Metastability-assisted fatigue behavior in a friction stir processed dual-phase high entropy alloy (open access)

Metastability-assisted fatigue behavior in a friction stir processed dual-phase high entropy alloy

This article explores metastability-based high entropy alloy design which can open a new strategic path for designing high strength materials. However, high strength is always coupled with poor damage tolerance under cyclic loading conditions (fatigue). To overcome this drawback, the articles presents grain-refined Fe42Mn28Cr15Co10Si5 exhibiting significantly high fatigue strength as compared with leading transformation induced plasticity steels upon friction stir processing.

Probing Noise in Flux Qubits via Macroscopic Resonant Tunneling (open access)

Probing Noise in Flux Qubits via Macroscopic Resonant Tunneling

Article on the characterization of noise in a flux qubit using macroscopic resonant tunneling between the two lowest lying states of a bistable rf SQUID. Analysis of these results indicates that the dominant source of low energy flux noise in this device is a quantum mechanical environment in thermal equilibrium.

Geometrical dependence of the low-frequency noise in superconducting flux qubits

Article reporting on a study of a series of 85 devices of vary design using a general method for directly measuring the low-frequency flux noise (below 10 Hz) in compound Josephson-junction superconducting flux qubits. The results support the hypothesis that local impurities in the vicinity of the qubit wiring are a key source of low-frequency flux noise in superconducting devices.
