SEMINAR:
  The Action Principle: From Virgil's Aeneid to Quantum Walks
  - Variational principles in physics break new ground

Gareth Jay is a PhD student currently enrolled at UWA. Attached to the Quantum Information, Simulation and Algorithms research group, Gareth’s PhD research is focused on using a tool from quantum information theory known as quantum walks to simulate the Dirac equation on various discrete spacetime lattices. 
Variational principles have proven to be surprisingly fertile in
physics. The principle of stationary action originally arising out of a
derivation of optics and mechanics, remains central in modern physics
being applied to fluid mechanics, the theory of relativity, quantum
mechanics, and even string theory. In this talk we take a walkthrough of
the various extensions of the principle encompassing many fields of
physics before arriving at a new extension into the realm of discrete
time quantum walks that in their continuous limit match the Dirac
equation from quantum field theory.
