Definability and a Nonlinear Sigma Model
The concept of definability of physical fields is introduced and a set-theoretical foundation for fields is proposed. In this foundation, we derive a nonlinear sigma model from a null postulate and then show that quantization of the model is necessary and sufficient for definability. We also obtain compactification of the spatial dimensions effectively and show its equivalence to quantization. ...
متن کاملNonlinear Sigma Model in Three Dimensions
We study the UV properties of the three-dimensional N = 4 SUSY nonlinear sigma model whose target space is T ∗(CPN−1) (the cotangent bundle of CPN−1) to higher orders in the 1/N expansion. We calculate the β-function to next-to-leading order and verify that it has no quantum corrections at leading and next-to-leading orders.
متن کاملIntegrable Extension of Nonlinear Sigma Model
We propose an integrable extension of nonlinear sigma model on the target space of Hermitian symmetric space (HSS). Starting from a discussion of soliton solutions of O(3) model and an integrally extended version of it, we construct general theory defined on arbitrary HSS by using the coadjoint orbit method. It is based on the exploitation of a covariantized canonical structure on HSS. This ter...
متن کاملKinks in a nonlinear massive sigma model.
We describe the kink solitary waves of a massive nonlinear sigma model with an S2 sphere as the target manifold. Our solutions form a moduli space of nonrelativistic solitary waves in the long wavelength limit of ferromagnetic linear spin chains.
متن کامل3 Definability and a Nonlinear Sigma Model
The concept of definability of physics fields is introduced and a set-theoretical foundation is proposed. In this foundation, we obtain a scale invariant nonlinear sigma model and then show that quantization of the model is necessary and sufficient for definability. We also obtain com-pactification of the spatial dimensions effectively and show its equivalence to quantization. We look to provid...
