Quantum thermalisation control

量子多体系统的平衡化、热化及其可控性是理论物理中长期悬而未决的问题。在过去的几年里，探索这些问题的第一次令人兴奋的实验已经成为可能。这种情况将是在量子热力学的背景下实现量子热化控制的起点。我们将探索平衡和热化与量子演化的统一性的关系，以建立对以下问题的全面回答：量子体系-浴络合物的子系统何时以及在什么精确意义上达到热平衡(目标a，b，c)？是否可以通过适当的控制(目标c)来防止或相反地加速这种平衡？远程相互作用是否与热化、延伸性和正常热流兼容(目标d)？

Equilibration and thermalisation of quantum many-body systems and their controllability are long-standing unresolved issues of theoretical physics. First exciting experiments exploring these issues have become available in the last few years. This state of affairs will be the starting point for achieving quantum thermalisation control in the context of quantum thermodynamics.We shall explore the rapport of equilibration and thermalisation with the unitarity of quantum evolution, so as to establish comprehensive answers to the questions: When and in what precise sense do subsystems of quantum system-bath complexes thermally equilibrate (Objectives a, b, c)? Can such equilibration be prevented or, conversely, sped up by suitable control (Objective c)? Are longe-range interactions compatible with thermalisation, extensivity and normal heat flow (Objective d)?
