It is widely assumed that photons cannot be manipulated using electric or magnetic fields. Even though hybridization of photons with electronic polarization to form exciton-polaritons has paved the way to a number of ground-breaking experiments in semiconductor microcavities, the neutral bosonic nature of these quasiparticles has severely limited their response to external gauge fields. Here, we demonstrate polariton acceleration by external electric and magnetic fields in the presence of nonperturbative coupling between polaritons and itinerant electrons, leading to formation of new quasiparticles termed polaron-polaritons. We identify the generation of electron density gradients by the applied fields to be primarily responsible for inducing a gradient in polariton energy, which in turn leads to acceleration along a direction determined by the applied fields. Remarkably, we also observe that different polarization components of the polaritons can be accelerated in opposite directions when the electrons are in $\nu =1$ integer quantum Hall state.

通过外部电场和磁场加速极化子

人们普遍认为光子不能使用电场或磁场来操纵。尽管将光子与电子极化杂交形成激子-极化子已为半导体微腔中的许多突破性实验铺平了道路，但这些准粒子的中性玻色子性质严重限制了它们对外部规范场的响应。在这里，我们证明了在极化子和流动电子之间存在非微扰耦合的情况下，外部电场和磁场对极化子的加速作用，从而导致形成称为极化子-极化子的新准粒子。我们通过施加的电场确定了电子密度梯度的产生，主要是引起极化子能量的梯度，进而导致沿由施加磁场确定的方向加速。值得注意的是，我们还观察到，当电子在其中时，极化子的不同极化分量可以沿相反方向加速$\nu =\mathrm{1个}$ 整数量子霍尔状态。
