Hidden Variables and Nonlocality in Quantum Mechanics

There are essentially two reasons behind such doubts. The first concerns certain mathematical theorems ( ...

Algebraic Topology Foundations of Supersymmetry and Symmetry

Often physicists deal with such problems in terms of either spontaneous symmetry breaking or approximate symmetries that require underlying explanations or ad-hoc dynamic restrictions that are semi-empirical. A well-studied example of this kind is that of the dynamic Jahn–Teller effect and the corre ...
