非平凡热库中的量子光学与量子模拟

与光场耦合的(人工)原子系统展示了很多丰富多彩的量子光学现象，例如，超辐射、亚辐射、以及光子诱导的原子间长程相互作用、等等。近年来，基于快速发展的微纳加工技术，人们可以在实验中设计具有很多新奇属性的热库，例如，具有Dirac点的能带结构和具有某些拓扑特性的光子晶体。由于与这些具有特殊性质的热库耦合，原子将展示出与自由光场耦合的原子非常不同的全新的动力学行为。通过对系统动力学的研究，人们可以发现很多不同于传统量子光学体系的新奇物理现象，并提供一个量子模拟的全新平台来理解量子化学、凝聚态物理、和高能物理中的平衡态和远离平衡态的问题，同时探索它在量子计算和量子信息等前沿领域中的广泛应用。因此，对于非平凡热库系统的研究正在成为一个蓬勃发展的前沿研究领域。本项目将致力于研究与非平凡热库耦合的单个和多个(人工)原子的量子光学，并探索它在量子计算、量子测量、和量子模拟中的应用。

The coupling of quantum emitters to a common bath gives rise to intriguing quantum optical phenomena, like super-radiance or dipole-dipole interactions. In recent years, new experimental setups are appearing where non-conventional baths, with novel controllable dispersion relations, can be produced. In particular, artificial atoms can be trapped in the proximity of photonic crystals (the bath), and their properties can be engineered owing to the spectacular progress in nano-fabrication techniques. Dispersion relations with Dirac points and exotic topological features can be designed in photonic crystals, which will dramatically affect the behavior of the atoms. In this scenario, exotic phenomena, unique possibilities for quantum simulation of both coherent and dissipative dynamics, as well as advanced applications are expected to emerge..In this project, we will develop the theoretical approaches that are required in this new field, explore and characterize novel phenomena, and propose and analyze physical setups where those phenomena can be observed and applied in quantum information and simulation. The research will involve the development in quantum optics and quantum simulations, as well as the study on emitters coupled to photonic crystals.
