- Title: Directionality between driven-dissipative resonators
- Authors: C. A. Downing and T. J. Sturges
- Abstract summary: We present a 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.
Our work proffers the tantalizing prospect of observing dissipation-induced quantum directionality in areas like photonics or cavity magnonics.

- Abstract: 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.

We show that the asymmetry may emphincrease as a result of a emphdecrease of coherence inside a degenerate subspace.

We present nanoscale devices in which decoherence, modeled by random quantum jumps, produces fundamentally novel phenomena by interrupting the unitary dynamics of electron wave packets.
In these devices, the inelastic interaction of itinerant electrons with impurities acting as electron trapping centers leads to a novel steady state characterized by partial charge separation between the two leads.
The interface between the quantum and the classical worlds therefore provides a novel transport regime of value for the realization of a new category of mesoscopic electronic devices.
