Kavli Affiliate: Farhan Rana | First 5 Authors: Farhan Rana, Okan Koksal, Minwoo Jung, Gennady Shvets, Christina Manolatou | Summary: Optical absorption and emission spectra of doped two-dimensional (2D) materials exhibit sharp peaks that are often identified with pure excitons and pure trions (or charged excitons), but both peaks have been recently attributed to superpositions […]

Kavli Affiliate: Itai Cohen | First 5 Authors: Yuchao Chen, Yunus A. Kinkhabwala, Boris Barron, Matthew Hall, Tomas A. Arias | Summary: Decisions regarding housing, transportation, and resource allocation would all benefit from accurate small-area population forecasts. While various tried-and-tested forecast methods exist at regional scales, developing an accurate neighborhood-scale forecast remains a challenge partly […]

Kavli Affiliate: Kinfai Mak | First 5 Authors: Mahmut Mak, Mahmut Mak, , , | Summary: In this study, we introduce the natural mate and conjugate mate of a Frenet curve in a three dimensional Lie group $ mathbbG $ with bi-invariant metric. Also, we give some relationships between a Frenet curve and its natural […]

Kavli Affiliate: Darrell Schlom | First 5 Authors: Sourav Dutta, Abhishek Khanna, Adou S. Assoa, Hanjong Paik, Darrell Schlom | Summary: Computationally hard problems, including combinatorial optimization, can be mapped into the problem of finding the ground-state of an Ising Hamiltonian. Building physical systems with collective computational ability and distributed parallel processing capability can accelerate […]

Kavli Affiliate: Gregory D. Fuchs | First 5 Authors: Albert M. Park, Zhen Chen, Xiyue S. Zhang, Lijun Zhu, David A. Muller | Summary: Magnetic skyrmions hold promise for spintronic devices. To explore the dynamical properties of skyrmions in devices, a nanoscale method to image spin textures in response to a stimulus is essential. Here, […]

Kavli Affiliate: Paul L. McEuen | First 5 Authors: Baris Bircan, Marc Z. Miskin, Robert J. Lang, Michael C. Cao, Kyle J. Dorsey | Summary: Origami design principles are scale invariant and enable direct miniaturization of origami structures provided the sheets used for folding have equal thickness to length ratios. Recently, seminal steps have been […]

Kavli Affiliate: Jie Shan | First 5 Authors: Zhixin Li, Zhixin Li, , , | Summary: Building models are conventionally reconstructed by building roof points planar segmentation and then using a topology graph to group the planes together. Roof edges and vertices are then mathematically represented by intersecting segmented planes. Technically, such solution is based […]

Kavli Affiliate: Christopher Ober| First 5 Authors: Sebastian W. Ober, Sebastian W. Ober, , , | Summary:We consider the optimal approximate posterior over the top-layer weights in a Bayesian neural network for regression, and show that it exhibits strong dependencies on the lower-layer weights. We adapt this result to develop a correlated approximate posterior over […]

Kavli Affiliate: Gregory D. Fuchs | First 5 Authors: Raphaël S. Daveau, Tom Vandekerckhove, Arunabh Mukherjee, Zefang Wang, Jie Shan | Summary: Monolayer WSe$_2$ hosts bright single-photon emitters. Because of its compliance, monolayer WSe$_2$ conforms to patterned substrates without breaking, thus creating the potential for large local strain, which is one activation mechanism of its […]
