OPTIMADE, an API for exchanging materials data

Kavli Affiliate: Kristin A. Persson | First 5 Authors: Casper W. Andersen, Rickard Armiento, Evgeny Blokhin, Gareth J. Conduit, Shyam Dwaraknath | Summary: The Open Databases Integration for Materials Design (OPTIMADE) consortium has designed a universal application programming interface (API) to make materials databases accessible and interoperable. We outline the first stable release of the […]

Formation of an extended stellar halo around an ultra-faint dwarf galaxy following one of the earliest mergers from galactic building blocks

Kavli Affiliate: Anna Frebel | First 5 Authors: Yuta Tarumi, Naoki Yoshida, Anna Frebel, , | Summary: Ultra-faint dwarf galaxies (UFDs) are promising observable proxies to building blocks of galaxies formed in the early Universe. We study the formation and evolution of UFDs using cosmological hydrodynamic simulations. In particular, we show that a major merger […]

Dynamical Evolution of Voids with Surrounding Gravitational Tidal Field

Kavli Affiliate: Naoshi Sugiyama | First 5 Authors: Mutsumi Minoguchi, Atsushi J. Nishizawa, Tsutomu T. Takeuchi, Naoshi Sugiyama, | Summary: The void ellipticity distribution today can be well explained by the tidal field. Going a step further from the overall distribution, we investigate individuality on the tidal response of void shape in non-linear dynamical evolution. […]

Scalable Hamiltonian learning for large-scale out-of-equilibrium quantum dynamics

Kavli Affiliate: Eliska Greplova | First 5 Authors: Agnes Valenti, Guliuxin Jin, Julian LĂ©onard, Sebastian D. Huber, Eliska Greplova | Summary: Large-scale quantum devices provide insights beyond the reach of classical simulations. However, for a reliable and verifiable quantum simulation, the building blocks of the quantum device require exquisite benchmarking. This benchmarking of large scale […]

Fermionization and boundary states in 1+1 dimensions

Kavli Affiliate: Yuji Tachikawa | First 5 Authors: Yoshiki Fukusumi, Yuji Tachikawa, Yunqin Zheng, , | Summary: In the last few years it was realized that every fermionic theory in 1+1 dimensions is a generalized Jordan-Wigner transform of a bosonic theory with a non-anomalous $mathbb{Z}_2$ symmetry. In this note we determine how the boundary states […]

Quantum Oscillations and the Quasiparticle Properties of Thin Film Sr$_2$RuO$_4$

Kavli Affiliate: Lena F. Kourkoutis | First 5 Authors: Yawen Fang, Hari P. Nair, Ludi Miao, Berit Goodge, Nathaniel J. Schreiber | Summary: We measure the Shubnikov-de Haas effect in thin-film Sr$_2$RuO$_4$ grown on an (LaAlO$_3$)$_{0.29}$-(SrAl$_{1/2}$Ta$_{1/2}$O$_3$)$_{0.71}$ (LSAT) substrate. We detect all three known Fermi surfaces and extract the Fermi surface volumes, cyclotron effective masses, and […]

Mutual Information Scaling for Tensor Network Machine Learning

Kavli Affiliate: Birgitta Whaley | First 5 Authors: Ian Convy, William Huggins, Haoran Liao, K. Birgitta Whaley, | Summary: Tensor networks have emerged as promising tools for machine learning, inspired by their widespread use as variational ansatze in quantum many-body physics. It is well known that the success of a given tensor network ansatz depends […]

PROBs and perverse sheaves I. Symmetric products

Kavli Affiliate: Mikhail Kapranov | First 5 Authors: Mikhail Kapranov, Vadim Schechtman, , , | Summary: Algebraic structures involving both multiplications and comultiplications (such as, e.g., bialgebras or Hopf algebras) can be encoded using PROPs (categories with PROducts and Permutations) of Adams and MacLane. To encode such structures on objects of a braided monoidal category, […]
