A translation operator acting in a space with a diagonal metric is introduced to describe the motion of a particle in a quantum system. We show that the momentum operator and, as a consequence, the uncertainty relation now depend on the metric. It is

A new mechanism, valid for any smooth version of the Randall–Sundrum model, of getting localized massless vector field on the brane is described here. This is obtained by dimensional reduction of a five dimension massive two form, or Kalb–Ramond

The phase diagram of correlated disordered electron systems is calculated within dynamical mean-field theory for the Anderson-Falicov-Kimball model with nearest-neighbor and next-nearest-neighbor hoppings. The half-filled band is analyzed in terms of

The contribution of the electron-plasmon coupling to the photoluminescence spectrum of direct gap semicondutors is calculated. The photoexcited semicondutor is described as a coupled sistem of carriers and plasmons20. This coupled sistem of plasmons

No Modelo do Grupo Votante Diluído proposto, simulamos um material magnético numa uma rede regular quadrada de N variáveis de spin com dois estados σi = ±1 e rede de lado L = √ N. O estado de cada sítio pode ser modificado devido a influênci

In the present work, we study the formalism of the position-dependent translation operator (PDTO), a formalism obtained by trying to understand the consequences of space metrics in quantum mechanics (MQ). In view of this, two types of metrics were us

This work discusses the position-dependent translation operator in the Schrödinger and Heisenberg formulation of quantum mechanics. In both representations, we discuss the importance of sufficient conditions for the moment operator to be hermitian i
