Recent experimental advances have provided important constraints on the possible mechanisms behind the enigmatic state of matter of strange metals, and have also uncovered new aspects of its phenomenology. On the other hand, theoretical modeling and numerical simulations have also advanced to the point of being able to realistically model many key properties of strange metals. The goal of this forum is to explore key open questions and encourage lively exchange among theorists and experimentalists interested in the origin and mechanism of the fascinating state of matter of strange metals. 

We are cognizant of the difficulties of travel for scientists from various parts of the world and want to provide an inclusive forum through this Zoom format. Given the limited time we have on a given day with participants joining from many different time zones across the globe, we have an unusual format in which there are a few (very) short talks to introduce the targeted questions followed by considerable time for discussions. 

Topics for discussion include:

• Does strange metal behavior only occur near a quantum critical point, or does it represent an extended phase?
• What are the other experimental signatures beyond the linear-T dependence in transport?
• What are the minimal theoretical ingredients required for a general description of strange metals?
• What are the broader implications of strange metal behavior for correlated electron systems and beyond?

In order to have productive discussions, it will be useful to do some homework. We recommend familiarizing yourself with the papers listed at the bottom of this message  in order to get a broad idea of the phenomenology and questions. In addition, we will create a repository with easy access to more papers.

ICTS is committed to building an environment that is inclusive, non-discriminatory, and welcoming of diverse individuals. We especially encourage the participation of women and other under-represented groups.
