The characteristic excitation of a metal is its plasmon, which is a quantized sound wave in its valence electron density.…

Kinematically, massless particles in Lorentz-invariant theories are classified by a dimensionful "spin scale"ρ (2nd Casimir invariant) that characterizes helicity states' mixing under little group…

It has recently been shown that any Euclidean gravitational path integral satisfying a simple set of axioms defines type I von Neumann algebras of bulk observables acting on compact closed…

There are a variety of experimental and astrophysical constraints on non-gravitational interactions of dark matter, both with itself and with the Standard Model.

Does commutation imply factorisation? More precisely, consider two parties, Alice and Bob, each of whom applies an operation on a shared quantum system, K.
