Abstract Memristors, a cornerstone for neuromorphic electronics, respond to the history of electrical stimuli by varying their electrical resistance across a continuum of states. Much effort has been recently devoted to developing an analogous respon

Extracting information from radio-frequency (RF) signals using artificial neural networks at low energy cost is a critical need for a wide range of applications from radars to health. These RF inputs are composed of multiple frequencies. Here, we sho

Abstract In a spintronic resonator a radio-frequency signal excites spin dynamics that can be detected by the spin-diode effect. Such resonators are generally based on ferromagnetic metals and their responses to spin torques. New and richer functiona

Metasurfaces are two-dimensional nanostructures that allow unprecedented control of light through engineering the amplitude, phase, and polarization across meta-atom resonators. Adding tunability to metasurface components would boost their potential

Arrays of superconducting quantum interference devices (SQUIDs) are highly sensitive magnetometers that can operate without a flux-locked loop, as opposed to single SQUID magnetometers. They have no source of ambiguity and benefit from a larger bandw

We compare the potential of SQUID arrays and Josephson junction arrays as magnetic field detectors in an open-loop configuration, accounting for such limitations as technological parameter fluctuations, current density distribution and self-field eff

Description
This work shows how itinerant electrons localize due to increased interactions across the Mott metal-insulator transition.
In solids, strong repulsion between electrons can inhibit their movement and result in a “Mott” metal

We studied the voltage-induced resistive switching (RS) in ferroelectric/metal (BiFeO3/Nb:SrTiO3) vertical devices. We found switching with RON and ROFF ratios of ΔR = 1-RON/ROFF = 0.82 at voltages starting at VSET, RESET = ±2 V. Upon increasing vo
