Stripes, Planckian Dissipation and Quantum supremacy

The physics of Jan Zaanen

Zaanen Fest 2023

In July 2023, we celebrated Jan’s career in physics in style. For two days, we listened to a selection of Jan’s friends and “clones” in the Lorentz auditorium of the Kamerlingh Onnes building. Below are some pictures from the event. An overview of the scientific program is shown below.

Location venue:
Kamerling Onnes Building, University Leiden
Steenschuur 25, 2311 ES Leiden
