驱动谐振腔阵列中的排斥诱导光子超聚束

Repulsively induced photon super-bunching in driven resonator arrays

Thomas Grujic, Stephen R. Clark, Dieter Jaksch, Dimitris G. Angelakis

摘要:

我们分析了在特定光子多体模的选择性激发下,受驱动的非线性光子谐振腔阵列的非平衡行为。针对单位填充的基态,我们发现一个反直观的“超级聚束”的发射光子的统计,尽管相对较强的现场排斥相互作用。我们认为谐振器阵列与克尔非线性玻色哈伯德模型描述的,但也表明,类似的效果是观察到在不久的将来的实验耦合谐振器的两个级别的系统所描述的Jaynes Cummings哈伯德哈密顿。对于一对耦合谐振器形成光子分子的实验可访问的情况下,我们提供了一个分析解释的性质的效果。

英文摘要:

We analyze the non-equilibrium behaviour of driven nonlinear photonic resonator arrays under the selective excitation of specific photonic many-body modes. Targeting the unit-filled ground state, we find a counter-intuitive `super bunching' in the emitted photon statistics in spite of relatively strong onsite repulsive interaction. We consider resonator arrays with Kerr nonlinearities described by the Bose Hubbard model, but also show that an analogous effect is observable in near-future experiments coupling resonators to two-level systems as described by the Jaynes Cummings Hubbard Hamiltonian. For the experimentally accessible case of a pair of coupled resonators forming a photonic molecule, we provide an analytical explanation for the nature of the effect.
