Causality and Propagators in QFT
Causality Causality in QFT requires that events or measurements that are space-like separated (, events that cannot influence each other) do not affect each other. This is formalized by ensuring…
States as Functionals in QFT
States as Functionals in QFT Functionals depend on the ENTIRE space configuration for a system. This implies an inherent non-locality for the state. This should be true for all 3…
Non-locality in the Heisenberg Representation
Non-locality in the Heisenberg Representation Non-locality is a fundamental aspect of quantum field theory (QFT) and it arises in both the Schrödinger and Heisenberg representations. Here’s an explanation of how…
Bohm’s Quantum Potential Approach
Bohm's quantum potential approach, also known as the de Broglie-Bohm interpretation or Bohmian mechanics, is an alternative formulation of quantum mechanics that provides a deterministic framework. Here are the key…
Quantum Strategies in Classical Games – Monty Hall
From the paper - Quantum version of the Monty Hall problem Flitney , D. Abbott Centre for Biomedical Engineering (CBME) and Department of Electrical and Electronic Engineering, Adelaide University, SA…
The Monster Group in mathematics
The Monster Group, often referred to as the "Monster" or M\mathbb{M}M, is the largest sporadic simple group in mathematics. It plays a significant role in the field of group theory,…
Compactified versus non compactified Kaluza-Klein Theories
Kaluza-Klein Gravity - by J. M. Overduin and P. S. Wesson Compactified Kaluza-Klein Theories Definition and Mechanism: In compactified Kaluza-Klein theories, the extra dimensions are curled up into very small…
Kaluza-Klein theory and general relativity
The relationship between Kaluza-Klein theory and general relativity is a foundational aspect of the former. Kaluza-Klein theory extends general relativity by incorporating additional dimensions beyond the familiar four-dimensional spacetime. Here…
Why Hilbert Space in Quantum Mechanics?
Heisenberg's matrix mechanics and Schrödinger's wave mechanics - have a common underlying mathematical structure. That common structure is Hilbert space. These two theories are said to be isomorphic. If you…
Gravitational Redshift, Inertia, and the Role of Charge
The document titled "Gravitational Redshift, Inertia, and the Role of Charge" by Johannes Fankhauser and James Read explores several nuanced aspects of gravitational redshift and related phenomena. Here is…
