论文摘要
我们展示了两个示例，其中可以通过调节KERR或高阶非线性来实现动态casimir效应。在第一种情况下，通过偶极相互作用将腔场耦合到任意数量的Qubits或谐波振荡器。在第二种情况下，非线性的调节伴随着腔频率的异位调节。我们介绍了该现象的分析描述，并用数字模拟补充了它，表明可以通过真空创建光子，而所得的超硫代硫磺光子统计量与挤压真空状态有很大不同。
We show two examples in which the dynamical Casimir effect can be achieved by modulating the Kerr or higher order nonlinearities. In the first case the cavity field is coupled to an arbitrary number of qubits or an harmonic oscillator via the dipole interaction. In the second case, the modulation of the nonlinearities is accompanied by the off-resonance modulation of the cavity frequency. We present the analytic description of the phenomenon and supplement it with numeric simulations, demonstrating that photons can be created from vacuum and the resulting hyper-Poissonian photon statistics is very different from the squeezed vacuum state.
