Is There a Quantum Mechanics Framework Without Hilbert Space?

Click For Summary
SUMMARY

The discussion centers on the exploration of a quantum mechanics framework that operates independently of Hilbert space, as proposed by B. J. Hiley in his article "Algebraic Quantum Mechanics, Algebraic Spinors and Hilbert Space." Hiley demonstrates that the quantum mechanical wave function, density operator, and mean values can be derived solely from the orthogonal Clifford algebra and generalized Clifford algebra, C^n. The GNS construction is also shown to be attainable within these algebras, with the limit of C^n as n approaches infinity corresponding to the extended Heisenberg algebra, thereby challenging the conventional Hilbert space approach.

PREREQUISITES
  • Understanding of quantum mechanics principles
  • Familiarity with algebraic structures, specifically Clifford algebras
  • Knowledge of the GNS construction in quantum theory
  • Basic concepts of the Heisenberg algebra
NEXT STEPS
  • Research the implications of algebraic quantum mechanics on traditional quantum theories
  • Study the properties and applications of Clifford algebras in physics
  • Examine the GNS construction and its relevance in quantum mechanics
  • Explore the extended Heisenberg algebra and its significance in quantum theory
USEFUL FOR

Physicists, quantum mechanics researchers, and mathematicians interested in alternative frameworks for understanding elementary particles and quantum theory without reliance on Hilbert space.

Is anyone out there working on a theory of elementary particles that is basic quantum mechanics without the Hilbert space? The reason I'm asking is because I found this article by B. J. Hiley:

Algebraic Quantum Mechanics, Algebraic Spinors and Hilbert Space.
The orthogonal Clifford algebra and the generalised Clifford algebra, [tex]C^n[/tex], (discrete Weyl algebra) is re-examined and it is shown that the quantum mechanical wave function (element of left ideal), density operator (element of a two sided ideal) and mean values (algebraic trace) can be constructed from entirely within the algebra. No appeal to Hilbert space is necessary. We show how the GNS construction can be obtained from within both algebras. The limit of [tex]C^n[/tex] as [tex]n \to \infty[/tex] is shown to be the extended Heisenberg algebra. Finally the relationship to the usual Hilbert space approach is discussed.
