李代数与广义热相干态

Lie Algebras and Generalized Thermal Coherent States

S. Floquet, M. A. S. Trindade, J. D. M. Vianna

摘要:

本文基于李群陪集空间,利用多模热场动力学方法,给出了广义热相干态的代数表达式。特别地,我们将我们的构造应用到$SU(2)$和$SU(1,1)$对称性上,得到了它们的热相干态和密度算符。计算了它们的热量子保真度和热维格纳函数。

英文摘要:

In this paper, we developed an algebraic formulation for the generalized thermal coherent states with a Thermofield Dynamics approach for multi-modes, based on coset space of Lie groups. In particular, we applied our construction on $SU(2)$ and $SU(1,1)$ symmetries and we obtain their thermal coherent states and density operator. We also calculate their thermal quantum Fidelity and thermal Wigner function.
