KelvinHelmholtz instability is the result of paritytime symmetry breaking
Abstract
ParityTime (PT)symmetry is being actively investigated as a fundamental property of observables in quantum physics. We show that the governing equations of the classical twofluid interaction and the incompressible fluid system are PTsymmetric, and the wellknown KelvinHelmholtz instability is the result of spontaneous PTsymmetry breaking. It is expected that all classical conservative systems governed by Newton's law admit PTsymmetry, and the spontaneous breaking thereof is a generic mechanism for classical instabilities. Here discovering the PTsymmetry of systems in fluid dynamics and plasma physics and identifying the PTsymmetry breaking responsible for instabilities enable new techniques to classical physics and enrich the physics of PTsymmetry.
