Extensive recent advances have been made on the topic of strange metals, which characterize the physics of strongly correlated systems that goes beyond the standard description in terms of quasiparticles. This workshop will bring together physicists working on this subject in a variety of platforms, with the aim of cross-fertilization. The platforms to be covered include:
- Copper- and iron-based high-temperature superconductors
- Heavy-fermion metals
- Metallic systems in proximity to quantum spin liquids
- Moiré structures
- Ultracold atomic systems
One focus of the workshop is to survey the prominent strange-metal properties. These include a scale-invariant spectrum illustrated by a dynamical Planckian (ℏω over kBT) scaling, a T-linear electrical resistivity, striking singularities in thermodynamic quantities and, often, an accompanying “large” to “small” Fermi-surface reconstruction with implications for a localization-delocalization transition. Another focus concerns how the amplified quantum fluctuations of the strange metals drive the formation of novel phases, with high-temperature superconductivity being the most notable candidate. Theoretical understandings based on exotic metallic quantum criticality will be discussed. Potential connections to black holes through the holographic correspondence will also be examined. The workshop promises to set future directions of research for this foundational topic of quantum condensed matter physics.

Summer Workshops
The summer program, running for 16 weeks from late-May to mid-September, emphasizes exciting open problems at the cutting edge. Two or three concurrent workshops, each with a specific focus selected for timeliness and the potential for breakthroughs and of two to five weeks in length, establish the main themes of each week, with twelve or thirteen different workshops each summer, balanced across fields including particle physics, string theory, astrophysics and hard and soft condensed matter physics, as well as emerging areas including biological physics, ultra-cold atom physics, quantum information, and physical mathematics. Additional researchers participate in small working groups or as individual researchers. This framework is designed to maximize informal interactions and free discussion within each area and to promote cross-fertilization between different areas via the common language of theoretical physics. Participation in the summer program of the Aspen Center for Physics is by application and subsequent invitation only. View past workshops.
