固体氦剪切模量的应力和温度相关滞后
Stress- and temperature-dependent hysteresis in shear modulus of solid helium
摘要：
固体~ 4 He的剪切模量在200 mK以下出现异常的增大，其特征与扭振子实验中的周期减小现象有着显著的相似性。系统地研究了低温下剪切模量随驱动应变和温度的变化规律。滞后行为强烈依赖于驱动和冷却历史，这可以与热辅助Granato-Lucke位错理论。剪切模量的相图的基础上，新兴的滞回性能。
英文摘要：
The shear modulus of solid 4He below 200 mK exhibits an unusual increase, the characteristics of which show remarkable similarities to those of the period reduction in torsional oscillator experiments. We systematically studied the drive strain and temperature dependence of the shear modulus at low temperatures. The hysteretic behavior depends strongly on the drive and cooling history, which can be associated with the thermally assisted Granato-Lucke dislocation theory. The phase diagram of the shear modulus is constructed on the basis of the emerging hysteretic behavior.
