On Topological Terms in the O(3) Nonlinear Sigma Model
Topological terms in the O(3) nonlinear sigma model in (1 + 1) and (2 + 1) dimensions are re-examined based on the description of the SU(2)-valued field g. We first show that the topological soliton term in (1+1) dimensions arises from the unitary representations of the group characterizing the global structure of the symmetry inherent in the description, in a manner analogous to the appearance...
متن کاملA Comment on the Renormalization of the Nonlinear Sigma Model
We consider the recently proposed renormalization procedure for the nonlinear sigma model, consisting in the recursive subtraction of the divergences in a symmetric fashion. We compare this subtraction with the conventional procedure in power counting renormalizable (PCR) theories. We argue that symmetric subtraction in the nonlinear sigma model does not follow the lore by which nonrenormalizab...
متن کاملDefinability 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...
