Some recent results on contact or point supported potentials
Luis M. Nieto, Manuel Gadella, Juan M. Mateos-Guilarte +2
We introduced some contact potentials that can be written as a linear combination of the Dirac delta and its first derivative, the - interaction. After a simple general pres…
Higgs phase in a gauge non-linear -model. Two species of BPS vortices and their zero modes
Alberto Alonso-Izquierdo, Juan Mateos-Guilarte
In this paper zero modes of fluctuation are dissected around the two species of BPS vortices existing in the critical Higgs phase, where the scalar and vector meson masses are equa…
Two-point one-dimensional - interactions: non-abelian addition law and decoupling limit
M. Gadella, J. Mateos Guilarte, J. M. Munoz-Castaneda +1
In this contribution to the study of one dimensional point potentials, we prove that if we take the limit on a potential of the type $v_0δ({y})+{2}v_1δ'({y})+w_0δ({y}-q)+…
Gilkey-de Witt heat kernel expansion and zero modes
Alberto Alonso-Izquierdo, Juan Mateos-Guilarte
In this paper we propose a generalization of the Gilkey-de Witt heat kernel expansion, designed to provide us with a precise estimation of the heat trace of non-negative Schroeding…
Kink fluctuation asymptotics and zero modes
Alberto Alonso-Izquierdo, Juan Mateos-Guilarte
In this paper we propose a refinement of the heat kernel/zeta function treatment of kink quantum fluctuations in scalar field theory, further analyzing the existence and implicatio…
On a family of (1+1)-dimensional scalar field theory models: kinks, stability, one-loop mass shifts
Alberto Alonso-Izquierdo, Juan Mateos-Guilarte
In this paper we construct a one-parametric family of (1+1)-dimensional one-component scalar field theory models supporting kinks. Inspired by the sine-Gordon and models, we…
