Strong mechanically-induced effects in DC current-biased suspended Josephson junctions [PDF]
, 2017 Superconductivity is a result of quantum coherence at macroscopic scales. Two superconductors separated by a metallic or insulating weak link exhibit the AC Josephson effect - the conversion of a DC voltage bias into an AC supercurrent.

Optimizing Energy-Harvesting Hybrid VLC/RF Networks With Random Receiver Orientation
IEEE AccessThis paper investigates an indoor hybrid visible light communication (VLC) and radio frequency (RF) scenario with two-hop downlink transmission. A light emitting diode (LED) transmits both data and energy via VLC to an energy-harvesting relay node, which

Anomalous transport in biased ac-driven Josephson junctions: Negative conductances [PDF]
, 2008 We investigate classical anomalous electrical transport in a driven, resistively and capacitively shunted Josephson junction device. Novel transport phenomena are identified in chaotic regimes when the junction is subjected to both, a time periodic (ac ...

A split-cavity design for the incorporation of a DC bias in a 3D microwave cavity
, 2017 We report on a technique for applying a DC bias in a 3D microwave cavity. We achieve this by isolating the two halves of the cavity with a dielectric and directly using them as DC electrodes.
