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…
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…
Janus Deformation of de Sitter Space and Transitions in Gravitational Algebras
Dongsu Bak, Chanju Kim, Sang-Heon Yi
We consider a time-dependent deformation of pure de Sitter (dS) space in dS gravity coupled to a massless scalar field. It is the dS counterpart of the AdS Janus…
