Kavli Affiliate: Joel E. Moore | First 5 Authors: Maxime Dupont, Joel E. Moore, , , | Summary: Quantum criticality emerges from the collective behavior of many interacting quantum particles, often at the transition between different phases of matter. It is one of the cornerstones of condensed matter physics, which we access on noisy intermediate-scale […]
Kavli Affiliate: Grace Xing | First 5 Authors: Len van Deurzen, Ryan Page, Vladimir Protasenko, Huili, Xing | Summary: We demonstrate the first optically pumped sub-300 nm UV laser structures grown by plasma-assisted molecular beam epitaxy on single-crystal bulk AlN. The edge-emitting laser structures fabricated with the AlN/AlGaN heterostructures exhibit multi-mode emission with peak gain […]
Kavli Affiliate: Xiang Zhang | First 5 Authors: Yihang Yin, Qingzhong Wang, Siyu Huang, Haoyi Xiong, Xiang Zhang | Summary: Contrastive learning has been widely applied to graph representation learning, where the view generators play a vital role in generating effective contrastive samples. Most of the existing contrastive learning methods employ pre-defined view generation methods, […]
Kavli Affiliate: Lena F. Kourkoutis | First 5 Authors: Grace A. Pan, Dan Ferenc Segedin, Harrison LaBollita, Qi Song, Emilian M. Nica | Summary: Since the discovery of high-temperature superconductivity in the copper oxide materials, there have been sustained efforts to both understand the origins of this phase and discover new cuprate-like superconducting materials. One […]
Kavli Affiliate: Wei Gao | First 5 Authors: Bo Ai, Wei Gao, Vinay, David Hsu, | Summary: How can a robot navigate successfully in a rich and diverse environment, indoors or outdoors, along an office corridor or a trail in the park, on the flat ground, the staircase, or the elevator, etc.? To this end, […]
Kavli Affiliate: Wei Gao | First 5 Authors: Bo Ai, Wei Gao, Vinay, David Hsu, | Summary: How can a robot navigate successfully in rich and diverse environments, indoors or outdoors, along office corridors or trails on the grassland, on the flat ground or the staircase? To this end, this work aims to address three […]
Kavli Affiliate: Michael F. Crommie | First 5 Authors: Franklin Liou, Hsin-Zon Tsai, Andrew S. Aikawa, Kyler C. Natividad, Eric Tang | Summary: The spatial arrangement of adsorbates deposited onto a clean surface in vacuum typically cannot be reversibly tuned. Here we use scanning tunneling microscopy to demonstrate that molecules deposited onto graphene field-effect transistors […]
Kavli Affiliate: Wei Gao | First 5 Authors: Wei Gao, Jie Chen, Cédric Richard, Wentao Shi, Qunfei Zhang | Summary: The recursive least-squares algorithm with $ell_1$-norm regularization ($ell_1$-RLS) exhibits excellent performance in terms of convergence rate and steady-state error in identification of sparse systems. Nevertheless few works have studied its stochastic behavior, in particular its […]
Kavli Affiliate: Herre Van Der Zant | First 5 Authors: Eugenia Pyurbeeva, Chunwei Hsu, David Vogel, Christina Wegeberg, Marcel Mayor | Summary: Single molecules are nanoscale thermodynamic systems with few degrees of freedom. Thus, the knowledge of their entropy can reveal the presence of microscopic electron transfer dynamics, that are difficult to observe otherwise. Here, […]
Kavli Affiliate: Paul W. K. Rothemund | First 5 Authors: Tyler D. Ross, Dino Osmanović, John F. Brady, Paul W. K. Rothemund, | Summary: Snell’s law, which encompasses both refraction and total internal reflection, provides the foundation for ray optics and all lens-based instruments, from microscopes to telescopes. Refraction results when light crosses the interface […]
