Workshop Overview

  Welcome to the workshop “Novel Physics in Kagome Lattice Materials,” to be held at the Yukawa Institute for Theoretical Physics (YITP), Kyoto University, from October 5 to 8, 2026. Following the successful international workshops on kagome lattice materials held in 2024 and 2025 at KITS, CAS in Beijing, this workshop at YITP will focus on the latest theoretical and experimental advances in both magnetic and nonmagnetic kagome lattice materials.

  The electronic band structure of kagome metals exhibits three prominent features: a “flat band” with effectively infinite mass, “Dirac points” with zero effective mass, and “van Hove singularities” at specific momenta where the effective mass diverges. When strong electron correlations and spin–orbit interactions are present, various phenomena can emerge, including the quantum anomalous Hall effect and topological superconductivity, accompanying the spontaneous loop current that break time-reversal symmetry. As a result, new aspects of quantum physics continue to be uncovered.

  In “kagome semimetals”, Weyl semimetal phases have been discovered, and nontrivial topological properties associated with Berry curvature, such as large anomalous Hall effects, magnetoresistance, and surface Fermi arcs, have been reported.

  Furthermore, in “kagome spin systems”, recently discovered ideal kagome materials with minimal disorder have significantly advanced the study of quantum spin liquid states. In particular, substantial progress has been made on long-standing issues of nearly half a century, including the presence or absence of a zero-field gap and the discovery of novel magnetization plateau.

  This conference will invite leading researchers from around the world to share the latest theoretical and experimental results, to clarify open problems in the field, and to discuss future research directions. It will also promote international collaboration among different research communities, including strongly correlated electron systems, topological quantum materials, and advanced measurement techniques, thereby contributing to further development of the field.
