Kavli Affiliate: David Gross | First 5 Authors: Laurens T. Ligthart, Mariami Gachechiladze, David Gross, , | Summary: A causal structure is a description of the functional dependencies between random variables. A distribution is compatible with a given causal structure if it can be realized by a process respecting these dependencies. Deciding whether a distribution […]
Kavli Affiliate: Lars Bildsten | First 5 Authors: William C. Schultz, Lars Bildsten, Yan-Fei Jiang, , | Summary: Increasing main sequence stellar luminosity with stellar mass leads to the eventual dominance of radiation pressure in stellar envelope hydrostatic balance. As the luminosity approaches the Eddington limit, additional instabilities (beyond conventional convection) can occur. These instabilities […]
Kavli Affiliate: Lars Bildsten | First 5 Authors: Thomas Kupfer, Evan B. Bauer, Jan van Roestel, Eric C. Bellm, Lars Bildsten | Summary: We present the discovery of a new double detonation progenitor system consisting of a hot subdwarf B (sdB) binary with a white dwarf companion with an P=76.34179(2) min orbital period. Spectroscopic observations […]
Kavli Affiliate: Matthew Fisher | First 5 Authors: Difan Liu, Matthew Fisher, Aaron Hertzmann, Evangelos Kalogerakis, | Summary: This paper introduces a model for producing stylized line drawings from 3D shapes. The model takes a 3D shape and a viewpoint as input, and outputs a drawing with textured strokes, with variations in stroke thickness, deformation, […]
Kavli Affiliate: Lars Bildsten | First 5 Authors: Jared A. Goldberg, Yan-Fei Jiang, Lars Bildsten, , | Summary: We explore the three-dimensional properties of convective, luminous ($Lapprox10^{4.5}-10^{5}L_odot$), Hydrogen-rich envelopes of Red Supergiants (RSGs) based on radiation hydrodynamic simulations in spherical geometry using $texttt{Athena++}$. These computations comprise $approx30%$ of the stellar volume, include gas and radiation […]
Kavli Affiliate: Matthew P. A. Fisher | First 5 Authors: Yaodong Li, Romain Vasseur, Matthew P. A. Fisher, Andreas W. W. Ludwig, | Summary: We introduce an exact mapping of Clifford (stabilizer) random tensor networks (RTNs) and monitored quantum circuits, onto a statistical mechanics model. With Haar unitaries, the fundamental degrees of freedom (‘spins’) are […]
Kavli Affiliate: Lars Bildsten | First 5 Authors: Tin Long Sunny Wong, Lars Bildsten, , , | Summary: We calculate the stellar evolution of both white dwarfs (WDs) in AM CVn binaries with orbital periods of $P_{mathrm{orb}} approx 5-70$ minutes. We focus on the cases where the donor starts as a $M_{mathrm{He}} < 0.2 , […]
Kavli Affiliate: Leon Balents | First 5 Authors: Xiaokang Li, Shan Jiang, Qingkai Meng, Huakun Zuo, Zengwei Zhu | Summary: The magnetic free energy is usually quadratic in magnetic field and depends on the mutual orientation of the magnetic field and the crystalline axes. Tiny in magnitude, this magnetocrystalline anisotropy energy (MAE) is nevertheless indispensable […]
Kavli Affiliate: Mark J. Bowick | First 5 Authors: Arthur Hernandez, Michael F. Staddon, Mark J. Bowick, M. Cristina Marchetti, Michael Moshe | Summary: Vertex Models, as used to describe cellular tissue, have an energy controlled by deviations from both a target area and a target perimeter. The constrained nonlinear relation between area and perimeter, […]
Kavli Affiliate: Mark J. Bowick | First 5 Authors: Arthur Hernandez, Michael F. Staddon, Mark J. Bowick, M. Cristina Marchetti, Michael Moshe | Summary: Vertex Models, as used to describe cellular tissue, have an energy controlled by deviations of each cell area and perimeter from target values. The constrained nonlinear relation between area and perimeter […]
