量子自旋链涨落代数

On the Algebra of Fluctuation in Quantum Spin Chains

Taku Matsui

摘要:

本文证明了混合量子自旋链中一对互不对易的算子的中心极限定理。算子不一定是严格局部的,而是准局部的。作为推论,我们得到了一维格点上有限程相互作用吉布斯态的正态涨落代数的时间演化的直接构造。证明了当微观态是$β$-KMS态时,正规涨落代数的态满足$β$-KMS条件.

英文摘要:

We present a proof of the central limit theorem for a pair of mutually non-commuting operators in mixing quantum spin chains. The operators are not necessarily strictly local but quasi-local. As a corollary we obtain a direct construction of the time evolution of the algebra of normal fluctuation for Gibbs states of finite range interactions on a one-dimensional lattice. We show that the state of the algebra of normal fluctuation satisfies the $β$-KMS condition if the microscopic state is a $β$-KMS state.
