特征不确定关系

Characteristic uncertainty relations

D. A. Trifonov, S. G. Donev

摘要:

建立了n个可观测量的新的不确定关系。这些关系式采用r阶特征系数之间不等式的不变形式,r = 1,2,.,n的不确定性矩阵和可观测量的均值矩阵。结果表明,SU(1,1)和SU(2)的三个生成元的二阶和三阶特征不等式在相应的具有最大对称性的群相关相干态中最小化.

英文摘要:

New uncertainty relations for n observables are established. The relations take the invariant form of inequalities between the characteristic coefficients of order r, r = 1,2,...,n, of the uncertainty matrix and the matrix of mean commutators of the observables. It is shown that the second and the third order characteristic inequalities for the three generators of SU(1,1) and SU(2) are minimized in the corresponding group-related coherent states with maximal symmetry.
