Institute Online Colloquium - Dr. Steven Thomson - The Physics of Spin Glasses - 29th October 2021

IIT Mandi Institute Online Colloquium
“A Journey Into Disorder & Frustration: The Physics of Spin Glasses”
Speaker - Dr. Steven J. Thomson,
Marie S.-Curie Fellow, Freie Universität Berlin.
Date - 29th October 2021, 1400 hrs onwards
Abstract
One half of the 2021 Nobel Prize in Physics was awarded to Giorgio Parisi for his discovery of ‘hidden patterns in disordered complex materials’ which ‘make it possible to understand and describe many different and apparently entirely random materials’. But what does this really mean? Spin glasses are highly complex, intricate phases of matter which push our mathematical and computational techniques to their limit: fully understanding them remains a major open problem at the frontier of fundamental physics. In this talk, I will discuss the physics of spin glasses, describe how the insights of Parisi and collaborators opened the door to our modern understanding of these enigmatic magnetic phases, as well as how these techniques connect to modern fields as diverse as neural networks and machine learning. Finally I will outline some outstanding challenges in this highly active field, including my own research into potential links with many-body localization and applications towards quantum computing.
About the speaker
Dr Steven J Thomson is currently a Marie Skłodowska-Curie Fellow at Freie Universität Berlin on the European Commission project ‘Ergodicity Breaking in Quantum Matter’, working in the group of Prof. Jens Eisert.
He has previously been a postdoctoral researcher at Collège de France working with Dr Marco Schiró, postdoctoral researcher at the Centre de Physique Théorique, École Polytechnique, working with Prof. Laurent Sanchez-Palencia, and the Institut de Physique Théorique (CEA Paris-Saclay), also working with Dr Marco Schiró. His main research interests are the non-equilibrium dynamics of strongly correlated quantum systems in the presence of quenched random disorder, particularly many-body localisation and quantum glasses. He is currently particularly interested in developing cutting-edge numerical methods, with a focus on unitary flow techniques and tensor networks. He lives and works in Berlin, Germany.

amazing lecture

Can spin glasses ever form magnons

At 20:47 you said the green line is -J and red line is +J . But according to your assumption at 16:20 , the parallel alignment will give to negative energy . How come the first green line on first row is giving -J although they have antiparallel alignment ?

I would guess he’s moved back to the field lattice and is defeated the problem of location
