Lie-Nambu方程解的密度矩阵解释
Density matrix interpretation of solutions of Lie-Nambu equations
摘要:
如果密度矩阵$ρ(t)$是一个非线性三括号方程的自伴和Hilbert-Schmidt解,则密度矩阵$ρ(t)$的谱是Lie-Nambu动力学守恒的.这推广到任意可分的(正和不定度量)希尔伯特空间以前的结果是有效的有限维希尔伯特空间。
英文摘要:
The spectrum of a density matrix $ρ(t)$ is conserved by a Lie-Nambu dynamics if $ρ(t)$ is a self-adjoint and Hilbert-Schmidt solution of a nonlinear triple-bracket equation. This generalizes to arbitrary separable (positive- and indefinite-metric) Hilbert spaces the previous result which was valid for finite-dimensional Hilbert spaces.
