Nonunitary Quantum Electronics

 

Propagation of an electron wave packet in a nanodevice consisting of an asymmetric quantum ring with two contacts. The ring is biased with a magnetic field. Link to research article "Decoherence Effects Break Reciprocity in Matter Transport"


Decoherence Effects Break Reciprocity in Matter Transport

Sketch illustrating the principle of the novel quantum materials. These materials contain noncentrosymmetric unit cells with embedded inelastic scattering centers, drawn as gold dots. These centers break the phase coherence of the electron wave packets. Link to research article "Non-unitary Quantum Materials"

Temporal development of the total entropy for a closed variant of our system, shown in the inset. The initial state (thermal equilibrium between all subsystems, including the waveguide) maximizes the entropy. The stable steady state for long times has a lower entropy.
