CPT Student Seminar: The Energy-Momentum Tensor

Presented by Alan Reynolds, Durham University

31 October 2016 17:00 in OC218

Rather than discuss my recent research, I will return to a topic from the first term's CPT lectures that caused me much confusion in my MSc year at Durham: the energy-momentum tensor. Starting with what this tensor actually is and why we need such a tensor, I will (hopefully) clarify its canonical definition as a Noether current and give additional detail regarding the use of and differences between 'active' and 'passive' transformations. I will then consider alternative definitions of the energy-momentum encountered later in the lectures and explore the relationships between these energy-momentum tensors.

The first part of the talk will be aimed at MSc and first year PhD students who should have recently encountered the energy-momentum tensor in lectures, with later parts suitable for anyone who, like me, still has questions regarding this bothersome object.

A gathering of mathematicians from the CPT group with physicists from IPPP, we meet to discuss our work in a relaxed and friendly environment.
