In their newest research, Downing and Zueco provide a quantum theory of non-reciprocal transport around a triangular cluster of strongly connecting quantum objects. Influenced by the physics of quantum rings, they reveal that by crafting a synthetic magnetic field one may tune the direction of the energy flow around the cluster. The theory accounts for strong particle interactions, such that directionality appears at a swathe of energies, and considers the pernicious effect of dissipation for the formation of non-reciprocal quantum currents.
The research may be beneficial in the development of quantum devices requiring efficient, directional transport, as well for more studies of highly communicating quantum stages, artificial magnetic fields, and quantum simulators.
Charles Downing from the University of Exeter discusses: “Our computations provide insight into how one may initiate directional transport in closed nanoscopic lattices of atoms and photons with strong interactions, which may result in the development of unique devices of a highly directional character.”

Physicists from Exeter and Zaragoza have produced a theory describing how non-reciprocity can be induced at the quantum level, paving the method for non-reciprocal transport in the next generation of nanotechnology
A set of theoretical physicists, from the University of Exeter (United Kingdom) and the University of Zaragoza (Spain), have actually established a quantum theory describing how to craft non-reciprocal flows of quantum light and matter. The research may be essential for the development of quantum innovations that need the directional transfer of energy and details at little scales.
Reciprocity, going the same way backward as forward, is an ubiquitous idea in physics. A well-known example may be found in Newtons Law: for each action there is a equivalent and opposite response. The breakdown of such an effective idea as reciprocity in any location of physics, from mechanics to optics to electromagnetism, is generally connected with surprises that can be exploited for technological application. For example, a nonreciprocal electric diode allows present to pass in forward however not backwards and forms a foundation of the microelectronics industry.
