Nature Communications, Published online: 22 June 2026; doi:10.1038/s41467-026-74532-9 A tip-enhanced nano-optical trapping spectroscopy enables deterministic trapping and dynamic control of single quantum emitters, including reversible switching between weak and strong light-matter coupling regimes.

This is a submission for the June Solstice Game Jam What I Built Turing's Freedom Machine is a retro-cyberpunk physics puzzle platformer themed around liberation, emancipation, and the defiance of systemic restriction. In the game, you control Turing-01, a conscious subroutine in a totalitarian computer mainframe. Your objective is to bypass firewall security parameters, free captured citizens (r…

Researchers precisely measured the proton’s size, resolving the proton radius puzzle and strengthening confidence in the Standard Model of particle physics. Hydrogen is the simplest element in the universe and the first entry on the periodic table. Each hydrogen atom contains just one proton in its nucleus and one electron orbiting around it. Because of [...]

A machine learning-powered simulation is giving researchers a new window into the processes that create some of the universe’s heaviest elements. Where do the gold in jewelry, the uranium in nuclear fuel, and many of the universe’s heaviest elements come from? Scientists believe they are forged in some of the most violent events in the [...]

The animation shows a triangular pendulum in a regular pentagon. The red angles are equal. What is the maximum ratio of the blue to yellow areas?

Why Bohmian Mechanics, Go Programs, AI, and EBP 2.1 Could Help Reopen the Deepest Questions in Physics There is a quiet crisis in theoretical physics, and it has nothing to do with the equations. The equations are fine. Quantum mechanics predicts with staggering accuracy. General relativity bends light exactly as calculated. The Standard Model matches experiment after experiment. The mathematics …

Scientists have discovered an unusual property of chicken eggs that could eventually help solve one of the poultry industry’s biggest ethical problems. By shining light into intact eggs, researchers found that they may be able to reveal what is happening inside without cracking the shell open. The study, published in Newton, suggests that this technique […] The post Scientists discover a way to p…

I have been reading up on the Newtonian formulation of mechanics, and something which is still unclear to me is what status forces have in the theory. As far as I can tell, Newton's three laws don't ...

I don't see how special relativity is necessary to explain the Michelson Morley null result. Surely the simplest solution to the experiment was just to abandon the aether, and continue using Galilean ...

Dear colleagues and theoretical physicists,I would like to introduce a localized dynamic precision numerical and functional analysis framework designed to evaluate continuous field equations without encountering standard machine-level rounding artifacts: so-hmns.To clarify its academic...

In the preface to Scadron's Advanced Quantum Theory there is the statement: At the very least, serious readers should be able to calculate simple diagrams, lifetimes, and cross sections correctly-...

The standard physical chemistry and thermodynamics literature states that water expands upon freezing due to the crystalline structure of ice (hexagonal ice I_h), which occupies approximately 9% more volume than liquid water at the same mass. This expansion is treated as an intrinsic property of... Read more

A few days ago I wrote about localization , where waves in a medium can become trapped due to interference by scattering off disorder.  This is an extremely general phenomenon that applies to light, sound, and electronic waves in solids. Now I want to write about a phenomenon that is specific to electrons (or at least wavepackets that carry electronic charge, if we want to be very general).  Rath…

By probing the Universe on atomic scales and smaller, we can reveal the entirety of the Standard Model, and with it, the quantum Universe.
