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: Zhiting Tian | First 5 Authors: Abhijit Biswas, Gustavo A. Alvarez, Tao Li, Joyce Christiansen-Salameh, Eugene Jeong | Summary: Heterostructures based on ultrawide-bandgap (UWBG) semiconductors (bandgap >4.0 eV), boron nitride (BN) and diamond are important for next-generation high-power electronics. However, in-situ hetero-epitaxy of BN/diamond or vice-versa remains extremely challenging, due to their non-trivial […]

Kavli Affiliate: Grace Xing | First 5 Authors: Len van Deurzen, Jashan Singhal, Jimy Encomendero, Naomi Pieczulewski, Celesta Chang | Summary: Using low-temperature cathodoluminescence spectroscopy, we study the properties of N- and Al-polar AlN layers grown by molecular beam epitaxy on bulk AlN{0001}. Compared to the bulk AlN substrate, layers of both polarities feature a […]

Kavli Affiliate: Dan Luo | First 5 Authors: Dan Luo, Lixin Zou, Qingyao Ai, Zhiyu Chen, Chenliang Li | Summary: The goal of unbiased learning to rank (ULTR) is to leverage implicit user feedback for optimizing learning-to-rank systems. Among existing solutions, automatic ULTR algorithms that jointly learn user bias models (i.e., propensity models) with unbiased […]
Kavli Affiliate: David A. Muller | First 5 Authors: Zeming Sun, Zhaslan Baraissov, Catherine A. Dukes, Darrah K. Dare, Thomas Oseroff | Summary: Surface structures on radio-frequency (RF) superconductors are crucially important in determining their interaction with the RF field. Here we investigate the surface compositions, structural profiles, and valence distributions of oxides, carbides, and […]
Kavli Affiliate: Dan Luo | First 5 Authors: Yuexi Zhang, Dan Luo, Balaji Sundareshan, Octavia Camps, Mario Sznaier | Summary: Cross view action recognition (CVAR) seeks to recognize a human action when observed from a previously unseen viewpoint. This is a challenging problem since the appearance of an action changes significantly with the viewpoint. Applications […]

Kavli Affiliate: Jie Shan | First 5 Authors: Yihang Zeng, Zhengchao Xia, Kaifei Kang, Jiacheng Zhu, Patrick Knüppel | Summary: Chern insulators, which are the lattice analogs of the quantum Hall states, can potentially manifest high-temperature topological orders at zero magnetic field to enable next-generation topological quantum devices. To date, integer Chern insulators have been […]
