Kavli Affiliate: Hector D. Abruna | First 5 Authors: Colin R. Bundschu, Mahdi Ahmadi, Juan F. Méndez-Valderrama, Yao Yang, Héctor D. Abruña | Summary: Precious-metal-free spinel oxide electrocatalysts are promising candidates for catalyzing the oxygen reduction reaction (ORR) in alkaline fuel cells. In this theory-driven study, we use joint density-functional theory in tandem with supporting […]

Kavli Affiliate: Darrell G. Schlom | First 5 Authors: L. Y. Shi, Zhenisbek Tagay, Jiahao Liang, Khoan Duong, Yi Wu | Summary: We present time-domain THz spectroscopy of thin films of the heavy-fermion superconductor CeCoIn$_5$. The complex optical conductivity is analyzed through a Drude model and extended Drude model analysis. Below the $approx$ 40 K […]

Kavli Affiliate: Jie Shan | First 5 Authors: Wenjin Zhao, Bowen Shen, Zui Tao, Sunghoon Kim, Patrick Knüppel | Summary: The interaction of a lattice of localized magnetic moments with a sea of conduction electrons in Kondo lattice models induces rich quantum phases of matter, such as Fermi liquids with heavily renormalized electronic quasiparticles, quantum […]

Kavli Affiliate: Alyosha Molnar | First 5 Authors: Stuart Daudlin, Anthony Rizzo, Sunwoo Lee, Devesh Khilwani, Christine Ou | Summary: Artificial intelligence (AI) hardware is positioned to unlock revolutionary computational abilities across diverse fields ranging from fundamental science [1] to medicine [2] and environmental science [3] by leveraging advanced semiconductor chips interconnected in vast distributed […]

Kavli Affiliate: David Muller | First 5 Authors: Emerson Melo, David Müller, , , | Summary: This paper establishes a connection between a category of discrete choice models and the realms of online learning and multiarmed bandit algorithms. Our contributions can be summarized in two key aspects. Firstly, we furnish sublinear regret bounds for a […]

Kavli Affiliate: Brett P. Fors | First 5 Authors: Steven J. Yang, Stephanie I. Rosenbloom, Brett P. Fors, Meredith N. Silberstein, | Summary: Phase-segregated polyureas (PU) have received considerable interest due to their use as tough, impact-resistant coatings. Polyureas are favored for these applications due to their mechanical strain rate sensitivity and energy dissipation. Predicting […]

Kavli Affiliate: Grace Xing | First 5 Authors: Len van Deurzen, Thai-Son Nguyen, Joseph Casamento, Huili Grace Xing, Debdeep Jena | Summary: We demonstrate epitaxial lattice-matched Al$_{0.89}$Sc$_{0.11}$N/GaN ten and twenty period distributed Bragg reflectors (DBRs) grown on c-plane bulk n-type GaN substrates by plasma-enhanced molecular beam epitaxy (PA-MBE). Resulting from a rapid increase of in-plane […]

Kavli Affiliate: Jie Shan | First 5 Authors: Phuong X. Nguyen, Liguo Ma, Raghav Chaturvedi, Kenji Watanabe, Takashi Taniguchi | Summary: Excitonic insulators (EIs), arising in semiconductors when the electron-hole binding energy exceeds the band gap, are a solid-state prototype for bosonic phases of matter. Unlike the charged excitations that are frozen and unable to […]
