Dynamics of BPS Dyons: Effective Field Theory Approach
Dongsu Bak, Choonkyu Lee, Kimyeong Lee
Based on a detailed analysis of nonlinear field equations of the SU(2) Yang-Mills-Higgs system, we obtain the effective field theory describing low-energy interaction of BPS dyons…
Boundary degrees of freedom in fractional quantum Hall effect: Excitations on common boundary of two samples
Dongsu Bak, Sang Pyo Kim, Sung Ku Kim +2
Using the Carlip's method we have derived the boundary action for the fermion Chern-Simons theory of quantum Hall effects on a planar region with a boundary. We have computed both…
Moduli Space Dynamics of a First-Order Vortex System
Dongsu Bak, Hyuk-jae Lee
The moduli space dynamics of vortices in the Jackiw-Pi model where a non-relativistic Schrodinger field couples minimally to Chern-Simons gauge field, is considered. It is shown th…
Radiation Damping of a BPS Monopole; an Implication to S-duality
Dongsu Bak, Hyunsoo Min
The radiation reaction of a BPS monopole in the presence of incident electromagnetic waves as well as massless Higgs waves is analyzed classically. The reactive forces are compared…
