翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Quantum spin liquid ： ウィキペディア英語版 Quantum spin liquid In condensed matter physics, quantum spin liquid is a state that can be achieved in a system of interacting quantum spins. The state is referred to as a "liquid" as it is a disordered state in comparison to a ferromagnetic spin state, much in the way liquid water is in a disordered state compared to crystalline ice. However, unlike other disordered states, a quantum spin liquid state preserves its disorder to very low temperatures.〔 The quantum spin liquid state was first proposed by physicist Phil Anderson in 1973 as the ground state for a system of spins on a triangular lattice that interact with their nearest neighbors via the so-called antiferromagnetic interaction. Quantum spin liquids generated further interest when in 1987 Anderson proposed a theory that described high temperature superconductivity in terms of a disordered spin-liquid state. A quantum spin liquid state in κ-(BEDT-TTF)2Cu2(CN)3 was first thoroughly mapped using muon spin spectroscopy by a team led by Dr Francis Pratt at ISIS neutron source, UK in March, 2011.〔(【引用サイトリンク】url=http://www.isis.stfc.ac.uk/science/physics/magnetism/quantum-mapmakers-complete-first-voyage-through-spin-liquid11788.html )〕 ==Examples== Several physical models have a disordered ground state that can be described as a quantum spin liquid. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Quantum spin liquid」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
