Generalization of electrical resistance scaling to Dirac fields on perforated fractals
Jonathan F. Schonfeld
I construct perforated, "take-away" fractals that support short-distance power-law scaling with complex exponents for Dirac (spin-1/2) propagators. The construction relies on a for…
Does the Mott problem extend to Geiger counters?
Jonathan F. Schonfeld
The Mott problem is a simpler version of the quantum measurement problem that asks: Is there a microscopic physical mechanism - based (explicitly or implicitly) only on Schroedinge…
Test of a theory of the Mott quantum-measurement problem
Jonathan F. Schonfeld
The Mott problem asks: Is there a microphysical mechanism - based only on Schroedinger's equation - that explains why an alpha particle emitted in a spherically symmetric nuclear d…
Measured distribution of cloud chamber tracks from radioactive decay: a new empirical approach to investigating the quantum measurement problem
Jonathan F. Schonfeld
Using publicly available video of a diffusion cloud chamber with a very small radioactive source, I measure the spatial distribution of where tracks start, and consider possible im…
The first droplet in a cloud chamber track
Jonathan F. Schonfeld
In a cloud chamber, the quantum measurement problem amounts to explaining the first droplet in a charged-particle track; subsequent droplets are explained by Mott's 1929 wave-theor…
Analysis of double-slit interference experiment at the atomic level
Jonathan F. Schonfeld
I argue that the marquis characteristics of the quantum-mechanical double-slit experiment (point detection, random distribution, Born rule) can be explained using Schroedinger's eq…
Physical model of dimensional regularization
Jonathan F. Schonfeld
We explicitly construct fractals of dimension 4-epsilon on which dimensional regularization approximates scalar-field-only quantum-field-theory amplitudes. The construction does no…
