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…
Existence and Uniqueness of BPS Vacuum and Multi-vortices in Inhomogeneous Abelian Higgs Model
SeungJun Jeon, Chanju Kim, Yoonbai Kim
The BPS limit of the inhomogeneous abelian Higgs model is considered in -dimensions. The second order Bogomolny equation is examined in the presence of an inhomogeneity expr…
Vacuum and Vortices in Inhomogeneous Abelian Higgs Model
Yoonbai Kim, SeungJun Jeon, O-Kab Kwon +2
The inhomogeneous abelian Higgs model with a magnetic impurity in the BPS limit is studied for both relativistic and nonrelativistic regimes. Though the symmetry of spatial transla…
