一维热哈密顿量的谱理论

Spectral Theory of the Thermal Hamiltonian: 1D Case

Giuseppe De Nittis, Vicente Lenz

摘要:

1964年,J.M. Luttinger介绍了一个量子热输运模型。本文研究了与Luttinger模型相关的Hamilton算子的谱理论,特别是在一维情形。结果表明,(所谓的)热哈密顿量有一个单参数家庭的自伴扩展和频谱,时间传播群和格林函数显式计算。此外,卷积型势的散射进行了分析。最后,也完全解决了相关的经典问题,从而提供了经典和量子行为之间的比较。本文的目的是第一次在建设一个完整的理论热哈密顿量的贡献。

英文摘要:

In 1964 J. M. Luttinger introduced a model for the quantum thermal transport. In this paper we study the spectral theory of the Hamiltonian operator associated to the Luttinger's model, with a special focus at the one-dimensional case. It is shown that the (so called) thermal Hamiltonian has a one-parameter family of self-adjoint extensions and the spectrum, the time-propagator group and the Green function are explicitly computed. Moreover, the scattering by convolution-type potentials is analyzed. Finally, also the associated classical problem is completely solved, thus providing a comparison between classical and quantum behavior. This article aims to be a first contribution in the construction of a complete theory for the thermal Hamiltonian.
