Supersymmetric Q-Lumps in the Grassmannian nonlinear sigma models
Dongsu Bak, Sang-Ok Hahn, Joohan Lee +1
We construct the N=2 supersymmetric Grassmannian nonlinear sigma model for the massless case and extend it to massive N=2 model by adding an appropriate superpotential. We then stu…
Superfield formalism for the one loop effective action and CP(N) model in three dimensions
Jin-Ho Cho, Sang-Ok Hahn, Phillial Oh +2
To obtain the one loop effective action for a given superfield theory, one encounters the notion such as the `supertrace' of a differential operator on superspace. We develop, in a…
Path integral formulation of Hodge duality on the brane
Sang-Ok Hahn, Youngjai Kiem, Yoonbai Kim +1
In the warped compactification with a single Randall-Sundrum brane, a puzzling claim has been made that scalar fields can be bound to the brane but their Hodge dual higher-rank ant…
Quantum Mechanics of Integrable Spins on Coadjoint Orbits
Sang-Ok Hahn, Phillial Oh, Myung-Ho Kim
We investigate classical integrable spins defined on the reduced phase spaces of coadjoint orbits of and study quantum mechanics of them. After discussions on a complete…
