Surface curvature guides early construction activity in mound-building termites

Kavli Affiliate: Radhika Nagpal | First 5 Authors: Daniel S. Calovi, Paul Bardunias, Nicole Carey, J. Scott Turner, Radhika Nagpal | Summary: Termite colonies construct towering, complex mounds, in a classic example of distributed agents coordinating their activity via interaction with a shared environment. The traditional explanation for how this coordination occurs focuses on the […]

Jetting to dripping transition: critical aspect ratio in step emulsifiers

Kavli Affiliate: David Weitz | First 5 Authors: Andrea Montessori, Marco Lauricella, Elad Stolovicki, David Weitz, Sauro Succi | Summary: Fully three-dimensional, time-dependent, direct simulations of the non-ideal Navier-Stokes equations for a two-component fluid, shed light into the mechanism which inhibits droplet breakup in step emulsifiers below a critical threshold of the the width-to-height ($w/h$) […]

Uncovering the dynamic precursors to motor-driven contraction of active gels

Kavli Affiliate: Gijsje Koenderink | First 5 Authors: Jose Alvarado, Luca Cipelletti, Gijsje Koenderink, , | Summary: Cells and tissues have the remarkable ability to actively generate the forces required to change their shape. This active mechanical behavior is largely mediated by the actin cytoskeleton, a crosslinked network of actin filaments that is contracted by […]

Ground motion prediction at gravitational wave observatories using archival seismic data

Kavli Affiliate: Richard Mittleman | First 5 Authors: Nikhil Mukund, Michael Coughlin, Jan Harms, Sebastien Biscans, Jim Warner | Summary: Gravitational wave observatories have always been affected by tele-seismic earthquakes leading to a decrease in duty cycle and coincident observation time. In this analysis, we leverage the power of machine learning algorithms and archival seismic […]

Candidate Massive Galaxies at $z sim 4$ in the Dark Energy Survey

Kavli Affiliate: Rafe Schindler | First 5 Authors: Pierandrea Guarnieri, Claudia Maraston, Daniel Thomas, Janine Pforr, Violeta Gonzalez-Perez | Summary: Using stellar population models, we predicted that the Dark Energy Survey (DES) – due to its special combination of area (5000 deg. sq.) and depth ($i = 24.3$) – would be in the position to […]

Magnifications of paired micro-images emerging from a micro-lensing critical curve

Kavli Affiliate: Paul Schechter | First 5 Authors: Luke Weisenbach, Paul Schechter, Joachim Wambsganss, , | Summary: Studies of the inner regions of micro-lensed AGN during caustic crossing events have often relied upon the approximation that the magnification near a fold caustic is inversely proportional to the square root of the source-caustic distance. We examine […]

Untethered microbot powered by giant magnetoelastic strain

Kavli Affiliate: Zhigang Suo | First 5 Authors: Yukun Xia, Jikun Wang, Ruisen Yang, Tongqing Lu, Tiejun Wang | Summary: Magnetic elastomers deform under a magnetic field, working as a soft actuator. Untethered microbot made of magnetic elastomers have great potentials in performing medical tasks inside human body as mini doctors. However, the lack of […]

Transport signatures of surface states in a Weyl semimetal: evidence of field driven Fermi arc interferometry

Kavli Affiliate: Jeffrey Neaton | First 5 Authors: Nityan L. Nair, Marie-Eve Boulanger, Francis Laliberté, Sinead Griffin, Sanyum Channa | Summary: A signature property of Weyl semimetals is the existence of topologically protected surface states – arcs in momentum space that connect Weyl points in the bulk. However, the presence of bulks states makes detection […]

Andreev reflection at the interface with an oxide in the quantum Hall regime

Kavli Affiliate: Joseph Falson | First 5 Authors: Yusuke Kozuka, Atsushi Sakaguchi, Joseph Falson, Atsushi Tsukazaki, Masashi Kawasaki | Summary: Quantum Hall/superconductor junctions have been an attractive topic as the two macroscopically quantum states join at the interface. Despite longstanding efforts, however, experimental understanding of this system has not been settled yet. One of the […]
