Adiabatic self-vibrations of a movable Cooper-pair box generated by inelastic Andreev tunneling
Sunghun Park, Anton V. Parafilo, Leonid Y. Gorelik +1
Self-sustained oscillators produce stable periodic motion robust to dissipation. Such motion is usually achieved by work fed back into the oscillator, but its performance is often…
Heat Coulomb blockade in a double-island metal-semiconductor device
A. V. Parafilo
We study the thermal transport properties of a mesoscopic device comprising two metallic islands embedded in a two-dimensional electron gas in the integer quantum Hall regime. It i…
Ratchet Hall Effect in Fluctuating Superconductors
A. V. Parafilo, V. M. Kovalev, I. G. Savenko
We propose a superconducting ratchet-induced Hall effect (RHE), characterized by the emergence of a unidirectional, rectified flux of fluctuating Cooper pairs in a two-dimensional…
Vertex corrections to nonlinear photoinduced currents in 2D superconductors
A. V. Parafilo, V. M. Kovalev, I. G. Savenko
The emergence of a rectified steady-state supercurrent as a response to the photoexcited current of the quasiparticles constitutes the concept of a superconducting photodiode. This…
Manifestation of Luttinger liquid effects in a hybrid metal-semiconductor double-quantum dot device
A. V. Parafilo
We theoretically study the transport properties of a hybrid nanodevice comprised of two large metallic islands incorporated in a two-dimensional electron gas. The high-tunability o…
Proposal for Superconducting Photodiode
A. V. Parafilo, Meng Sun, K. Sonowal +2
We propose a concept of a superconducting photodiode - a device that transforms the energy and `spin' of an external electromagnetic field into the rectified steady-state supercurr…
