摘要

具有负热容量的热力学系统具有奇特的行为特征，但在从大尺度到纳米尺度的多个系统中都有报道。我们的研究表明，负热容量可能出现在低维/纳米量子振荡器中，这是因为在掺杂不足的铜氧化物和量子阱中观察到了强电子相关性，而在包括介观系统在内的多个量子系统中都出现了负态密度。

Negative heat capacity in low-dimensional systems using non-local kernel approach

Thermodynamical systems having negative heat capacity are characterised by peculiar behaviours, yet they have been reported in several systems ranging from large to nanoscales. We show that negative heat capacity may arise in low-dimensional/nano quantum oscillators due to strong electron correlations observed in underdoped cuprates and quantum wells with negative density of states which emerge in several quantum systems including mesoscopic systems.
