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: Stephan Rauschenbach | Summary:Using electrospray ion beam deposition, we collide the complex molecule Reichardt’s Dye (C41H30NO+) at low, hyperthermal translational energy (2-50 eV) with a Cu(100) surface and image the outcome at single-molecule level by scanning tunneling microscopy. We observe bond-selective reaction induced by the translational kinetic energy. The collision impulse compresses the […]
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: 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 […]
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: Michael Crommie | First 5 Authors: Kyunghoon Lee, M. Iqbal Bakti Utama, Salman Kahn, Appalakondaiah Samudrala, Nicolas Leconte | Summary: Two-dimensional heterostructures with layers of slightly different lattice vectors exhibit a new periodic structure known as moire lattices. Moire lattice formation provides a powerful new way to engineer the electronic structure of two-dimensional […]
Kavli Affiliate: Achillefs Kapanidis | Summary:Single-molecule Förster resonance energy transfer (smFRET) has become a mainstream technique for probing biomolecular structural dynamics. The rapid and wide adoption of the technique by an ever-increasing number of groups has generated many improvements and variations in the technique itself, in methods for sample preparation and characterization, in analysis of […]
Kavli Affiliate: Kristin A. Persson | First 5 Authors: Nathan C. Frey, Matthew K. Horton, Jason M. Munro, Sinéad M. Griffin, Kristin A. Persson | Summary: The discovery of intrinsic magnetic topological order in $rm MnBi_2Te_4$ has invigorated the search for materials with coexisting magnetic and topological phases. These multi-order quantum materials are expected to […]
