Description

Title: Equations of Motion for Spin Nematics or How do Spins celebrate Valentine's day?

Speaker: Kimberly Remund, Theory of Quantum Matter Unit

Abstract: In this internal seminar, I will talk about what makes Spin Nematics such an attractive research area. I will give a preliminary overview of the field reviewing the basic, but not necessarily trivial, concepts:
Is Quantum Theory the latest dating app using a revolutionary algorithm based on quantisation of the user’s data?
Is Spin the new speed-dating process where people form radial pairs facing each other, drawing a 2-rings circle and where people spin around in the inner ring to switch partners?
I will try to charmingly and rigorously explain how Spins can unconventionally order into a Spin Nematic and what makes them so mysterious. We will then decode the nuptial dance of Spin Nematics by calculating the Equations of Motion. This teaches us about the evolution in time of their behaviour. In order to characterise the spin nematic state, we will look for what the footprint of such a state should look like by studying its excitations. Finally, we will appreciate the beauty of topological defects in spin nematics.
