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篇发表的科学文章的合着者，其中一些文章发表在众多备受推崇的期刊上，例如物理评论X，自然通讯和物理评论信（PRL）。另有3篇文章提交了（其中1篇文章已在PRL中发表），还有更多文章正在进行中，包括对光和物质之间的超局势耦合进行了大量审查。我在国际会议，研讨会和研讨会上进行了7次演讲和2张海报演讲。有关详细信息，请参见附件列表。与Salvatore Savasta教授一起，我们展示了该制度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较低的机械频率下的动态Casimir效应的观察，并与以前认为的动态效应相比，并引入了最全面的循环。这已经被引用了。我还研究了巨大原子的物理学，即在多个点上以较大距离（几个波长）隔开的光子耦合的原子。我为两个实验提供了理论支持：超导量子与表面声波的谐振器之间耦合的第一个证明，以及在驱动的超导零件中没有种群反转的放大的演示。
