摘要翻译：
热化非平衡物质的一个特征是，尽管存在能量弛豫--平衡，多体系统激发方式的相记忆仍然存在。作为一个例子，我们分析了Bi($\γ$，p)光核反应中热质子产额的强前向峰。新的分析表明，高激发态重核中的位相弛豫可以达到8个数量级，甚至比能量弛豫还要长得多。我们认为热化的非平衡物质类似于量子多体系统中的高温超导态。我们简要地给出了这类超导态的多粒子密度涨落与时间相关函数的结果。在多体介观系统和纳米结构中，从实验上寻找热非平衡物质的表现应该是有意义的。

英文摘要：
A characteristic feature of thermalized non-equilibrated matter is that, in spite of energy relaxation--equilibration, a phase memory of the way the many-body system was excited remains. As an example, we analyze data on a strong forward peaking of thermal proton yield in the Bi($\gamma$,p) photonuclear reaction. New analysis shows that the phase relaxation in highly-excited heavy nuclei can be 8 orders of magnitude or even much longer than the energy relaxation. We argue that thermalized non-equilibrated matter resembles a high temperature superconducting state in quantum many-body systems. We briefly present results on the time-dependent correlation function of the many-particle density fluctuations for such a superconducting state. It should be of interest to experimentally search for manifestations of thermalized non-equilibrated matter in many-body mesoscopic systems and nanostructures.
