The Quantum Mystery of Wigner's Friend

In this Insight I will introduce the quantum mystery called ``Wigner's friend'' using Healey's version [1] of Frauchiger and Renner's (FR's) version [2]…

The Unreasonable Effectiveness of the Popescu-Rohrlich Correlations

In this Insight, I will show how the Popescu-Rohrlich (superquantum) correlations provide an unreasonable advantage in a particular "quantum guessing game''…

Spectral Standard Model and String Compactifications

 The Connes-Lott-Chamseddine-Barrett model is the observation that the standard model of particle physics -- as a classical action functional,…

Tools to Enrich our Quantum Mechanics Interpretations Discourse

IntroductionMany times, we encounter ourselves tangled into some Quantum Mechanics (QM) interpretations debates. Unfortunately, the standard…

Examples of Prequantum Field Theories III: Chern-Simons-type Theories

  After having constructed gauge fields and higher gauge fields in the previous article by systems of ##L_\infty##-algebroid-valued…

Does the Heisenberg Uncertainty Principle Imply Energy Nonconservation?

The short answer is: no, there's no violation.The longer answer can be this: Given the probabilistic aspect of quantum theory, what do we mean now,…

Some Useful Integrals In Quantum Field Theory

In my paper on renormalisation I mentioned what most who have studied calculations in Quantum Field Theory find, its rather complicated and mind numbing.…

Some Sins in Physics Didactics

Introduction There are many sins in physics didactics. Usually they occur, because teachers, professors, textbook or popular-science-book writers, etc.…
