熵弹簧的量子模型

A Quantum Model for Entropic Springs

Chiao-Hsuan Wang, Jacob M. Taylor

摘要:

出于理解热力学回复力和振荡的出现,我们开发了一个量子力学模型的自旋浴耦合到材料的弹性。我们表明,我们的模型再现了各种熵弹簧的行为,同时使调查的非平衡谐振器状态的量子域。我们发现我们的模型自然出现在无序的弹性介质,如玻璃,是一个额外的,预期的效果,在系统中的异常比热和1/f噪声在低温下,由于两个层次的系统波动。

英文摘要:

Motivated by understanding the emergence of thermodynamic restoring forces and oscillations, we develop a quantum-mechanical model of a bath of spins coupled to the elasticity of a material. We show our model reproduces the behavior of a variety of entropic springs while enabling investigation of non-equilibrium resonator states in the quantum domain. We find our model emerges naturally in disordered elastic media such as glasses, and is an additional, expected effect in systems with anomalous specific heat and 1/f noise at low temperatures due to two-level systems that fluctuate.
