TL;DR: Results are consistent with theory, including a peak conductance that is proportional to tunnel coupling, saturates at 2e^{2}/h, decreases as expected with field-dependent gap, and collapses onto a simple scaling function in the dimensionless ratio of temperature and tunnel coupling.

TL;DR: Concomitant measurement of phase-dependent critical current and Andreev bound state spectrum in a highly transmissive InAs Josephson junction embedded in a dc superconducting quantum interference device (SQUID) shows excellent agreement with the one extracted from the SQUID critical current.

TL;DR: In this article, the authors report on a giant negative magnetoresistance in very high mobility GaAs/AlGaAs heterostructures and quantum wells and find that the effect is destroyed not only by increasing temperature but also by modest in-plane magnetic fields.

TL;DR: It is found that the oscillation amplitude decays exponentially with increasing temperature, as exp(-alphaT;{2}), where alpha scales with the inverse magnetic field, indicating that the temperature dependence originates primarily from the modification of the single particle lifetime.

TL;DR: In this paper, the microwave photoresistivity effect in a high-mobility two-dimensional electron system subject to a weak magnetic field and low temperature was observed, and the effect manifested itself as a giant microwave-induced resistivity peak which appeared only near the second harmonic of the cyclotron resonance and only at sufficiently high microwave frequencies.
