• タイトル：「Emergent phenomena in classical spin liquids」
• 概要　　：
Spin liquids are malleable magnetic textures obeying their own microscopic rules. These rules, due to frustrated constraints, can take the form of emergent gauge fields able to support quasi-particles, readily accessible by experimental probes.
In this talk we will illustrate the diversity of emergent phenomena supported by classical spin liquids, starting from the Coulomb gauge field of spin-ice materials. This Coulomb field can be for example confined in thin-film geometries, or serve as a foundation for exotic phases such as “fragmented” spin liquids where the fluctuating gauge field coexists with long-range order.
Beyond Coulomb gauge field, we will discuss how topological charges can persist in spin-liquid ground states by forming disordered clusters, and how other forms of gauge fields, reminiscent of linearized general relativity, can emerge in a crystal.
