We will talk about Quantum Thermalization and it's breakdown with Ivan Khaymovich from Nordita. See also this article and this video course by Mark Srednicki for more detailed information.

Mechanism of Thermalization

More details on the upcoming activity :
How do things thermalize?! With ordinary everyday intuition we know that a warm cup of coffee cools down to room temperature or something in contact with a warm stove heats up. Explaining thermalization on the quantum level is however very difficult! Over the last decade there has been a rapid growth in research focused on understanding thermalization from a microscopic point of view. The path of getting from the microscopic to the macroscopic is still not completely understood but one of the main theories is the ‘eigenstate thermalization hypothesis’ (ETH). Ivan Khaymovich, Assistant professor at Nordita, will explain why thermalization is difficult to understand microscopically from quantum mechanics and how ETH makes some headway in this direction. Welcome to our second (Fika and) News and Views of the term!

About News and Views :
Research in physics spans a wide range of topics from very tiny constituents of the universe like atoms, to big complex structures like galaxies. Each field of research has its own concepts, tools, and methods. We will leverage our knowledge from classrooms and textbooks to read “news and views” on highlighted research projects at the cutting edge of research. We will choose an article to discuss from an easily accessible source, keeping in mind the diversity of theoretical, experimental and numerical work that is a part of physics research work nowadays. In discussing these articles, we will try to discuss the big picture, rather than technical details. The format will be very informal and open-ended discussions are welcome! We hope these meetings will help all of us to broaden our view of physics, to find out what we are interested in and motivate us to do some research ourselves!

Schedule :

This term (Autumn 2023), we are planning to continue having two sessions a month. As we have been doing recently, we will have presentations on new and exciting research topics that we work on here at Stockholm University and Nordita. All sessions will be hybrid in Mega (or another available room in Albanova) + Zoom !
