Strong coupling between light and matter means that photons can be absorbed and re-emitted many times before photons escape, or material excitations decay. Ultrastrong coupling means that the conversion between matter and light starts to approach the bare frequency of the cavity photons. In this regime, it is no longer appropriate to think of matter and light separately, but of the combined system, and the material properties can no longer be calculated in isolation. While such ideas have been discussed for some time in the context of THz or GHz frequency radiation, it has recently become accessible at optical frequencies using organic molecules in optical microcavities [1,2]. The aim of this project will be to explore a variety of strong and ultra-strong coupling phenomena in these systems, including coherent perfect absorption [3,4] (where impedance matching between mirror transmission and non-radiative losses is used to ensure maximum energy transfer to the matter-light system). In particular, building on recent work[5], we will explore how the vibrational sidebands present in molecular systems affect phenomena of strong and ultra-strong coupling. [1] S. Kéna-Cohen, S. a.

光和物质之间的强耦合意味着，在光子逃逸或物质激发衰变之前，光子可以被吸收和重新发射多次。超强耦合意味着物质和光之间的转换开始接近腔光子的裸频率。在这种情况下，不再适合把物质和光分开来考虑，而是把物质和光结合在一起，物质的性质也不能再孤立地计算出来。虽然这种想法在太赫兹或GHz频率辐射的背景下已经讨论了一段时间，但最近它已经可以在光学频率下使用光学微腔中的有机分子[1，2]。这个项目的目的将是探索这些系统中的各种强和超强耦合现象，包括相干完美吸收[3，4](其中使用镜面传输和非辐射损耗之间的阻抗匹配来确保最大限度地将能量转移到物质-光系统)。特别是，在最近工作[5]的基础上，我们将探索分子系统中存在的振动边带如何影响强耦合和超强耦合现象。[1]S.Kéna-Cohen，S.A.Maier和D.D.C.Bradley，Adv.Opt.马特。不适用(2013)。首页--期刊主要分类--期刊细介绍--期刊题录与文摘--期刊详细文摘内容化学。内部艾德恩格尔52,10533(2013年)。10.1002/anie.201301861[3]W.Chong，L.Ge，H.Noh，a D.Stone，and H.曹，Science 331,889(2011年).10.1038/nPhys3106[4]S.Zanotto，F.P.Mezzapesa，F.Bianco，G.Biasiol，L.Baldacci，M.S.Vitiello，L.Sorba，R.Colombeli，and A.Tredicucci，NAT.太棒了。10、(2014)。首页--期刊主要分类--期刊细介绍--期刊题录与文摘--期刊详细文摘内容让我们来吧。47009(2014年)。请列出任何商定的培训要求：培训通过苏格兰大学物理联盟(SUPA)研究生院提供。这包括40小时的必修技术课程和20小时的核心技能培训。到目前为止，商定的课程是：超量子系统-固体中的相互作用电子问题超量子系统-开放量子系统超AMPS-矩阵乘积状态和多体系统的张量网络方法
