Non-unitary quantum electronics: Novel functions from the edge of the quantum world

Novel categories of electronic devices and quantum materials are obtained by pipelining the unitary evolution electron states as described Schroedinger's equation with non-unitary processes that interrupt coherent propagation electrons. These reside in fascinating transition regime between mechanics classical physics. The designed such a nonreciprocal state is achieved means broken inversion symmetry, for example induced at material interfaces. This interrupted individual inelastic scattering events caused defects coupled to an environment. Two-terminal devices, example, feature conductance linear response. Thus, they exemptions Onsager's reciprocal relation, challenge second law thermodynamics. Implementing device function into unit cells or meta-materials yields novel functionalities 2D 3D materials, interfaces, heterostructures.
