Constraint structure of O(3) nonlinear sigma model revisited
Soon-Tae Hong, Yong-Wan Kim, Young-Jai Park +1
We study the constraint structure of the O(3) nonlinear sigma model in the framework of the Lagrangian, symplectic, Hamilton-Jacobi as well as the Batalin-Fradkin-Tyutin embedding…
Noncommutative Geometry, Extended W(infty) Algebra and Grassmannian Solitons in Multicomponent Quantum Hall Systems
Z. F. Ezawa, G. Tsitsishvili, K. Hasebe
Noncommutative geometry governs the physics of quantum Hall (QH) effects. We introduce the Weyl ordering of the second quantized density operator to explore the dynamics of electro…
Exact self-gravitating N-body motion in the CGHS model
Won Tae Kim, Edwin J. Son
In the asymptotically flat two-dimensional dilaton gravity, we present an N-body particle action which has a dilaton coupled mass term for the exact solubility. This gives nonpertu…
Nonmonotonic behavior of resistance in a superconductor-Luttinger liquid junction
H. -W. Lee, Hyun C. Lee, Hangmo Yi +1
Transport through a superconductor-Luttinger liquid junction is considered. When the interaction in the Luttinger liquid is repulsive, the resistance of the junction with a suffici…
Zero Modes and the Atiyah-Singer Index in Noncommutative Instantons
Keun-Young Kim, Bum-Hoon Lee, Hyun Seok Yang
We study the bosonic and fermionic zero modes in noncommutative instanton backgrounds based on the ADHM construction. In k instanton background in U(N) gauge theory, we show how to…
Propagators in Noncommutative Instantons
Bum-Hoon Lee, Hyun Seok Yang
We explicitly construct Green functions for a field in an arbitrary representation of gauge group propagating in noncommutative instanton backgrounds based on the ADHM construction…
