2024 is here - 30 years of Eigenstate Thermalization

12. January 2024

In 1994, Mark Srednicki published a paper on the origin of thermalization in isolated quantum many-body systems. Nowadays, this work is regarded as a landmark paper and has opened a new research area for many physicists (including myself). In this blog post, I provide a brief introduction to the so-called Eigenstate Thermalization Hypothesis, and provide my personal perspective on some recent developments.

Simulating quantum transport in closed and open quantum systems

20. October 2023

In a series of two papers (see here and here), my colleagues and I tried to connect the dynamics of closed and open quantum systems. In particular, we establish a new connection between closed-system linear-response correlation functions and the open-system dynamics described by Lindblad quantum master equations with weak system-bath coupling.

Hydrodynamics in long-range systems with kinetic constraints

18. May 2023

In the last few months, together with my collaborators Alan Morningstar and Nick O'Dea, we worked on a project studying the competition of long-range interactions and center-of-mass conservation, and their impact on transport properties of many-body systems. We published a paper that can be found on the arXiv.

California, Casino, and Clifford circuits

20. March 2023

In this blog post, I write about the rainy Californian winter, my time at the APS March Meeting in Las Vegas, and my research on random circuits that I recently published and presented in a talk.

Looking back on 2022

19. December 2022

Christmas is around the corner and another busy year is coming to an end. I was fortunate to visit several exciting conferences and workshops and also managed to publish several manuscripts together with my collaborators.

Moving to California as a Marie Curie Fellow

14. November 2022

Earlier this year, I was notified that my application for a Marie Skłodowska-Curie Postdoctoral Fellowship was successful, which will provide funding for my research for the next 2.5 years. This opens up the great opportunity to conduct research at Stanford University during the first phase, as well as at Leibniz Universität Hannover during the second phase. In this blog post, I write about my move from London to the US, tell you about some details of my Marie Curie project, and share some thoughts about the first two weeks in my new position.
