Kavli Affiliate: Gregory D. Fuchs | First 5 Authors: Jialun Luo, Yifei Geng, Farhan Rana, Gregory D. Fuchs, | Summary: Optically detected magnetic resonance (ODMR) is an efficient mechanism to readout the spin of solid-state color centers at room temperature, thus enabling spin-based quantum sensors of magnetic field, electric field, and temperature with high sensitivity […]
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: Debanjan Chowdhury | First 5 Authors: Thomas G. Kiely, Debanjan Chowdhury, , , | Summary: Electrons can organize themselves into charge-ordered states to minimize the effects of long-ranged Coulomb interactions. In the presence of a lattice, commensurability constraints lead to the emergence of incompressible Wigner-Mott insulators at various rational electron fillings, $nu~=p/q$. The […]
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 […]
