Question
Transcribed Image Text:Problem Statement:
In quantum field theory, observables are often represented by operators in a non-commutative
algebra. Let A be a non-commutative C*-algebra of observables acting on a Hilbert space H, and let
be a state on A.
1. Non-Commutative Spectral Measures: Define what constitutes a spectral measure in the non-
commutative setting of A, and construct such measures for self-adjoint elements of A.
2. Measure-Theoretic States and Spectral Integration: Prove that states induce measure-
theoretic structures on the spectral measures of observables, and demonstrate how spectral
integration can be performed with respect to these states.
3. Quantum Field Theory Applications: Apply the developed spectral measure framework to
analyze specific observables in quantum field theory, proving results about the distribution of
measurement outcomes and the entanglement properties encoded in the spectral measures.
Requirements:
•
Extend spectral measure concepts to non-commutative operator algebras.
•
Utilize states on C*-algebras to induce measure-theoretic structures.
Apply the theory to practical problems in quantum field theory.
