New quantum theory of gravity brings 'theory of everything' step closer
(phys.org)
At long last, a unified theory combining gravity with the other fundamental forces—electromagnetism and the strong and weak nuclear forces—is within reach.

Casimir Effect
(wikipedia.org)
In quantum field theory, the Casimir effect (or Casimir force)[1] is a physical force acting on the macroscopic boundaries of a confined space which arises from the quantum fluctuations of a field.

Across the observable Universe, there are some 10^80 atoms, and most of them are simple hydrogen: made of just one proton and one electron each.

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.

Quantum calculations amount to sophisticated estimates. But in 1931, Hans Bethe intuited precisely how a chain of particles would behave — an insight that had far-reaching consequences.

Frequency shifts do not imply quantum entanglement (2022)
(benbrubaker.com)
I’ve somehow become the go-to twitter critic (jointly with Douglas Natelson, a Rice University physics professor with an excellent blog) of a recent unpublished manuscript that has generated a lot of premature press coverage. The authors of this paper claim to have demonstrated quantum entanglement between a superconducting qubit — a special kind of electrical circuit that exhibits quantum behavior — and a remarkably hardy little creature called a tardigrade.

Scientists observe 'negative time' in quantum experiments

Scientists have long known that light can sometimes appear to exit a material before entering it—an effect dismissed as an illusion caused by how waves are distorted by matter.

Quantum scars make their mark in graphene

By patterning an ultrathin layered structure with tiny wells, physicists have created and imaged peculiar states known as quantum scars — revealing behaviour that could be used to boost the performance of electronic devices.

Physicists Reveal a Quantum Geometry That Exists Outside of Space and Time
