标题： Kinetic Spinodal Instabilities in the Mott Transition in V2O3: Evidence from Hysteresis Scaling and Dissipative Phase Ordering

摘要： 我们首次系统观察了在关联电子系统中急剧热力学转变附近，热滞回与温度扫描速率的标度关系。 我们表明，在二氧化钒（V2O3）中，过冷和过热的深度随着温度淬火速率而变化。 动态标度指数接近平均场理论预测的 2/3。 这些观察结果结合“淬火-保持”实验中纯粹耗散的连续有序现象，表明向与临界动力学相关的无势垒相序的偏离。 在热诱导急剧相变中观察到类似临界特征和标度，表明类旋节线不稳定性的存在不仅是平均场理论的人工产物，也可以存在于实际系统的转变动力学中，经受涨落的考验。 显示英文摘要

摘要： We present the first systematic observation of scaling of thermal hysteresis with the temperature scanning rate around an abrupt thermodynamic transition in correlated electron systems. We show that the depth of supercooling and superheating in vanadium sesquioxide (V2O3) shifts with the temperature quench rates. The dynamic scaling exponent is close to the mean field prediction of 2/3. These observations, combined with the purely dissipative continuous ordering seen in "quench-and-hold" experiments, indicate departures from classical nucleation theory toward a barrier-free phase ordering associated with critical dynamics. Observation of critical-like features and scaling in a thermally induced abrupt phase transition suggests that the presence of a spinodal-like instability is not just an artifact of the mean field theories but can also exist in the transformation kinetics of real systems, surviving fluctuations.
