A study of entangled systems in the many-body signed particle formulation of quantum mechanics

A study of entangled systems in the many-body signed particle formulation of quantum mechanics
Jean Michel Sellier, Kristina G. Kapanova
Recently a new formulation of quantum mechanics has been introduced, based on signed classical field-less particles interacting with an external field by means of only creation and annihilation events. In this article, we extend this novel theory to the case of many-body problems. We show that, when restricted to spatial finite domains and discrete momentum space, the proposed extended theory is equivalent to the time-dependent many-body Wigner Monte Carlo method. In this new picture, the treatment of entangled systems comes naturally and, therefore, we apply it to the study of quantum entangled systems. The latter is represented in terms of two Gaussian wave packets moving in opposite directions. We introduce the presence of a dissipative background and show how the entanglement is affected by different (controlled) configurations. Recently a new formulation of quantum mechanics has been introduced, based on signed classical field-less particles interacting with an external field by means of only creation and annihilation events. In this article, the theory is extended to the case of many-body problems. The novel theory provides the ability of dealing with entangled systems in the presence of environmental noise in a time-dependent fashion. A study is presented of entangled quantum systems (a two-body systems) immersed in a controlled perturbative background, investigating the effects of various (toy) backgrounds on entangled systems.
