论文摘要
绝热进化被认为是大多数热力学周期的理想情况，因为它允许实现最大效率。但是，鉴于执行转换所需的无限时间，没有产生功率输出。可以通过快捷方式到可绝化（STA）协议克服此类问题，该协议允许动态模仿其绝热对应物，但在有限的时间内。无过渡量子驾驶（TQD）是STA的一种形式。我们开发并研究了TQD对经过不断变化的磁场和具有时间依赖性相互作用强度的一般双Qubit Heisenberg模型的单量系统系统的影响。我们建立了跨动力学的作品与由手头的演变产生的熵产生的作品之间的定量关系，重点是工作介质的初始状态所起的作用。我们确定在TQD协议下极端绩效的国家。最后讨论了STA的热力学意义。
Adiabatic evolution is considered to be the ideal situation for most thermodynamic cycles, as it allows for the achievement of maximum efficiency. However, no power output is produced in light of the infinite amount of time required to perform a transformation. Such issue can be overcome through Shortcuts-To-Adiabaticity (STA) protocols, which allows a dynamics to mimic its adiabatic counterpart, but in a finite time. Transitionless quantum driving (TQD) is one form of STA. We develop and study the effects of TQD on a single-qubit system subjected to a changing magnetic field and a general two-qubit Heisenberg model with a time-dependent interaction strength. We establish a quantitative relation between the work produced across the dynamics and the entropy production resulting from the evolution at hand, focusing on the role played by the initial states of the work medium. We identify the states that extremize performance under the TQD protocol. The thermodynamic implications of STA are discussed in the end.
