Kavli Affiliate: Michael F. Crommie | First 5 Authors: Hongyuan Li, Shaowei Li, Mit H. Naik, Jingxu Xie, Xinyu Li | Summary: Moir’e superlattices in transition metal dichalcogenide (TMD) heterostructures can host novel correlated quantum phenomena due to the interplay of narrow moir’e flat bands and strong, long-range Coulomb interactions1-5. However, microscopic knowledge of the […]
Kavli Affiliate: Felix Fischer | First 5 Authors: José Correa, Paul Dütting, Felix Fischer, Kevin Schewior, Bruno Ziliotto | Summary: A prophet inequality states, for some $alphain[0,1]$, that the expected value achievable by a gambler who sequentially observes random variables $X_1,dots,X_n$ and selects one of them is at least an $alpha$ fraction of the maximum […]
Kavli Affiliate: Eli Yablonovitch | First 5 Authors: Sri Krishna Vadlamani, Tianyao Patrick Xiao, Eli Yablonovitch, , | Summary: Optimization is a major part of human effort. While being mathematical, optimization is also built into physics. For example, physics has the principle of Least Action, the principle of Minimum Entropy Generation, and the Variational Principle. […]

Kavli Affiliate: Michael Brenner | First 5 Authors: Arunachalam Narayanaswamy, Subhashini Venugopalan, Dale R. Webster, Lily Peng, Greg Corrado | Summary: Model explanation techniques play a critical role in understanding the source of a model’s performance and making its decisions transparent. Here we investigate if explanation techniques can also be used as a mechanism for […]

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: Shmuel M. Rubinstein | First 5 Authors: Sam Dillavou, Yohai Bar Sinai, Michael P Brenner, Shmuel M Rubinstein, | Summary: Classically, the quantity of contact area $A_R$ between two bodies is considered a proxy for the force of friction. However, bond density across the interface – quality of contact – is also relevant, […]
Kavli Affiliate: Kerry Vahala | First 5 Authors: Peter Plavchan, Gautam Vasisht, Chas Beichman, Heather Cegla, Xavier Dumusque | Summary: EarthFinder is a NASA Astrophysics Probe mission concept selected for study as input to the 2020 Astrophysics National Academies Decadal Survey. The EarthFinder concept is based on a dramatic shift in our understanding of how […]
Kavli Affiliate: David A. Weitz | First 5 Authors: Andrea Montessori, Marco Lauricella, Sauro Succi, Elad Stolovicki, David A. Weitz | Summary: Three-dimensional, time-dependent direct simulations of step emulsification micro-devices highlight two essential mechanisms for droplet formation: first, the onset of an adverse pressure gradient driving a back-flow of the continuous phase from the external […]
