We predict the existence of a thermal bistability in many-body systems out of thermal equilibrium which exchange heat by thermal radiation using insulator-metal transition materials. We propose a writing-reading procedure and demonstrate the possibility to exploit the thermal bistability to make a volatile thermal memory. We show that this thermal memory can be used to store heat and thermal information (via an encoding temperature) for arbitrary long times. The radiative thermal bistability could find broad applications in the domains of thermal management, information processing, and energy storage.
我们预测，在非热平衡的多体系统中存在热双稳性，该系统使用绝缘体-金属转变材料通过热辐射来交换热量。我们提出了一种写入-读取程序，并证明了利用热双稳性制造挥发性热存储器的可能性。我们表明，这种热存储器可用于长时间存储热量和热信息（通过编码温度）。辐射热双稳性可在热管理、信息处理和能量存储领域找到广泛应用。
