通过利用量子现象，量子器件有可能超越经典器件。在这里，我们研究使用波函数对称性作为资源，以提高量子奥托引擎的性能。先前的工作已经表明，玻色子工作介质可以产生比费米子介质更好的性能。我们扩大这项工作，将一个奇异的相互作用，使有效的对称性之间的玻色子和费米子限制进行调整。在这个框架中，粒子可以被看作是任意子，服从Halfman的广义不相容统计。使用“统计任意子”的框架解析求解动力学，我们探讨了粒子间相互作用和波函数对称性对发动机性能的影响。
By harnessing quantum phenomena, quantum devices have the potential to outperform their classical counterparts. Here, we examine using wave function symmetry as a resource to enhance the performance of a quantum Otto engine. Previous work has shown that a bosonic working medium can yield better performance than a fermionic medium. We expand upon this work by incorporating a singular interaction that allows the effective symmetry to be tuned between the bosonic and fermionic limits. In this framework, the particles can be treated as anyons subject to Haldane's generalized exclusion statistics. Solving the dynamics analytically using the framework of "statistical anyons", we explore the interplay between interparticle interactions and wave function symmetry on engine performance.
