Simulating Hydrodynamics in Cosmology with CRK-HACC

Kavli Affiliate: Katrin Heitmann | First 5 Authors: Nicholas Frontiere, J. D. Emberson, Michael Buehlmann, Joseph Adamo, Salman Habib | Summary: We introduce CRK-HACC, an extension of the Hardware/Hybrid Accelerated Cosmology Code (HACC), to resolve gas hydrodynamics in large-scale structure formation simulations of the universe. The new framework couples the HACC gravitational N-body solver with […]

Constraining Dark matter annihilation with Dark Energy Survey Y3 LSBG sample

Kavli Affiliate: Masahiro Takada | First 5 Authors: Daiki Hashimoto, Atsushi J. Nishizawa, Masahiro Takada, , | Summary: To reveal natures of the dark matter (DM) particles, a gamma-ray signal produced in annihilation processes of DM into the standard model particles has been one of the major probes. The cross-correlation between highly DM dominated structures, […]

An Optimally-Tuned Starting Point for Single-Shot $GW$ Calculations of Solids

Kavli Affiliate: Jeffrey B. Neaton | First 5 Authors: Stephen E. Gant, Jonah B. Haber, Marina R. Filip, Francisca Sagredo, Dahvyd Wing | Summary: The dependence of ab initio many-body perturbation theory within the $GW$ approximation on the eigensystem used in calculating quasiparticle corrections limits this method’s predictive power. Here, we investigate the accuracy of […]

Rapid discovery of cathodes, ionic conductors and solid-state electrolytes through topological migration analysis

Kavli Affiliate: Kristin A. Persson | First 5 Authors: Jimmy-Xuan Shen, Haoming Howard Li, Ann C. Rutt, Matthew K. Horton, Kristin A. Persson | Summary: We present a graph-theoretic analysis framework for ion migration in solid-state materials. The nodes of the graph are the metastable sites of the cation and the edges are discrete migration […]

AutoDistil: Few-shot Task-agnostic Neural Architecture Search for Distilling Large Language Models

Kavli Affiliate: Xiang Zhang | First 5 Authors: Dongkuan Xu, Subhabrata Mukherjee, Xiaodong Liu, Debadeepta Dey, Wenhui Wang | Summary: Knowledge distillation (KD) methods compress large models into smaller students with manually-designed student architectures given pre-specified computational cost. This requires several trials to find a viable student, and further repeating the process for each student […]

Stable pairs and Gopakumar-Vafa type invariants on holomorphic symplectic 4-folds

Kavli Affiliate: Yukinobu Toda | First 5 Authors: Yalong Cao, Georg Oberdieck, Yukinobu Toda, , | Summary: As an analogy to Gopakumar-Vafa conjecture on Calabi-Yau 3-folds, Klemm-Pandharipande defined Gopakumar-Vafa type invariants of a Calabi-Yau 4-fold $X$ using Gromov-Witten theory. When $X$ is holomorphic symplectic, Gromov-Witten invariants vanish and one can consider the corresponding reduced theory. […]
