Self-ordering (and superradiance) in cavity quantum-electrodynamics

Speaker’s Brief Introduction： Farokh Mivehvar 博士今朝担当奥天时因斯布鲁克年夜学 （University of Innsbruck）实践物理研究所的 FWF 自力研究员（FWF Stand-alone Fellow）。Farokh Mivehvar 博士本科结业于伊朗年夜没有里士年夜学（University of Tabriz），随后正在加拿年夜卡尔加里年夜学（University of Calgary）实现了研究生学业。今后，他前去奥天时因斯布鲁克年夜学从事博士后研究，首要致力于腔量子电能源学（Cavity QED）范畴。Mivehvar 博士的研究乐趣普遍，横跨凝聚态物理、量子气体、量子光学和量子紧密丈量等多个前沿范畴。他正在量子物资密度波调控，量子光诱导涌现准晶对称性 （Emergent Quasicrystalline Sy妹妹etry）和重访“超辐射”（Superradiance）实践等方面取患了重要结果。

Abstract: “Self-ordering” — the spontaneous emergence of order out of disorder and chaos under some critical conditions — is a ubiquitous phenomenon not only in physics, but also in chemistry, biology, social sciences, and many other fields. The most well-known example in physics is the crystallization process, while the other co妹妹only known general examples include the collective bird flocking and fish schooling. In this talk, I will discuss the basic physics of self-ordering in open atom-cavity quantum systems [1]. In these systems, self-ordering is normally accompanied by the so-called “superradiance”, which I will also explain. In the end, I will present some of our new predictions for quantized vortex self-ordering in atom-cavity systems, which leads to the so-called “rotational superradiance”.
