Moiré Than Meets the Eye: Uncovering the Quantum Potential of Phasons
(newscenter.lbl.gov)
Researchers have discovered that phasons, low-temperature quasiparticles found in crystal lattices, enable interlayer excitons to move at very low temperatures, when motion should stop.

Did the Particle Go Through the Two Slits, or Did the Wave Function?

What is really going on in the quantum double-slit experiment? The question raised in this post’s title seems to lie at the heart of the matter.

Quantum Milestones, 1964: John Stewart Bell Rings in New Era of Quantum Theory (2022)
(physics.aps.org)
In 1964, Bell showed that quantum physics predicts correlations that violate certain inequalities. The work implied that quantum mechanics is not compatible with locality, even if there were “hidden variables” not accounted for in quantum theory.

Hydrogen becomes a superfluid at nanoscale, confirming 50-year-old prediction

Hydrogen nano-clusters at low temperatures display 'superfluidity'—a quantum state of frictionless flow only previously observed in helium.

Opposing arrows of time can theoretically emerge from certain quantum systems
(surrey.ac.uk)
What if time is not as fixed as we thought? Imagine that instead of flowing in one direction – from past to future – time could flow forward or backward due to processes taking place at the quantum level. This is the thought-provoking discovery made by researchers at the University of Surrey, as a new study reveals that opposing arrows of time can theoretically emerge from certain quantum systems.

Conciousness May Be Retrocausal

In the quantum realm, the past, present, and future blur into a boundless structure. But consciousness may operate on a plane beyond this timeless mist.

How Hans Bethe stumbled upon perfect quantum theories
(quantamagazine.org)
By 1928, quantum physicists seemed poised to unravel matter’s final secrets. The German researcher Walter Gordon had applied the emerging theory of quantum mechanics to the hydrogen atom, the universe’s simplest atom, and worked out exactly how it behaved. A mastery of all atoms seemed sure to follow.

The Curious Similarity Between LLMs and Quantum Mechanics

Six months ago, I did a deep dive to understand the transformer architecture and noticed something strange: the concepts behind these models strangely mirror many features and phenomena from quantum mechanics.

Why even physicists still don't understand quantum theory 100 years on

Quantum mechanics depicts a counter-intuitive reality in which the act of observation influences what is observed — and few can agree on what that means.

Schrödinger's Cat and Heisenberg's Cut
(jimbaggott.substack.com)
There are at least two kinds of Schrödinger’s cat. There is Schrödinger’s cat parody or paradox, short details of which the physicist Erwin Schrödinger published in the German scientific journal Naturwissenschaften in 1935. And there is a Schrödinger’s cat of popular culture.

Physicists spot quantum tornadoes twirling in a ‘supersolid’
(quantamagazine.org)
In a lab nestled between the jagged peaks of the Austrian Alps, rare earth metals vaporize and spew out of an oven at the speed of a fighter jet. Then a medley of lasers and magnetic pulses slow the gas nearly to a halt, making it colder than the depths of space. The roughly 50,000 atoms in the gas lose any sense of identity, merging into a single state.

How fast is quantum entanglement? Scientists investigate it at attosecond scale
(phys.org)
Quantum theory describes events that take place on extremely short time scales. In the past, such events were regarded as 'momentary' or 'instantaneous': An electron orbits the nucleus of an atom—in the next moment it is suddenly ripped out by a flash of light. Two particles collide—in the next moment they are suddenly 'quantum entangled.'

John Wheeler saw the tear in reality

When Johnny Wheeler was 4 years old, splashing in the bathtub in Youngstown, Ohio, he looked up at his mother and asked, “What happens when you get to the end of things?” The question would haunt him for the rest of his life.

Are there individual protons and neutrons in a nucleus?
(stackexchange.com)
The popular science material always talks about the number of protons and neutrons in a nucleus, but I've always wondered if that's a real thing nuclear physicists believe or if it is just a convenient model.
