Generalized Zeta Functions and One-loop Corrections to Quantum Kink Masses
نویسندگان
چکیده
A method for describing the quantum kink states in the semi-classical limit of several (1+1)-dimensional field theoretical models is developed. We use the generalized zeta function regularization method to compute the one-loop quantum correction to the masses of the kink in the sine-Gordon and cubic sinh-Gordon models and another two P(φ)2 systems with polynomial self-interactions.

One-loop corrections to classical masses of kink families
One-loop corrections to kink masses in a family of (1+1)-dimensional field theoretical models with two real scalar fields are computed. A generalized DHN formula applicable to potentials with and without reflection is obtained. It is shown how half-bound states arising in the spectrum of the second order fluctuation operator for one-component topological kinks and the vacuum play a central rôle...
متن کاملInitial problem for heat equation with multisoliton inhomogeneity and one-loop quantum corrections
The generalized zeta-function is built by a dressing method based on the Darboux covariance of the heat equation and used to evaluate the correspondent functional integral in quasiclassical approximation. Quantum corrections to a kink-like solutions of LandauGinzburg model are calculated.

One-loop corrections to kink masses in a family of (1+1)-dimensional field theoretical models with two scalar fields are computed. A generalized DHN formula applicable to reflection and reflectionless potentials is obtained. It is thus shown how half-bound states arising in the spectrum of the second order fluctuation operator around TK1 kinks and the vacuum play a central rôle in the computati...
متن کاملQuantum corrections to the mass of self-dual vortices
The mass shift induced by one-loop quantum fluctuations on self-dual ANO vortices is computed using heat kernel/generalized zeta function regularization methods. 1. In this Letter we shall compute the one-loop mass shift for Abrikosov-NielsenOlesen self-dual vortices in the Abelian Higgs model. Non-vanishing quantum corrections to the mass of N = 2 supersymmetric vortices were reported during t...
متن کاملQuantum corrections to static solutions of Nahm equation and Sin-Gordon models via generalized zeta-function
One-dimensional Yang-Mills Equations are considered from a point of view of a class of nonlinear Klein-Gordon-Fock models. The case of self-dual Nahm equations and nonself-dual models are discussed. A quasiclassical quantization of the models is performed by means of generalized zeta-function and its representation in terms of a Green function diagonal for a heat equation with the correspondent...
