Finite-momentum Cooper pairing in proximitized altermagnets [PDF]

open access: yesNature Communications, 2023
An altermagnet has highly anisotropic spin splitting but zero net magnetization. Here, S.-B. Zhang et al. theoretically study the behavior of s -wave superconductor/altermagnet hybrid structures, finding that Cooper pairs in the proximitized altermagnet ...

Momentum Contrast for Unsupervised Visual Representation Learning [PDF]

open access: yesComputer Vision and Pattern Recognition, 2019
We present Momentum Contrast (MoCo) for unsupervised visual representation learning. From a perspective on contrastive learning as dictionary look-up, we build a dynamic dictionary with a queue and a moving-averaged encoder. This enables building a large

The momentum of the solar energy transition

open access: yesNature Communications, 2023
Decarbonisation plans across the globe require zero-carbon energy sources to be widely deployed by 2050 or 2060. Solar energy is the most widely available energy resource on Earth, and its economic attractiveness is improving fast in a cycle of ...

Josephson diode effect from Cooper pair momentum in a topological semimetal [PDF]

open access: yesNature Physics, 2021
Cooper pairs in non-centrosymmetric superconductors can acquire finite centre-of-mass momentum in the presence of an external magnetic field. Recent theory predicts that such finite-momentum pairing can lead to an asymmetric critical current, where a ...

Spin-decoupled metasurface for simultaneous detection of spin and orbital angular momenta via momentum transformation

open access: yesLight: Science & Applications, 2021
With inherent orthogonality, both the spin angular momentum (SAM) and orbital angular momentum (OAM) of photons have been utilized to expand the dimensions of quantum information, optical communications, and information processing, wherein simultaneous ...

Coding and noncoding transcriptomes of NODULIN HOMEOBOX (NDX)-deficient Arabidopsis inflorescence

open access: yesScientific Data, 2023
Arabidopsis NODULIN HOMEOBOX (NDX) is a plant-specific transcriptional regulator whose role in small RNA biogenesis and heterochromatin homeostasis has recently been described. Here we extend our previous transcriptomic analysis to the flowering stage of
