论文摘要
从宇宙学到电磁学的所有物理学分支中,都出现了非重生的概念,从本质上讲与向后的概念不同。有趣的是,互惠的分解通常与非凡现象有关,当Lorentz互惠破坏时,可以很容易地将其大写在(例如)非平凡的电磁设备的设计中。但是,为了在下一代量子技术中剥削非逆局性效应,需要基本的量子光学理论。在这里,我们提出了一个多功能模型,描述了一对驱动驱动的量子谐振器,其中相干和不相干耦合之间的相对相差会诱导不对称性。各种耗散景观之间的相互作用 - 涵盖了内在损失和耗散耦合 - 以及相干相互作用会带来一些显着的后果,包括高度方向(甚至是单向)能量运输。我们的工作使观察耗散诱导的量子方向性的诱人前景(如光子或腔镁(自旋波))可能有助于设计非常规的纳米镜头装置。
The notion of nonreciprocity, in essence when going forwards is different from going backwards, emerges in all branches of physics from cosmology to electromagnetism. Intriguingly, the breakdown of reciprocity is typically associated with extraordinary phenomena, which may be readily capitalized on in the design of (for example) nontrivial electromagnetic devices when Lorentz reciprocity is broken. However, in order to enable the exploitation of nonreciprocal-like effects in the next generation of quantum technologies, basic quantum optical theories are required. Here we present a versatile model describing a pair of driven-dissipative quantum resonators, where the relative phase difference between the coherent and incoherent couplings induces an asymmetry. The interplay between the diverse dissipative landscape - which encompasses both intrinsic losses and dissipative couplings - and the coherent interactions leads to some remarkable consequences including highly directional (or even one-way) energy transport. Our work proffers the tantalizing prospect of observing dissipation-induced quantum directionality in areas like photonics or cavity magnonics (spin waves), which may aid the design of unconventional nanoscopic devices.
