Numerical Simulations of Convective 3-Dimensional Red Supergiant Envelopes

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 […]

Numerical evidence for a Haagerup conformal field theory

Kavli Affiliate: Yuji Tachikawa | First 5 Authors: Tzu-Chen Huang, Ying-Hsuan Lin, Kantaro Ohmori, Yuji Tachikawa, Masaki Tezuka | Summary: We numerically study an anyon chain based on the Haagerup fusion category, and find evidence that it leads in the long-distance limit to a conformal field theory whose central charge is $sim 2$. Fusion categories […]

Statistical Mechanics Model for Clifford Random Tensor Networks and Monitored Quantum Circuits

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 […]

Relative Entropy Gradient Sampler for Unnormalized Distributions

Kavli Affiliate: Feng Yuan | First 5 Authors: Xingdong Feng, Yuan Gao, Jian Huang, Yuling Jiao, Xu Liu | Summary: We propose a relative entropy gradient sampler (REGS) for sampling from unnormalized distributions. REGS is a particle method that seeks a sequence of simple nonlinear transforms iteratively pushing the initial samples from a reference distribution […]
