Spin-filter tunneling detection of antiferromagnetic resonance with electrically-tunable damping

Posted by dbos Cornell

Kavli Affiliate: Daniel C. Ralph | First 5 Authors: Thow Min Jerald Cham, Daniel G. Chica, Xiaoxi Huang, Kenji Watanabe, Takashi Taniguchi | Summary: Antiferromagnetic spintronics offers the potential for higher-frequency operations and improved insensitivity to magnetic fields compared to ferromagnetic spintronics. However, previous electrical techniques to detect antiferromagnetic dynamics have utilized large, millimeter-scale bulk […]

Rich and diverse molecular gas environments of closely-separated dual quasars viewed by ALMA

Posted by dbos Tokyo

Kavli Affiliate: John D. Silverman | First 5 Authors: Shenli Tang, John D. Silverman, Zhaoxuan Liu, Manda Banerji, Tomoko Suzuki | Summary: We present a study of the molecular gas in five closely-spaced ($R_{perp}<20$ kpc) dual quasars ($L_{rm bol}gtrsim10^{44}~mathrm{erg~s}^{-1}$) at redshifts $0.4<z<0.8$ with the Atacama Large Millimeter/submillimeter Array. The dual quasar phase represents a distinctive […]

Heterogeneous integration of amorphous silicon carbide on thin film lithium niobate

Posted by dbos Delft

Kavli Affiliate: Simon Groblacher | First 5 Authors: Zizheng Li, Naresh Sharma, Bruno Lopez-Rodriguez, Roald van der Kolk, Thomas Scholte | Summary: In the past decade, lithium niobate (LiNbO3 or LN) photonics, thanks to its heat-free and fast electro-optical modulation, second-order non-linearities and low loss, has been extensively investigated. Despite numerous demonstrations of high-performance LN […]

Guidelines for Augmentation Selection in Contrastive Learning for Time Series Classification

Posted by dbos Berkeley

Kavli Affiliate: Xiang Zhang | First 5 Authors: Ziyu Liu, Azadeh Alavi, Minyi Li, Xiang Zhang, | Summary: Self-supervised contrastive learning has become a key technique in deep learning, particularly in time series analysis, due to its ability to learn meaningful representations without explicit supervision. Augmentation is a critical component in contrastive learning, where different […]
