This post is about my ongoing physics research project. To tell a story (perhaps literally) which conceptually unpacks quantum field theory. That is, to develop a framework which: visualizes Wilczek’s Grid (discussed in other posts) and demystifies the historical tropes of quantum mechanics.
[Preliminary 11-11-2023] [“Quantum foundations” series] Table of contents Context This post was inspired by Don Lincoln’s latest YouTube video (below). Insights from quantum field theory (QFT) have helped me better understand strange aspects of quantum theory [1]. In particular, leaving behind notions of point particles and wave-particle duality, and just going with fields and wavepackets in… Continue reading Wavepackets and uncertainty principle
Thinking of the latest announcements for Nobel prizes: physics, chemistry, peace … Can the mind-boggling, awe-inspiring scale of the universe improve the odds of our collective survival? An expanding overview effect? “I believe our future depends powerfully on how well we understand this Cosmos in which we float like a mote of dust in the… Continue reading Island universe RIP – impact of awe-inspiring scales?
[“Quantum foundations” series – QFT charge inversion] As discussed elsewhere (e.g., in “QFT – How many fields are there?” and comments), in the Standard Model, “there is one field for each kind of particle.” So, consider the positron – the “negative-energy solution” of the Dirac equation. It’s likely that electrons and positrons (anti-electrons) are localized… Continue reading Does antimatter ‘fall’ the same as matter? – QFT and CPT symmetry

INTRODUCTION Remember pet rocks? So, what if someone gave you a gift, claiming it was even better than a Moon rock or Mars pebble. Something almost magical. An expensive novelty item. As advertised on TV: “Tangled Blocks” … go quantum! do Einstein spooky action! each block contains a particle entangled with one in the other… Continue reading The degree of entanglement – quantifying an entangled system
The incompleteness of relativity and quantum theories So, for me, there’s always been a nagging shortfall of visualization for the major theories of modern physics: Relativity and Quantum theories. Successful theories indeed. But a focus on the mathematics, with some hand-waving surrounding implicit assumptions (or definitions), conveying a flawless formulation in popular presentations. As discussed… Continue reading Special relativity’s fundamental defect – ether redux
Here’re some articles on advanced microscopy research, including quantum microscopy by coincidence. Not included (as yet) below is an article about nano fab of crystal lattices – direct deposition of individual atoms at lattice sites vs. more conventional doping (impurity) techniques. 1 . Studying ultrafast molecular dynamics • Phys.org > “Ultrafast X-ray spectroscopy: Watching molecules… Continue reading Imaging at the molecular and atomic level
When a photon excites an electron within plant chromophores [1], the transport of energy (without transporting net electric charge) resembles an exciton [2] condensate. “Chromophores … can pass energy between them in the form of excitons to a reaction center where energy can be used, kind of like a group of people passing a ball… Continue reading Quantum biology – excitons in plant chromophores
TABLE OF CONTENTS Alice & Bob et al. measure quantum states & wonder about predicting outcomes. In continuous quantum fields, localized disturbances (excitations) interact and exchange energy between fields – as real outcomes. “We suppress dimensions in order to make sense of things.” Modeling interactions of excitations with vacuum states of quantum fields gets weird.… Continue reading Reckoning quanta, quantum events – nostalgia for absoluteness?
