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.

在2017财年，我是9篇已发表科学文章的合著者，其中一些发表在备受推崇的期刊上，如Physical Review X，Nature Communications和Physical Review Letters（PRL）。另外提交了3篇文章（其中一篇已在PRL上发表），还有几篇文章正在撰写中，包括关于光与物质之间超强耦合的大型综述。我曾在国际会议、研讨会和研讨会上发表过7次演讲和2次海报演讲。我的文章包括几篇关于超强光-物质耦合的文章。我们与Salvatore Savasta教授的团队一起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，以及在比以前认为的更低的机械频率下观察动态Casimir效应，并为光子探测和虚拟激发引入了新的微妙之处。这一点已被广泛引用。我还研究了巨原子的物理学，即，原子与光子在多个点耦合，这些点相隔很远（几个波长）。我为两个实验提供了理论支持：第一次演示了超导量子比特和表面声波谐振器之间的耦合，以及在驱动超导量子比特中没有粒子数反转的放大演示。
