Confinement of an electron in a non homogeneous magnetic field: Integrable vs superintegrable quantum systems

In the “big picture” perspective of the recent years that we have described in Brazil, Spain, Portugal and Puerto Rico there are some similarities and important differences,

In this paper we have re-considered the case of spin-flavour precession solu- tions, based on non-zero transition magnetic moments of Majorana neutrinos taking into account the

The idea to do that is to extend the Darboux transformations for second order linear differential equations in matrix form to Darboux transformations for their second symmetric

The quantum chemical methods employed make use of explicit wave functions expanded in terms of flexible basis sets, multiconfigurational self-consistent-field and

The expression ((having become common since the spring)) -the French original reads ((etant devenues populaires des le printems»- refers to the spring of 1708 and is

Fris et al [6] studied the superintegrability in the Euclidean plane and proved the existence of four families of superintegrable systems with quadratic in the momenta constants

In addition to the mentioned limits, the case where each of the mean field wave functions are expressed in different single-particle basis is considered.. The two bases are related

As their favorite observables the authors pick the 2-point function of a scalar field, but only solve the problem in two different quasi-static limits of an in-falling dust shell:
