Extension of Lorentz Group Representations for Chiral Fermions
... The principles of quantum measurement are at the foundation of particle physics. For example, particle spin and momentum assignments are determined by quantum representations of the Lorentz group [1], and quantum electrodynamics as a local U (1) gauge theory emerges naturally from the phase invarian ...

Quantum Analysis on Time Behavior of a Lengthening Pendulum
... Much attention has been paid to the classical and quantum problems of the lengthening pendulum up to now. The time variation of angular and linear amplitudes has been analyzed by Brearley for a simple lengthening pendulum under the assumption that the amplitude of the oscillation is small [18]. The ...

The Indivisible Now: why time must be discrete. - Philsci

The nature of time as a timing mechanism13 is a more mechanical, arbitrary property, and not what I am considering here. Strictly speaking any entangled system ...
