Kavli Affiliate: Daniel C. Ralph | First 5 Authors: Xiaoxi Huang, Xianzhe Chen, Yuhang Li, John Mangeri, Hongrui Zhang | Summary: A collective excitation of the spin structure in a magnetic insulator can transmit spin-angular momentum with negligible dissipation. This quantum of a spin wave, introduced more than nine decades ago, has always been manipulated […]
Kavli Affiliate: Daniel C. Ralph | First 5 Authors: Thow Min Jerald Cham, Reiley J. Dorrian, Xiyue S. Zhang, Avalon H. Dismukes, Daniel G. Chica | Summary: Magnetic van der Waals heterostructures provide a unique platform to study magnetism and spintronics device concepts in the two-dimensional limit. Here, we report studies of exchange bias from […]

Kavli Affiliate: Alex Zettl | First 5 Authors: Hongyuan Li, Ziyu Xiang, Mit H. Naik, Woochang Kim, Zhenglu Li | Summary: Moir’e superlattices provide a highly tunable and versatile platform to explore novel quantum phases and exotic excited states ranging from correlated insulators1-17 to moir’e excitons7-10,18. Scanning tunneling microscopy has played a key role in […]
Kavli Affiliate: Feng Wang | First 5 Authors: Feng Wang, Chuan-Fu Yang | Summary: We consider the Sturm-Liouville operator on the lasso graph with a segment and a loop joined at one point, which has arbitrary length. The Ambarzumyan’s theorem for the operator is proved, which says that if the eigenvalues of the operator coincide […]
Kavli Affiliate: Joel E. Moore | First 5 Authors: Sijie Xu, Rabindranath Bag, Nicholas E. Sherman, Lalit Yadav, Alexander I. Kolesnikov | Summary: The emergence of a quantum spin liquid (QSL), a state of matter that can result when electron spins are highly correlated but do not become ordered, has been the subject of a […]

Kavli Affiliate: Alessandra Lanzara | First 5 Authors: Ping Ai, Luca Moreschini, Ryo Mori, Drew W. Latzke, Jonathan D. Denlinger | Summary: Molecular crystals are a flexible platform to induce novel electronic phases. Due to the weak forces between molecules, intermolecular distances can be varied over relatively larger ranges than interatomic distances in atomic crystals. […]

Kavli Affiliate: Xiang Zhang | First 5 Authors: Xiang Zhang, Yan Lu, Huan Yan, Jingyang Huang, Yusheng Ji | Summary: Because of the ambiguous and subjective property of the facial expression recognition (FER) task, the label noise is widely existing in the FER dataset. For this problem, in the training phase, current FER methods often […]
