Random Quantum Circuits

Kavli Affiliate: Matthew P. A. Fisher | First 5 Authors: Matthew P. A. Fisher, Vedika Khemani, Adam Nahum, Sagar Vijay, | Summary: Quantum circuits — built from local unitary gates and local measurements — are a new playground for quantum many-body physics and a tractable setting to explore universal collective phenomena far-from-equilibrium. These models have […]

3D Hydrodynamics of Pre-supernova Outbursts in Convective Red Supergiant Envelopes

Kavli Affiliate: Lars Bildsten | First 5 Authors: Benny T. -H. Tsang, Daniel Kasen, Lars Bildsten, , | Summary: Eruptive mass loss likely produces the energetic outbursts observed from some massive stars before they undergo core-collapse supernovae (CCSNe). The resulting dense circumstellar medium (CSM) may also cause the subsequent SNe to be observed as Type […]

Spotting Temporally Precise, Fine-Grained Events in Video

Kavli Affiliate: Matthew Fisher | First 5 Authors: James Hong, Haotian Zhang, Michaël Gharbi, Matthew Fisher, Kayvon Fatahalian | Summary: We introduce the task of spotting temporally precise, fine-grained events in video (detecting the precise moment in time events occur). Precise spotting requires models to reason globally about the full-time scale of actions and locally […]

Active nematic defects in compressible and incompressible flows

Kavli Affiliate: Mark J. Bowick | First 5 Authors: Supavit Pokawanvit, Zhitao Chen, Zhihong You, Luiza Angheluta, M. Cristina Marchetti | Summary: We study two-dimensional active nematics on a substrate, comparing compressible and incompressible flows. Through simulations and theoretical analysis we show that arch patterns are stable in the compressible case but are unstable in […]

Phonon Thermal Hall Conductivity from Scattering with Collective Fluctuations

Kavli Affiliate: Leon Balents | First 5 Authors: Léo Mangeolle, Leon Balents, Lucile Savary, , | Summary: Because electrons and ions form a coupled system, it is a priori clear that the dynamics of the lattice should reflect symmetry breaking within the electronic degrees of freedom. This has been recently clearly evidenced for the case […]

Shock Breakout in 3-Dimensional Red Supergiant Envelopes

Kavli Affiliate: Lars Bildsten | First 5 Authors: Jared A. Goldberg, Yan-fei Jiang, Lars Bildsten, , | Summary: Using Athena++, we perform 3D Radiation-Hydrodynamic calculations of the radiative breakout of the shock wave in the outer envelope of a red supergiant (RSG) which has suffered core collapse and will become a Type IIP supernova. The […]

Minimising statistical errors in calibration of quantum-gate sets

Kavli Affiliate: David Gross | First 5 Authors: Yaiza Aragonés-Soria, René Otten, Tobias Hangleiter, Pascal Cerfontaine, David Gross | Summary: Calibration of quantum gates is a necessary hurdle to overcome on the way to a reliable quantum computer. In a recent paper, a protocol called Gate Set Calibration protocol (GSC) has been introduced and used […]

APES: Articulated Part Extraction from Sprite Sheets

Kavli Affiliate: Matthew Fisher | First 5 Authors: Zhan Xu, Matthew Fisher, Yang Zhou, Deepali Aneja, Rushikesh Dudhat | Summary: Rigged puppets are one of the most prevalent representations to create 2D character animations. Creating these puppets requires partitioning characters into independently moving parts. In this work, we present a method to automatically identify such […]
