Abstract:	我們計畫藉數值計算研究無序效應對處於非磁性態的量子磁鐵之影響。我們將探討無序誘發的「隨機價鍵態」是否呈現量子自旋液態之特徵。此外，我們也將探討無序關聯性任意子之動態行為。 We propose to numerically study the effects of quenched disorder on quantum magnet in which interactions or magnetic frustration promote the formation of short-ranged singlets. The purpose of this study is to clarify whether random-singlet states induced by randomness in valence-bond solids and in frustrated magnets exhibit signatures for quantum spin liquid. Furthermore, we will study disorder effects on dynamical properties of interacting anyons, which are emergent quasiparticles in certain quantum spin liquids.
