Álgebra de Heisenberg deformada via modificação no operador de translação

Abstract

We present an algebra of deformed Heisenberg-type [^ x; p ^] = i~f(^ x) arising from a rede nition of the translation operator. We point out that the Hilbert space should be used for the representation of the algebra in question and show the explicit form of the position and momentum operators in this space, in addition, we also write the equations that governs the time evolution of quantum systems (the Schrödinger equation) and use it to solve a traditional problem in the usual quantum mechanics: the harmonic oscillator immersed in a uniform electric eld . It should also point out that we used an unusual method to the solution of the harmonic oscillator, the method of the Laplace transform.
