The theory of explicitly time‐dependent invariants is developed for quantum systems whose Hamiltonians are explicitly time dependent. The central feature of the discussion is the derivation of a simple relation between eigenstates of such an invariant and solutions of the Schrdinger equation. As a ...
However, since the beginning of quantum theory it would be possible to realize that the circumstances in nature are exactly the other way round. The idea "smaller becomes simpler" is useful only down to the atoms of chemistry. Planck's formula shows that smaller extensions are related to ...
Both the connection and loop space representations for the quantum theory are considered. We find that the physical state space has a characterization in terms of equivalence classes of Eulerian graphs.关键词: Theoretical or Mathematical/ quantum field theory of gravitation space-time configurations/ ...

Quantum theory of clock 07是这个路径积分诠释的精髓,它提醒我们叠加态原理可能是更基本的原理的一个仅仅在少体系统里适用的近似。我猜这条路走下去可能会解决基于哥本哈根诠释的退相干理论没解决完的随机性问题,下面我脑补了一个可能的具体解释[微笑] 这个诠释里时间是衍生量(只能在有宏观系统参与的过程中被定义...
Many have suggested that the transformation standardly referred to as time reversal in quantum theory is not deserving of the name. I argue on the contrary that the standard definition is perfectly appropriate and is indeed forced by basic considerations about the nature of time in the quantum for...
Time-Symmetrized Quantum Theory: A Critique This dissertation considers various claims which have been made by proponents of time-symmetrized quantum theory (TSQT), focusing in particular on the work of Lev Vaidman, who has been the strongest advocate in recent years. These claims... RE Kastner...
Available for the first time in paperback, The Quantum Theory of Fields is a self-contained, comprehensive, and up-to-date introduction to quantum field theory from Nobel Laureate Steven Weinberg. Volume I introduces the foundations of quantum field theory. The development is fresh and logical thr...
Quantum theory provides an extremely accurate description of fundamental processes in physics. It thus seems likely that the theory is applicable beyond the, mostly microscopic, domain in which it has been tested experimentally. Here, we propose a Gedank
