Integrable Models, SUSY Gauge Theories, and String Theory
Soonkeon Nam
We consider the close relation between duality in N=2 SUSY gauge theories and integrable models. Various integrable models ranging from Toda lattices, Calogero models, spinning top…
Self-Dual Chern-Simons Solitons and Generalized Heisenberg Ferromagnet Models
Phillial Oh, Q-Han Park
We consider the (2+1)-dimensional gauged Heisenberg ferromagnet model coupled with the Chern-Simons gauge fields. Self-dual Chern-Simons solitons, the static zero energy solution s…
Gravitational dressing of massive soliton theories
Ioannis Bakas, Q-Han Park
The massive soliton theories describe integrable perturbations of WZW cosets as generalized multi-component sine-Gordon models. We study their coupling to 2-dim gravity in the conf…
Scattering of Solitons in Derivative Nonlinear Schrödinger Model
Hyunsoo Min, Q-Han Park
We show that the chiral soliton model recently introduced by Aglietti et al. can be made integrable by adding an attractive potential with a fixed coefficient. The modified model i…
More on Generalized Heisenberg Ferromagnet Models
Phillial Oh, Q-Han Park
We generalize the integrable Heisenberg ferromagnet model according to each Hermitian symmetric spaces and address various new aspects of the generalized model. Using the first ord…
Integrable structure in supersymmetric gauge theories with massive hypermultiplets
Changhyun Ahn, Soonkeon Nam
We study the quantum moduli space of vacua of supersymmetric gauge theories coupled to flavors of quarks in the fundamental representation. We identify the mo…
