Physical self-adjoint extensions and their spectra of the simplest one-dimensional Hamiltonian operator in which the mass is constant except for a finite jump at one point of the real axis are correctly found. Some self-adjoint extensions are used to model different kinds of semiconductor heterojunctions within the effective-mass approximation. Their properties and relation to different boundary conditions on envelope wave functions are studied. The limiting case of equal masses (with no mass…

Self-adjoint Dirac type Hamiltonians in one space dimension with a mass jump
Physical self-adjoint extensions and their spectra of the one-dimensional Dirac type Hamiltonian operator, in which both the mass and velocity are constant except for a finite jump at one point of
Energy spectra of position-dependent masses in double heterostructures
We consider position-dependent effective mass particles in double heterostructures, subject to the action of several potentials. A comparative study of the energy spectra of these particles is
Point-particle effective field theory I: classical renormalization and the inverse-square potential
A bstractSingular potentials (the inverse-square potential, for example) arise in many situations and their quantum treatment leads to well-known ambiguities in choosing boundary conditions for the


A Study of Resonances in a One-Dimensional Model with Singular Hamiltonian and Mass Jumps
We study the resonances produced in a one dimensional quantum system with an infinite potential on the negative real line plus two Dirac delta barriers centered at the points a,b>0. The system mass
Self-adjoint extensions of operators and the teaching of quantum mechanics
For the example of the infinite well potential, we point out some paradoxes which are solved by a careful analysis of what is a truly self-adjoint operator. We then describe the self-adjoint
A delta well with a mass jump
In this paper, it is shown that a one-dimensional Hamiltonian with an attractive delta potential at the origin plus a mass jump at the same point cannot have a bound state, as is the case with the
Elementary quantum models with position-dependent mass
The practical availability of semiconductor heterostructure gives a new interest to elementary quantum models for particles in piecewise flat potentials, with the new feature of a position-dependent

Instantaneous Galilean invariance is used to derive from first principles the expression for the Hamiltonian of an electron with a position-dependent effective mass, as well as the adequate boundary
The Bargmann-Wigner method in Galilean relativity
The equations of motion of a spin one particle as derived from Levy-Leblond's Galilean formulation of the Bargmann-Wigner equations are examined. Although such an approach is possible for the case of
Scattering theory of waves and particles
Much progress has been made in scattering theory since the publication of the first edition of this book fifteen years ago, and it is time to update it. Needless to say, it was impossible to
