Spinor Rydberg Polaritons

该项目研究旋量里德伯极化激元的两粒子和多粒子物理。里德伯极化激元是光子与里德伯原子的相干相互作用产生的准粒子，它导致强相互作用光子。利用数值波函数模拟和解析方法，我们将分析两粒子散射动力学以及旋量极化激元可能的束缚态。此外，我们还将研究低能区和一维空间中的多体物理。这里将使用DMRG（密度矩阵重整化群）等数值模拟技术以及玻色子化等场论方法。

The project investigates the two- and many-particle physics of spinor Rydberg polaritons. Rydberg-polaritons are quasiparticles that are generated in the coherent interaction of photons to Rydberg atoms which leads to strongly interacting photons. Making use of numerical wavefunction simulations and analytical approaches we will analyze the two-particle scattering dynamics as well as possible bound states of spinor polaritons. In addition we will stydy the many-body physics in the low-energy regime and in one spatial dimension. Here numerical simulation techniques such as DMRG (density-matrix renormalization group) as well as field-theoretical methods such as bosonization will be used.
