Turbulence Supported Massive Star Envelopes

Kavli Affiliate: Lars Bildsten | First 5 Authors: William Schultz, Lars Bildsten, Yan-Fei Jiang, , | Summary: The outer envelopes of massive ($Mgtrsim10,M_{odot}$) stars exhibit large increases in opacities from forests of lines and ionization transitions (particularly from iron and helium) that trigger near-surface convection zones. One-dimensional models predict density inversions and supersonic motions that […]

Realization of two-sublattice exchange physics in the triangular lattice compound Ba3Er(BO3)3

Kavli Affiliate: Leon Balents | First 5 Authors: Matthew Ennis, Rabindranath Bag, Chunxiao Liu, Sachith E. Dissanayake, Alexander I. Kolesnikov | Summary: We have synthesized high-quality single crystal samples of the erbium-based triangular lattice compound Ba3Er(BO3)3. Thermal and magnetic measurements reveal large anisotropy and a possible phase transition at 100 mK. The low-temperature magnetic heat […]

Excitations of quantum Ising chain CoNb2O6 in low transverse field: quantitative description of bound states stabilized by off-diagonal exchange and applied field

Kavli Affiliate: Leon Balents | First 5 Authors: Leonie Woodland, Izabella Lovas, M. Telling, D. Prabhakaran, Leon Balents | Summary: We present experimental and theoretical evidence of novel bound state formation in the low transverse field ordered phase of the quasi-one-dimensional Ising-like material CoNb$_2$O$_6$. High resolution single crystal inelastic neutron scattering measurements observe that small […]

Universality of the cross entropy in $mathbb{Z}_2$ symmetric monitored quantum circuits

Kavli Affiliate: Matthew P. A. Fisher | First 5 Authors: Maria Tikhanovskaya, Ali Lavasani, Matthew P. A. Fisher, Sagar Vijay, | Summary: The linear cross-entropy (LXE) has been recently proposed as a scalable probe of the measurement-driven phase transition between volume- and area-law-entangled phases of pure-state trajectories in certain monitored quantum circuits. Here, we demonstrate […]

Control4D: Dynamic Portrait Editing by Learning 4D GAN from 2D Diffusion-based Editor

Kavli Affiliate: Cheng Peng | First 5 Authors: Ruizhi Shao, Jingxiang Sun, Cheng Peng, Zerong Zheng, Boyao Zhou | Summary: Recent years have witnessed considerable achievements in editing images with text instructions. When applying these editors to dynamic scene editing, the new-style scene tends to be temporally inconsistent due to the frame-by-frame nature of these […]
