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…
Isospin particle on with arbitrary number of supersymmetries
Soon-Tae Hong, Joohan Lee, Tae Hoon Lee +1
We study the supersymmetric quantum mechanics of an isospin particle in the background of spherically symmetric Yang-Mills gauge field. We show that on the number of supers…
A complete solution of a Constrained System: SUSY Monopole Quantum Mechanics
Soon-Tae Hong, Joohan Lee, Tae Hoon Lee +1
We solve the quantum mechanical problem of a charged particle on S^2 in the background of a magnetic monopole for both bosonic and supersymmetric cases by constructing Hilbert spac…
Supersymmetric Monopole Quantum Mechanics on Sphere
Soon-Tae Hong, Joohan Lee, Tae Hoon Lee +1
We study N=2 supersymmetric quantum mechanics of a charged particle on sphere in the background of Dirac magnetic monopole. We adopt CP(1) model approach in which the monopole inte…
Gauge symmetry enhancement in Hamiltonian formalism
Soon-Tae Hong, Joohan Lee, Tae Hoon Lee +1
We study the Hamiltonian structure of the gauge symmetry enhancement in the enlarged CP(N) model coupled with U(2) Chern-Simons term, which contains a free parameter governing expl…
Dirac Operators on Coset Spaces
A. P. Balachandran, Giorgio Immirzi, Joohan Lee +1
The Dirac operator for a manifold Q, and its chirality operator when Q is even dimensional, have a central role in noncommutative geometry. We systematically develop the theory of…
