Topological superconductivity (TSC) is predicted to exist in nanowires with strong spin-orbit coupling (SOC) when they are in proximity to superconductors, with a key signature being zero-energy states in conductance measurements. Here, using weak-SO

Simultaneous breaking of inversion and time-reversal symmetries in a conductor yields a non-reciprocal electronic transport1,2,3, known as the diode or rectification effect, that is, low (ideally zero) conductance in one direction and high (ideally i

The control of light-matter interaction at the most elementary level has become an important resource for quantum technologies. Implementing such interfaces in the THz range remains an outstanding problem. Here, we couple a single electron trapped in

Publikováno v: CLARA. 9

The mosaic of the six female musicians from Mariamin in Syria depicts in exquisite detail a late antique musical performance. The present study focuses on the cymbal tongs player and the finger cymbals player from this mosaic, who have raised little

We use a quantum path integral approach to describe the behavior of a microwave cavity coupled to a dissipative mesoscopic circuit. We integrate out the mesoscopic electronic degrees of freedom to obtain a cavity effective action at fourth order in t
