Anthony James Leggett (born 26 March 1938) is a British-American theoretical physicist known for work on superfluidity, superconductivity, and macroscopic quantum systems.
Quantum context
Leggett's theory of superfluid helium-3 clarified how paired fermions can form a coherent quantum liquid with rich order-parameter structure. This work connected condensed-matter physics with broader ideas about symmetry breaking and quantum many-body states.
He also developed influential tests and models for macroscopic quantum behavior, including the Leggett-Garg inequality, making his work relevant to Physics:Quantum decoherence and the boundary between microscopic and macroscopic quantum phenomena.
