Kavli Affiliate: Darrell G. Schlom | First 5 Authors: Anita Verma, Denis Golež, Oleg Yu. Gorobtsov, Kelson Kaj, Ryan Russell | Summary: Technology moves towards ever faster switching between different electronic and magnetic states of matter. Manipulating properties at terahertz rates requires accessing the intrinsic timescales of electrons (femtoseconds) and associated phonons (10s of femtoseconds […]

Kavli Affiliate: J. C. Seamus Davis | First 5 Authors: Harris Pirie, Eric Mascot, Christian E. Matt, Yu Liu, Pengcheng Chen | Summary: A Kondo lattice is often electrically insulating at low temperatures. However, several recent experiments have detected signatures of bulk metallicity within this Kondo insulating phase. Here we visualize the real-space charge landscape […]

Kavli Affiliate: Jie Shan | First 5 Authors: Zui Tao, Bowen Shen, Wenjin Zhao, Nai Chao Hu, Tingxin Li | Summary: The spin Hall effect (SHE), in which electrical current generates transverse spin current, plays an important role in spintronics for the generation and manipulation of spin-polarized electrons. The phenomenon originates from spin-orbit coupling. In […]

Kavli Affiliate: Grace Xing | First 5 Authors: Jimy Encomendero, Vladimir Protasenko, Debdeep Jena, Huili Grace Xing, | Summary: Resonant tunneling transport in polar heterostructures is intimately connected to the polarization fields emerging from the geometric Berry-phase. In these structures, quantum confinement results not only in a discrete electronic spectrum, but also in built-in polarization […]

Kavli Affiliate: Farhan Rana | First 5 Authors: Jimy Encomendero, Vladimir Protasenko, Farhan Rana, Debdeep Jena, Huili Grace Xing | Summary: The recent demonstration of resonant tunneling transport in nitride semiconductors has led to an invigorated effort to harness this quantum transport regime for practical applications. In polar semiconductors, however, the interplay between fixed polarization […]

Kavli Affiliate: David Muller | First 5 Authors: David Müller, Emerson Melo, Ruben Schlotter, , | Summary: This paper introduces the distributionally robust random utility model (DRO-RUM), which allows the preference shock (unobserved heterogeneity) distribution to be misspecified or unknown. We make three contributions using tools from the literature on robust optimization. First, by exploiting […]

Kavli Affiliate: Nicholas L. Abbott | First 5 Authors: Apoorva Jain, Soumyamouli Pal, Nicholas L. Abbott, Rong Yang, | Summary: The ability to synthesize shape-controlled polymer particles will benefit a wide range of applications including targeted drug delivery and metamaterials with reconfigurable structures, but existing synthesis approaches are commonly multistep and limited to a narrow […]

Kavli Affiliate: Gregory D. Fuchs | First 5 Authors: Yanyou Xie, Hil Fung Harry Cheung, Gregory D. Fuchs, , | Summary: In this work, we develop a nanoscale magnetic field sensor based on a spin-Hall nano-oscillator (SHNO) device. We fabricate constriction-based SHNO devices using Ni$_{81}$Fe$_{19}$/Au$_{0.25}$Pt$_{0.75}$ bilayer and use them to demonstrate quasi-DC sensing up to […]
