Kavli Affiliate: Zheng Zhu | First 5 Authors: Yule Ma, Yule Ma, , , | Summary: Thermalization in isolated quantum systems is governed by the eigenstate thermalization hypothesis, while strong disorder can induce its breakdown via many-body localization. Here we show that disorder can also generate a narrow band of thermal eigenstates embedded in an […]
Kavli Affiliate: Yuji Tachikawa | First 5 Authors: Yuji Tachikawa, Yuji Tachikawa, , , | Summary: Strongly motivated by a mathematical result by Lin and Yamashita (arXiv:2412.02298), we describe a long exact sequence formed by groups of equivalence classes of two-dimensional $mathcalN=(0,1)$ supersymmetric quantum field theories (SQFTs) with and without $SU(2)$ symmetry. As an application, […]
Kavli Affiliate: Pau Amaro Seoane | First 5 Authors: Pau Amaro Seoane, Pau Amaro Seoane, , , | Summary: Stellar collisions in dense galactic nuclei might play an important role in fueling supermassive black holes (SMBHs) and shaping their environments. The gas released during these collisions can contribute to SMBH accretion, influencing phenomena such as […]
Kavli Affiliate: Chris Xu | First 5 Authors: The bbchallenge Collaboration, The bbchallenge Collaboration, , , | Summary: We prove that $S(5) = 47,176,870$ using the Coq proof assistant. The Busy Beaver value $S(n)$ is the maximum number of steps that an $n$-state 2-symbol Turing machine can perform from the all-zero tape before halting, and […]
Kavli Affiliate: Eliska Greplova | First 5 Authors: Thomas Spriggs, Thomas Spriggs, , , | Summary: We present a neural network wavefunction framework for solving non-Abelian lattice gauge theories in a continuous group representation. Using a combination of $SU(2)$ equivariant neural networks alongside an $SU(2)$ invariant, physics-inspired ansatz, we learn a parameterization of the ground […]
Kavli Affiliate: Masahito Yamazaki | First 5 Authors: Jun-ichi Sakamoto, Jun-ichi Sakamoto, , , | Summary: The four-dimensional Chern-Simons (CS) theory provides a systematic procedure for realizing two-dimensional integrable field theories. It is therefore a natural question to ask whether integrable deformations of the theories can be realized in the four-dimensional CS theory. In this […]

Kavli Affiliate: Lihong V. Wang | First 5 Authors: Lihong V. Wang, Lihong V. Wang, , , | Summary: We present a geometric interpretation of the hyperfine Breit–Rabi eigenvalues and eigenvectors in alkali atoms after reformulating the standard solution into a compact form. In this picture, the nuclear magnetic moment has a polar angle fixed […]
Kavli Affiliate: Eric Miller | First 5 Authors: Xi Long, Xi Long, , , | Summary: We present results from the Chandra X-ray Observatory Large Project (878 ks in 28 observations) of the Large Magellanic Cloud supernova remnant N132D. We measure the expansion of the forward shock in the bright southern rim to be $0.!^primeprime10 […]
Kavli Affiliate: David A. Muller | First 5 Authors: Felix Bennemann, Felix Bennemann, , , | Summary: High-resolution transmission electron microscopy (HRTEM) is an important method for imaging beam sensitive materials often under cryo conditions. Electron ptychography in the scanning transmission electron microscope (STEM) has been shown to reconstruct low-noise phase data at a reduced […]
