Nonunitary Quantum Devices – Electronics at the Edge of the Quantum World –

25.11.2021 13:15 – 14:00

In the fascinating transition regime between quantum mechanics and classical physics, the dynamics of electrons is open to the combined degrees of freedom of both worlds.
In the presentation, I will show that this transition regime accommodates a whole new category of electronic devices. These operate by using individual, inelastic scattering events to interrupt the coherent propagation of electrons. By exceeding the constraints of classical physics and of quantum mechanics as given by Schrödinger’s equation, they offer stunning functionalities that cannot be achieved by any other means. These devices provide an exemption to Onsager’s reciprocity relation and challenge the second law of thermodynamics.
