Nas últimas décadas constata-se um crescente número de artigos em diversas áreas da Física dedicados a desenvolver e aplicar o formalismo de Weyl-Wigner nos mais diferentes sistemas físicos. A possibilidade de aprofundarmos os nossos conhecimen

Resumo Ao fundamentar as bases da Mecânica Quântica através da solução de um problema matemático associado a possíveis inconsistĉncias na relação de comutação para os operadores posição e momento linear, von Neumann lança as bases teó

We consider the problems of maximizing the entanglement negativity of X-form qubit-qutrit density matrices with (i) a fixed spectrum and (ii) a fixed purity. In the first case, the problem is solved in full generality whereas, in the latter, partial

We propose a self-consistent theoretical framework for a wide class of physical systems characterized by a finite space of states which allows us, within several mathematical virtues, to construct a discrete version of the Weyl–Wigner–Moyal (WWM)

For every possible spectrum of $2^N$-dimensional density operators, we construct an $N$-qubit X-state of same spectrum and maximal genuine multipartite (GM-) concurrence, hence characterizing a global unitary transformation that --- constrained to ou

Adopting the framework of the Jaynes–Cummings model with an external quantum field, we obtain exact analytical expressions of the normally ordered moments for any kind of cavity and driving fields. Such analytical results are expressed in the integ

An approach featuring s-parametrized quasiprobability distribution functions is developed for situations where a circular topology is observed. For such an approach, a suitable set of angle–angular momentum coherent states must be constructed in an

Adopting the framework of the generalized q-deformed Heisenberg?Weyl algebra , we present a mathematical procedure which leads us to obtain analytical expressions for a general class of q-deformed coherent states associated with the different pattern
