Abstract

In 1981 Caianiello showed that maximal acceleration arises when quantum considerations namely the positionmomentum uncertainty relations are incorporated into the geometry of a particle in eightdimensional phase space The timeenergy uncertainty relation was later used by Caianiello in an alternative derivation of maximal acceleration The alternative derivation given in 1984 was subsequently criticized by Sharma and Srirankanathan This criticism is shown here to be unfounded Caianiello’s 1984 derivation is also analyzed It is found that while maximal acceleration follows from an equation due to Landau and Lifshitz this equation cannot be treated as a consequence of the timeenergy uncertainty relationВ 1981 г Каянелло показвл что возникает максимальное ускорение когда квантовое рассмотрение а именно соотношения неопределенностей между координатами и импульсами включается в геометрию частицы в восьмимерном фазовом пространстве Соотношение неопределенностей между временем и энергией использовалось позднее Каянелло в альтернативном выводе максимального ускорения Этот альтернативный вывод проведенный в 1984 г был подвергнут критике в работе Шарма и Шриранканатана В этой работе показывается что эта критика необоснована Также анализируется вывод Каянелло проведенный в 1984 г Получено что хотя максимальное ускорение следует из уравнения Ландау и Лифшица это уравнение не может может рассматриваться как следствие соотношения неопределенностей между временем и энергиейNel 1981 Caianiello ha mostrato che l’accelerazione massimale compare quando le considerazioni quantistiche cioè le relazioni di incertezza posizionemomento sono incorporate nella geometria di una particella nello spazio di fase a otto dimensioni La relazione d’incertezza tempoenergia è stata usata successivamente da Caianiello in una derivazione alternativa di accelerazione massimale La derivazione alternativa data nel 1984 è stata poi criticata da Sharma e Srirankanathan Qui si mostra che tale critica è infondata Si analizza anche la derivazione del 1984 di Caianiello Si trova che mentre l’accelerazione massimale segue da un’equazione dovuta a Landau e Lifshitz questa equazione non può essere trattata come una conseguenza della relazione d’incertezza tempoenergia
