physical example in which the Higgs mechanism actually takes place is superconductivity. The AndersonâHiggs mechanism is now a cornerstone of both particle and condensed-matter physics. The Higgs mechanism is a type of superconductivity which occurs in the vacuum. This effect is a consequence of the composite nature of the Higgs field of superconductivity and the broken Lorentz invariance in a solid.

Higgs mechanism in Superconductivity. The Higgs mechanism is an essential but elusive component of the Standard Model of particle physics. BCS theory or BardeenâCooperâSchrieffer theory (named after John Bardeen, Leon Cooper, and John Robert Schrieffer) is the first microscopic theory of superconductivity since Heike Kamerlingh Onnes's 1911 discovery. The Higgs boson, which was discovered in 2012, is therefore also referred to as the âGod particleâ. The length is identical with "London's penetration depth" in the theory of superconductivity.

The most well known connection is with the Brout-Englert-Higgs (BEH) mechanism that gives mass to the W and Z force carrier particles. The Higgs mechanism is normally associated with high energy physics, but its roots lie in superconductivity. The Higgs boson, which was discovered in 2012, is therefore also referred to as the âGod particleâ. The Higgs mechanism is an essential but elusive component of the Standard Model of particle physics. On Oct. 8, the 2013 Nobel Prize in Physics was awarded to Peter Higgs and François Englert, two physicists who, in separate 1964 papers, proposed the basis of the particleâs existence, the Higgs mechanism. The Higgs boson is a wave in that field. May ⦠The Higgs field was proposed in 1964 as a new kind of field that fills the entire Universe and gives mass to all elementary particles. The Higgs model we discuss has two superconducting components and an axion-like magnetoelectric term with the phase difference of the superconducting order parameters playing the role of the axion field. The Higgs boson is a mysterious particle, different in several ways from all particles seen so far, and connected to many unanswered questions in physics. The roots of the BEH mechanism lie in the phenomenon of spontaneous symmetry breaking, which is inherent in superconductivity and superfluidity. The Higgs boson, as proposed within the Standard Model, is the simplest manifestation of the Brout-Englert-Higgs mechanism.
