(Meta)stable closed vortices in 3+1 dimensional gauge theories with an extended Higgs sector
Antti J. Niemi, Kaupo Palo, Sami Virtanen
In gauge theories with an extended Higgs sector the classical equations of motion can have solutions that describe stable, closed finite energy vortices. Such vortices separate two…
On the Characterization of Classical Dynamical Systems Using Supersymmetric Nonlinear -models
A. J. Niemi, K. Palo
We construct a two dimensional nonlinear -model that describes the Hamiltonian flow in the loop space of a classical dynamical system. This model is obtained by equivariantizing…
Equivariant Morse theory and quantum integrability
A. J. Niemi, K. Palo
We investigate an equivariant generalization of Morse theory for a general class of integrable models. In particular, we derive equivariant versions of the classical Poincaré-Hopf…
Symplectic Geometry of Supersymmetry and Nonlinear Sigma Model
Kaupo Palo
Recently it has been argued, that Poincaré supersymmetric field theories admit an underlying loop space hamiltonian (symplectic) structure. Here shall establish this at the level o…
On Quantum Integrability and the Lefschetz Number
A. J. Niemi, K. Palo
Certain phase space path integrals can be evaluated exactly using equivariant cohomology and localization in the canonical loop space. Here we extend this to a general class of mod…
