Emergence of classicality states that a quantum description of a large object must be the same as its classical description, but this isn’t always so…
From wood chuck holes to worm holes — A look into the notebooks of John Wheeler
Glimpse into the notebooks of physicist John Wheeler, which capture his eclectic, crazy, and yet never one-dimensional ideas.
How is spacetime altered by entangled particles?
A new thought experiment explores the interface between quantum mechanics and general relativity using the transfer of information.

The local conductivity in bismuth ferrite thin films with well-ordered domain walls.
Curvature Changes Quantization Procedure
A theoretical puzzle has existed for over half a century: how to perform quantization for a particle constrained to remain on the curved surface with Dirac’s canonical quantization scheme? The answer has been found.
