A formulação dos 'estados relativos' da teoria quântica

Abstract: Publicado em xx/xx/xx O objetivo desse artigoé uma apresentação didática, em português, da interpretação dos estados relativos, publicada por Hugh Everett em 1957. Nessa apresentação, reescrevemos os argumentos originais utilizando o formalismo de Dirac de modo a simplificar sua compreensão. A apresentação foi feita sem o uso de cargas ontológicas posteriores, seguindo principalmente os textos originais de Everett. Ao longo dos tópicos, evidenciaremos quais os principais problemas enfrentados por essa interpre… Show more

“…The characterization Bohr and his collaborators gave of Everett's work was that he was unable to understand the bases of quantum theory and, therefore, was trying to solve problems that simply did not exist. In a previous work (Freitas and Freire, 2008b), we characterized the two approaches as incommensurable and, as such, only a subversion strategy could lead to a revolution in the field so that the new ideas could replace the old ones and thus obtain a monopoly on scientific authority. 16 What was considered as a problem according to one interpretation was not to the other and vice versa.…”

“…It is curious to note that years later Pinch criticized Bohm for defending, according to Pinch, an excess of creativity in science(Freire, 2019, 188) 7 The historical outline developed here is based onFreitas (2007),Freitas and Freire (2008a;2008b), and Osnaghi,Freitas and Freire (2009), that was reprinted inFreire (2015, chap. 3).…”

“…Everett's work is centered on the concept of the relative state [10,11] and, although it never gathered as many followers as 'orthodox' interpretations, it is taken seriously by many [43,44]. One of its developments was the many-worlds interpretation (MWI) [12], as Bryce DeWitt named it to stimulate debate, which was soon to raise objection, some of a more aesthetic order: it was inelegant, absurd and unnecessary to fill the universe endless invisible worlds [9,[45][46][47][48][49].…”

“…The idea that objects such as particles could be described as non-localized waves was already challenging enough, but relinquishing determinism at least in theory proved to be too much for many classical physicists. Among the several paths to understanding the emergence of the classical world, Everett's relative-state interpretation [7][8][9][10][11][12] originated the decoherence theory [4,[13][14][15][16][17][18][19][20][21][22][23]-the idea that it is the influence of the environment on the principal system and the measurement apparatus that causes the emergence of the classical world.…”
