The past few decades have seen tremendous progress in the study of quantum materials with strongly correlated electrons, both in theory and in experiment. At the same time, many important challenges remain. We still lack a full theory of high-temperature superconductivity and the adjacent strange metal phase. New materials are being discovered, including twisted van der Waals heterostructures, which experimentally probe regimes requiring new theoretical frameworks.

This school focuses on some of the profound and long-standing challenges and mysteries in the field of correlated quantum materials, and covers both theoretical and experimental advances. Experimental topics include the quantum chemistry of correlated electron systems, to novel platforms such as Moiré materials, to state-of-the-art techniques to detect quasiparticles (or the lack thereof) in material systems. Theoretical topics will include transport and hydrodynamic theory, quantum phase transitions and superconductivity, application of quantum field theory methods to correlated metals, and computational method.

The Boulder Summer School in Condensed Matter and Materials Physics has been established to provide education for advanced graduate students and postdocs working in frontiers of condensed matter physics, materials science and related fields. The goal is to enable students to work at the frontiers of science and technology by providing expert training not easily available within the traditional system of graduate education and postdoctoral apprenticeship. The School is supported by the National Science Foundation, with additional funding provided by the University of Colorado, and meets annually during July at CU Physics Department, Boulder, Colorado.
