Cell Division and Motility Enable Hexatic Order in Biological Tissues

Kavli Affiliate: Mark J. Bowick | First 5 Authors: Yiwen Tang, Siyuan Chen, Mark J. Bowick, Dapeng Bi, | Summary: Biological tissues transform between solid-like and liquid-like states in many fundamental physiological events. Recent experimental observations further suggest that in two-dimensional epithelial tissues these solid-liquid transformations can happen via intermediate states akin to the intermediate […]

A “morphogenetic action” principle for 3D shape formation by the growth of thin sheets

Kavli Affiliate: Boris I. Shraiman | First 5 Authors: Dillon J. Cislo, Anastasios Pavlopoulos, Boris I. Shraiman, , | Summary: How does growth encode form in developing organisms? Many different spatiotemporal growth profiles may sculpt tissues into the same target 3D shapes, but only specific growth patterns are observed in animal and plant development. In […]

Magnetostriction, piezomagnetism and domain nucleation in a kagome antiferromagnet

Kavli Affiliate: Leon Balents | First 5 Authors: Qingkai Meng, Jianting Dong, Pan Nie, Liangcai Xu, Jinhua Wang | Summary: Whenever the elastic energy of a solid depends on magnetic field, there is a magnetostrictive response. Field-linear magnetostriction implies piezomagnetism and vice versa. Here, we show that Mn$_3$Sn, a non-collinear antiferromanget with Weyl nodes, hosts […]

A $j_{rm eff}=1/2$ Kitaev material on the triangular lattice: The case of NaRuO$_2$

Kavli Affiliate: Leon Balents | First 5 Authors: Aleksandar Razpopov, David A. S. Kaib, Steffen Backes, Leon Balents, Stephen D. Wilson | Summary: Motivated by recent reports of a quantum disordered ground state in the triangular lattice compound NaRuO$_2$, we derive a $j_{rm eff}=1/2$ magnetic model for this system by means of first-principles calculations. The […]

The inflation hierarchy and the polarization hierarchy are complete for the quantum bilocal scenario

Kavli Affiliate: David Gross | First 5 Authors: Laurens T. Ligthart, David Gross, , , | Summary: It is a fundamental but difficult problem to characterize the set of correlations that can be obtained by performing measurements on quantum mechanical systems. The problem is particularly challenging when the preparation procedure for the quantum states is […]

Spatiotemporal control of active topological defects

Kavli Affiliate: Mark J. Bowick | First 5 Authors: Suraj Shankar, Luca V. D. Scharrer, Mark J. Bowick, M. Cristina Marchetti, | Summary: Topological defects play a central role in the physics of many materials, including magnets, superconductors and liquid crystals. In active fluids, defects become autonomous particles that spontaneously propel from internal active stresses […]

The role of non-affine deformations in the elastic behavior of the cellular vertex model

Kavli Affiliate: Mark J. Bowick | First 5 Authors: Michael F. Staddon, Arthur Hernandez, Mark J. Bowick, Michael Moshe, M. Cristina Marchetti | Summary: The vertex model of epithelia describes the apical surface of a tissue as a tiling of polygonal cells, with a mechanical energy governed by deviations in cell shape from preferred, or […]

RenderDiffusion: Image Diffusion for 3D Reconstruction, Inpainting and Generation

Kavli Affiliate: Matthew Fisher | First 5 Authors: Titas Anciukevicius, Zexiang Xu, Matthew Fisher, Paul Henderson, Hakan Bilen | Summary: Diffusion models currently achieve state-of-the-art performance for both conditional and unconditional image generation. However, so far, image diffusion models do not support tasks required for 3D understanding, such as view-consistent 3D generation or single-view object […]
