Ms Gwendolyn Barnes (University of Pretoria)

Would you like to <br> submit a short paper <br> for the Conference <br> Proceedings (Yes / No)?


Level for award<br>&nbsp;(Hons, MSc, <br> &nbsp; PhD)?

Abstract content <br> &nbsp; (Max 300 words)

The concept of equilibrium in dynamical quantum mechanical systems is expressed in the mathematically rigorous formalism of operator algebras. The equilibrium state of the canonical ensemble at inverse temperature &beta can be characterised as a state over the C-algebra of observables which satisfies the KMS boundary condition for the one-parameter -automorphism group derived from the notion of time evolution in the Heisenberg picture of quantum mechanics.
