New regimes of quantum optics in giant artificial atoms and hybrid systems

在2017财年，我与他人共同发表了9篇科学论文，其中一些发表在《物理评论X》、《自然通讯》和《物理评论快报》（PRL）等知名期刊上。另外提交了3篇文章（其中1篇已在PRL上发表），还有几篇文章正在撰写中，其中包括一篇关于光与物质之间超强耦合的大型综述。我在国际会议、讲习班和研讨会上做过7次演讲和2次海报展示。详情见附件列表。我的文章中有几篇是关于超强光-物质耦合的。与Salvatore Savasta教授的团队一起，我们展示了这种机制如何允许非线性光学的类似物，原子之间的多体相互作用，以及在比以前想象的更低的机械频率下观察动态卡西米尔效应，并为光子探测和虚拟激发引入了新的微妙之处。我用超导量子电路完成了有史以来最全面的量子光学综述；这句话被大量引用。我还研究了巨原子的物理学，即原子在相隔很远（几个波长）的多个点上与光子耦合。我为两个实验提供了理论支持：第一个超导量子比特和表面声波谐振器之间耦合的演示，以及在驱动超导量子比特中无种群反转的放大演示。

In FY2017, I was a co-author of 9 published scientific articles, some of which where published in highly regarded journals like Physical Review X, Nature Communications, and Physical Review Letters (PRL). Another 3 articles were submitted (1 of them has since been published in PRL) and several more articles are in the works, including a large review on ultrastrong coupling between light and matter. I have given 7 talks and 2 poster presentation at international conferences, workshops, and seminars. See attached list for details.My articles include several on the topic of ultrastrong light-matter coupling. Together with the group of professor Salvatore Savasta, we have shown how this regime allows analogs of nonlinear optics, many-body interactions among atoms, and observation of the dynamical Casimir effect at lower mechanical frequencies than previously thought, and introduces new subtleties for photon detection and virtual excitations.I completed the most comprehensive review ever of quantum optics with superconducting quantum circuits; this has become highly cited. I also studied the physics of giant atoms, i.e., atoms coupled to photons at multiple points separated by a large distance (several wavelengths). I provided theory support for two experiments: the first ever demonstration of coupling between a superconducting qubit and a resonator for surface acoustic waves and a demonstration of amplification without population inversion in a driven superconducting qubit.
