Imaging shapes of atomic nuclei in high-energy nuclear collisions

Atomic nuclei are self-organized, many-body quantum systems bound by strong nuclear forces within femtometre-scale space.

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.

Motivated by the mysteries of black holes, theorists are advancing their ability to describe space-time as a hologram.

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.

What Is a Particle? (2020)
(quantamagazine.org)
It has been thought of as many things: a pointlike object, an excitation of a field, a speck of pure math that has cut into reality. But never has physicists’ conception of a particle changed more than it is changing now.

Some remarks on the mathematical structure of the multiverse (2016)
(arxiv.org)
The Copenhagen interpretation of quantum entanglement experiments is at best incomplete, since the intermediate state induced by collapse of the wave function apparently depends upon the inertial rest frame in which the experiment is observed.

Coherent spin dynamics between electron and nucleus within a single atom
(nature.com)
The nuclear spin, being much more isolated from the environment than its electronic counterpart, presents opportunities for quantum experiments with prolonged coherence times.

Breaking Bell's Inequality with Monte Carlo Simulations in Python
(bytepawn.com)
In this article, we explore a game that challenges the very foundations of classical physics and introduces us to the strange world of quantum mechanics. The game involves three players — Alice, Bob, and Victor — who perform a series of experiments to test a fundamental principle known as Bell's theorem. By carefully selecting their measurement devices and analyzing the outcomes, Alice and Bob aim to determine whether the physical world can be explained by deterministic local hidden variables.
