The de Broglie–Bohm Quantum Theory and Its Application to Quantum Cosmology

Abstract: We review the de Broglie–Bohm quantum theory. It is an alternative description of quantum phenomena in accordance with all the quantum experiments already performed. Essentially, it is a dynamical theory about objectively real trajectories in the configuration space of the physical system under investigation. Hence, it is not necessarily probabilistic, and it dispenses with the collapse postulate, making it suitable to be applied to cosmology. The emerging cosmological models are usually free of singularities,… Show more

“…We will focus on the de Broglie-Bohm interpretation of quantum cosmology [15] (see [12,[16][17][18][19] for review articles). Here the position of a particle considered in section II is replaced by the field value φ and the parameter α which determines the scale factor via a = e α .…”

“…Existem diversas abordagens sobre de que forma a teoria se conecta à realidade que percebemos [4]. Dentre as muitas escolas de pensamento estão a interpretação de Copenhagen [6], a interpretação de De Broglie-Bohm [7][8][9], a interpretação de muitos mundos [10] e a interpretação de histórias consistentes [11]. Importantes questões são investigadas em cada uma dessas (e outras) abordagens, incluindo o caráter determinista ou probabilístico da teoria e o chamado problema da medida [12].…”
