Finite-momentum Cooper pairing in proximitized altermagnets [PDF]
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]
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
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]
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 ...

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