Colloquium Schedule

Colloquium: Thursday, November 19, 4:10 PM, Lewis Lab 316

Spacetime Geometry and Quantum Control Theory

Gary Gibbons

Department of Applied Mathematics and Theoretical Physics
University of Cambridge

The aim of this talk is to relate a problem in quantum mechanics to a problem in general relativity, Fermat's principle, a variational problem of Zermelo, and some Finsler geometry. In other words I shall be applying some geometric ideas and methods used in general relativity to the quantum mechanics of systems with a finite dimensional Hilbert space. The talk is based on a recent paper: "Time-optimal navigation through quantum wind" with Dorje C. Brody and  David M. Meier (Brunel U.).  New J.Phys. 17 (2015) 3, 033048  arxiv: 1410: 6724.
