The Physics Behind Symmetrization

R. E. Kastner

It is often asserted that quantum states for same-type particles must be symmetrized due to ``label redundancy,'' i.e. the assumption that the permutations of labels in direct-prod…

Cosmology from Transactional Entropic Gravity: A Concise Review

R. E. Kastner, Andreas Schlatter

This is a review of key aspects of a model presented at the Lake Como School: Dark Matter, Dark Energy, and the Cosmological Tensions, June, 2025. The associated publication can be…

Where Photons Have Been: Nowhere Without All Components of Their Wavefunctions

R. E. Kastner

A nested interferometer experiment by Danan et al (2013) is discussed and some claims evaluated concerning the whereabouts of the photon, primarily in the context of time-symmetric…

Maxwell's Demon Is Foiled by the Entropy Cost of Measurement, Not Erasure

R. E. Kastner

I dispute the conventional claim that the second law of thermodynamics is saved from a "Maxwell's Demon" by the entropy cost of information erasure, and show that instead it is mea…

A Model of Entropy Production

Andreas Schlatter, R. E. Kastner

A key tenet of the Transactional Interpretation of Quantum Mechanics is the idea that photon absorption localizes the absorbing material system. In doing so, it measures the locati…

A Note on the Origin of Inertia

A. Schlatter, R. E. Kastner

The question of where the inertial properties of matter come from has been open for a long time. Isaac Newton considered inertia an intrinsic property of matter. Ernst Mach held a…

Entropy Cost of "Erasure" in Physically Irreversible Processes

R. E. Kastner, Andreas Schlatter

A restricted form of Landauer's Principle, independent of computational considerations, is shown to hold for thermal systems by reference to the joint entropy associated with conju…
