Exceptional quantum geometry and particle physics

Remarks on Quantum Physics and Noncommutative Geometry

The quantum-event / prime ideal in a category/ noncommutative-point alternative to classical-event / commutative prime ideal/ point is suggested. Ideals in additive categories, prime spectra and representation of quivers are considered as mathematical tools appropriate to model quantum mechanics. The space-time framework is to be reconstructed from the spectrum of the path category of a quiver....

Topology, Quantum Gravity and Particle Physics

It is argued that quantum gravity has an interpretation as a topological quantum field theory provided a certain constraint from the path integral measure is respected. The constraint forces us to couple gauge and matter fields to gravity for space time dimensions different from 3. We then discuss possible models which may be relevant to our universe.

Doing Physics with Matlab Quantum Physics Wave Particle Duality

diffraction_particle.m Animation of the diffraction of a stream of particles passing through a double slit (Figures 3, 4). The (xP, yP) coordinates of a point P on the detector screen are chosen at random. The irradiance IRRP at the point P with x coordinate xP is calculated using Equation (2). The irradiance is scaled so that its maximum value is 1 when at x = 0. Another random number SP is ge...

Quantum Physics: A Case for Anti-Realism?

Wigner Particle Theory and Local Quantum Physics Lucio

Wigner’s theory of positive energy representations of the Poincaré group has been often used to give additional justifications for the Lagrangian quantization approach to QFT. Here we show that by extension with a modular localization structure it can directly lead to the net of local algebras without the use of any pointlike field-coordinatization. The same modular methods reveal that among th...
