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 gaples…

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 backgro…

Inhomogeneous Abelian Chern-Simons Higgs Model with New Inhomogeneous BPS Vacuum and Solitons

Yoonbai Kim, O-Kab Kwon, Hanwool Song +1

We study an inhomogeneous U(1) Chern-Simons Higgs model with a magnetic impurity in the BPS limit. The potential is sextic with both broken and unbroken phases, but its minimum var…

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…

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…
