Kavli Affiliate: Gary A. Steele | First 5 Authors: Mario F. Gely, Adrián Sanz Mora, Shun Yanai, Rik van der Spek, Daniel Bothner | Summary: Nonlinear damping, the change in damping rate with the amplitude of oscillations plays an important role in many electrical, mechanical and even biological oscillators. In novel technologies such as carbon […]
Kavli Affiliate: David J. Gross | First 5 Authors: David J. Gross, Vladimir Rosenhaus, , , | Summary: Motivated by the desire to understand chaos in the $S$-matrix of string theory, we study tree level scattering amplitudes involving highly excited strings. While the amplitudes for scattering of light strings have been a hallmark of string […]
Kavli Affiliate: Liedewij Laan | First 5 Authors: Christine Linne, Daniele Visco, Stefano Angioletti-Uberti, Liedewij Laan, Daniela J. Kraft | Summary: Reliably distinguishing between cells based on minute differences in receptor density is crucial for cell-cell or virus-cell recognition, the initiation of signal transduction and selective targeting in directed drug delivery. Such sharp differentiation between […]
Kavli Affiliate: Daniel Needleman | First 5 Authors: Brian D Leahy, Catherine Racowsky, Daniel Needleman, , | Summary: Macroscopic, phenomenological models have proven useful as concise framings of our understandings in fields from statistical physics to economics to biology. Constructing a phenomenological model for development would provide a framework for understanding the complicated, regulatory nature […]

Kavli Affiliate: Paul L. McEuen | First 5 Authors: Tianyi Han, Jixiang Yang, Qihang Zhang, Lei Wang, Kenji Watanabe | Summary: Monolayer graphene aligned with hexagonal boron nitride (hBN) develops a gap at the charge neutrality point (CNP). This gap has previously been extensively studied by electrical transport through thermal activation measurements. Here, we report […]
Kavli Affiliate: Lara A. Estroff | First 5 Authors: Jiseok Gim, Alden Koch, Laura M. Otter, Benjamin H. Savitzky, Sveinung Erland | Summary: A pearl’s distinguished beauty and toughness are attributable to the periodic stacking of aragonite tablets known as nacre. Nacre has naturally occurring mesoscale periodicity that remarkably arises in the absence of discrete […]
Kavli Affiliate: Timon Idema | First 5 Authors: Carsten T. van de Kamp, George Dadunashvili, Johan L. A. Dubbeldam, Timon Idema, | Summary: Order can spontaneously emerge from seemingly noisy interactions between biological agents, like a flock of birds changing their direction of flight in unison, without a leader or an external cue. We are […]
Kavli Affiliate: Patricia R. Burchat | First 5 Authors: Javier Sanchez, Ismael Mendoza, David P. Kirkby, Patricia R. Burchat, | Summary: In Stage-IV imaging surveys, a significant amount of the cosmologically useful information is due to sources whose images overlap with those of other sources on the sky. The cosmic shear signal is primarily encoded […]
Kavli Affiliate: Peidong Yang | First 5 Authors: Li Na Quan, Yoonjae Park, Peijun Guo, Mengyu Gao, Jianbo Jin | Summary: Organic-inorganic layered perovskites are two-dimensional quantum wells with layers of lead-halide octahedra stacked between organic ligand barriers. The combination of their dielectric confinement and ionic sublattice results in excitonic excitations with substantial binding energies […]
