量子自旋液体

Quantum spin liquids

Gregoire Misguich

摘要:

本文介绍了量子自旋液体领域中的几个理论观点:经典零模和1/S展开的破缺,Lieb-Schultz-Mattis-Hastings定理和Oshikawa的论证,短程共振价键图象,大N极限(Schwinger玻色子)和Z_2规范理论。

英文摘要:

These notes are an introduction to a few selected theoretical ideas in the field of quantum spin liquids: classical zero modes and breakdown of the 1/S expansion, the Lieb-Schultz-Mattis-Hastings theorem and Oshikawa's argument, the short-ranged resonating valence-bond picture, large-N limit (Schwinger bosons) and Z_2 gauge theory.
