Structure and dynamics of motor-driven microtubule bundles

Kavli Affiliate: Daniel J. Needleman | First 5 Authors: Bezia Lemma, Linnea Lemma, Stephanie C. Ems-McClung, Claire E. Walczak, Zvonimir Dogic | Summary: Connecting the large-scale emergent behaviors of active materials to the microscopic properties of their constituents is a challenge due to a lack of data on the multiscale dynamics and structure of such […]

Dynamics of Time-Modulated, Nonlinear Phononic Lattices

Kavli Affiliate: Chiara Daraio | First 5 Authors: Brian L. Kim, Christoper Chong, Setare Hajarolasvadi, Yifan Wang, Chiara Daraio | Summary: The propagation of acoustic and elastic waves in time-varying, spatially homogeneous media can exhibit different phenomena when compared to traditional spatially-varying, temporally-homogeneous media. In the present work, the response of a one-dimensional phononic lattice […]

Ab Initio Calculations of XUV Ground and Excited States for First-Row Transition Metal Oxides

Kavli Affiliate: Scott K. Cushing | First 5 Authors: Isabel M. Klein, Alex Krotz, Jonathan M. Michelsen, Scott K. Cushing, | Summary: Transient X-ray spectroscopies have become ubiquitous in studying photoexcited dynamics in solar energy materials due to their sensitivity to carrier occupations and local chemical or structural dynamics. The interpretation of solid-state photoexcited dynamics, […]

Polarized Blazar X-rays imply particle acceleration in shocks

Kavli Affiliate: Herman L. Marshall | First 5 Authors: Ioannis Liodakis, Alan P. Marscher, Iván Agudo, Andrei V. Berdyugin, Maria I. Bernardos | Summary: Most of the light from blazars, active galactic nuclei with jets of magnetized plasma that point nearly along the line of sight, is produced by high-energy particles, up to $sim 1$ […]

Categorical and K-theoretic Donaldson-Thomas theory of $mathbb{C}^3$ (part II)

Kavli Affiliate: Yukinobu Toda | First 5 Authors: Tudor Pădurariu, Yukinobu Toda, , , | Summary: Quasi-BPS categories appear as summands in semiorthogonal decompositions of DT categories for Hilbert schemes of points in the three dimensional affine space and in the categorical Hall algebra of the two dimensional affine space. In this paper, we prove […]
