Major in Physics Education 本人的目前研究聚焦在人工智能在量子计算和光与物质相互作用调控、量子光与物质相互相互作用领域，已经积累了一定的研究基础，取得了一系列的研究成果。发展了新的点群变换理论、空间量子通道理论和非均匀耗散结构中量子格林函数理论，利用数值计算，可以模拟分析表面等离激元局域和传播特性，并计算结构中受限光场与量子辐射系统的耦合强度、偶极－偶极相互作用、能级移动、演化谱、辐射谱和Fock态光子散射谱等特性。

具体工作介绍：10年前，国际同行在物理学评论快报上尝试用短时数据法结合FDTD 计算二维光子晶体中的局域态密度，但错误的短时数据法给出了错误的结果。在三维光子晶体中跃迁偶极矩的固定取向极大地降低了对称性，使方向性局域态密度的计算变得更加困难。2009 年，国际同行在物理学评论A、美国光学学会杂志（JOSAB）提出利用反演对称性简化计算光子晶体中光子取向局域态密度，但仍然是极端耗时的。我们提出一个新的点群变换理论并结合插值方法，比国际同行的方法快1000 倍，且使计算空间寿命分布成为可能[Phy. Rev. A, 85, 015802 (2012); Opt. Express 19, 11623 (2011); Journal of the Physical Society of Japan,81:114402(2012); Journal of the Physical Society of Japan 82(4):044402(2013)]等。

提出一种灵活且快速的从头计算方法能够模拟平板光子晶体结构中的投影局域态密度，解决了计算局域态密度的的重大挑战。基于光子的投影局域态密度,进一步发展了局域耦合理论, 可以同时处理任意纳米结构中量子比特与光子的弱耦合和强耦合相互作用。基于这种方法，我们很好地解释了光子晶体平板的实验结果，更重要的是，基于局域耦合强度，我们首次在投影局域态密度和腔量子电动力学之间建立了联系，用于快速求解品质因子、g因子和真空Rabi劈裂。该工作丰富了纳米结构中光子与量子比特相互作用的研究，为进一步研究纳米尺度上的光子与量子比特的相互作用提供了重要的理论指导和计算工具。具体内容参考论文[Phys. Rev. B 87, 195138 (2013)]；围绕在量子比特与光子晶体微腔强耦合系统的相关实验中观察到的在近共振条件下的三峰谱现象， 我们在一个实际的光子晶体平板L3腔结构中，通过对局域和传播的格林函数的准确数值模拟，研究了量子点与光场强耦合条件下的光辐射特性。在这样一个系统中，我们发现与探测点位置相关的传播函数具有洛仑兹线型，而且它的中心频率和线宽分别与投影局域态密度中的相应参数一致。我们进一步发现这个一致性是不依赖于放置于光子晶体微腔外的探测器的位置的，同时它也不受到横向泄漏的影响。我们的结果表明S.Hughes提出的假说不正确的。因此，当量子点和光子晶体微腔强耦合时，单纯的真空Rabi劈裂只能导致光辐射谱中出现双峰，而不能出现三峰, 相应的研究成果发表在[Optics Express 21, 23486（2013）]。

在三维空间中，实现光子与物质的强相互作用是非常困难的，在三维自由空间光场与物质的相互作用可以用散射截面表征，大的散射截面，表明光场容易和量子辐射子产生强相互作用。我们发展了Fock光子在自由空间中的量子输运理论和量子通道算法，该理论和算法可以解决任意数目和任意构型的多量子辐射系统与Fock态光子相互作用的输运问题。突破了Fock态光子在一维光波导中量子输运研究。在三维自由空间研究Fock态光子的输运，关键技术在于把三维问题转换为一维问题，从而利用一维波导量子电动力学理论，我们把三维连续空间看成非常多的通道（波导），任何一个波导中Fock光子用平面波展开，详细的研究结果发表在Optics Letters 41, 4166 (2016)期刊上.经典天线理论证明调控电磁场的辐射方向可以实现大的散射截面，该原理也适用于量子天线。通过设计量子辐射系统的空间构型，而实现多量子辐射系统的集体激发，从而产生超大方向性辐射。因此，系统的散射截面和多量子辐射系统的相干时间都可以在真空中得到长时间的增强，详细的研究结果参考Physical Review A 95, 013814 (2017)。 1.国家自然科学基金面上项目，11874438，表面等离激元与单量子系统室温强耦合作用量子调控研究，2019.01-2022.12，64万元，在研，参与排名第二。
