Charged Vortex in Superconductor
Yoonbai Kim, SeungJun Jeon, Hanwool Song
We find the charged spinless vortices in the effective field theory of a Schrödinger type complex scalar field of Cooper pair, a U(1) gauge field of electromagnetism, and a gapless…
Effective Field Theory of Superconductivity
Yoonbai Kim, SeungJun Jeon, Hanwool Song
A field theory of a Schrödinger type complex scalar field of Cooper pair, a U(1) gauge field of electromagnetism, and a neutral scalar field of gapless acoustic phonon is proposed…
Field Theory of Superconductor and Charged Vortex
Yoonbai Kim, SeungJun Jeon, Hanwool Song
A Lagrangian of a Schrödinger type complex scalar field of Cooper pair, a U(1) gauge field of electromagnetism, and a neutral scalar field of acoustic phonon with constant backgrou…
Effect of Impurity on Inhomogeneous Vacuum and Interacting Vortices
SeungJun Jeon, Yoonbai Kim, Hanwool Song
We study the inhomogeneous abelian Higgs model with a magnetic impurity. The vacuum configuration of the symmetry-broken phase is not simply the constant Higgs vacuum but is a nont…
