In FY2016, I have been a co-author of 6 submitted scientific articles. Several more articles are in the works, including a large review on quantum optics with superconducting circuits. I have given 11 talks and 1 poster presentation at international conferences, workshops, and seminars. See attached list for details.Among the 6 articles, 3 are theoretical studies of ultrastrong coupling between atoms and photons. In collaboration with several other researchers, we have shown that a wealth of new processes become possible in this regime, e.g., efficient analogues of nonlinear optics and many-body interactions among atoms. All these new processes are within reach for experiments in circuit quantum electrodynamics (QED).In one article, I studied the physics of a single atom coupled to photons at multiple points separated by a large distance. This new regime of quantum optics can be implemented with surface acoustic waves (SAWs). In another article, I provided theoretical support for an experimental group at Oxford who demonstrated, for the first time in the world, coupling between a resonator for such SAWs and a superconducting artificial atom. The last article I co-authored studied fundamental test of quantum mechanics with many atoms using Leggett-Garg inequalities.

在2016财年，我是6篇提交的科学文章的合著者。还有几篇文章正在撰写中，包括一篇关于超导电路量子光学的大型评论。我在国际会议、工作坊和研讨会上发表了11次演讲和1次海报展示。在这6篇文章中，有3篇是关于原子与光子之间超强耦合的理论研究。在与其他几位研究人员的合作中，我们已经证明，在这种制度下，许多新的过程成为可能，例如，非线性光学和原子间多体相互作用的有效模拟。所有这些新的过程都可以在电路量子电动力学（QED）实验中实现。在一篇文章中，我研究了单个原子与光子在相隔很远的多个点耦合的物理学。这种量子光学的新机制可以用表面声波（SAW）来实现。在另一篇文章中，我为牛津大学的一个实验组提供了理论支持，该实验组在世界上首次展示了这种SAW谐振器与超导人造原子之间的耦合。我与人合著的最后一篇文章研究了多原子量子力学的基本检验，使用Leggett-Garg不等式。
