Black holes immersed in modified Chaplygin-like dark fluid and cloud of strings: geodesics, shadows, and images
Xiang-Qian Li, Yoonbai Kim, Bum-Hoon Lee +2
This study investigates a black hole surrounded by a cloud of strings and a cosmological dark fluid characterized by a modified Chaplygin-like equation of state (MCDF), $p=AÏ-B/Ï…
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…
