Kavli Affiliate: Mark J. Bowick | First 5 Authors: Zhitao Chen, Duanduan Wan, Mark J. Bowick, , | Summary: Very thin elastic sheets, even at zero temperature, exhibit nonlinear elastic response by virtue of their dominant bending modes. Their behavior is even richer at finite temperature. Here we use molecular dynamics (MD) to study the […]
Kavli Affiliate: Leon Balents | First 5 Authors: Takamori Park, Mengxing Ye, Leon Balents, , | Summary: We study electronic instabilities of a kagome metal with a Fermi energy close to saddle points at the hexagonal Brillouin zone face centers. Using parquet renormalization group, we determine the leading and subleading instabilities, finding superconducting, charge, orbital […]
Kavli Affiliate: David J. Gross | First 5 Authors: David J. Gross, Vladimir Rosenhaus, , , | Summary: Motivated by the desire to understand chaos in the $S$-matrix of string theory, we study tree level scattering amplitudes involving highly excited strings. While the amplitudes for scattering of light strings have been a hallmark of string […]
Kavli Affiliate: Biao Huang | First 5 Authors: Yitao Yan, Jie Bao, Biao Huang, , | Summary: This paper formulates a framework for the analysis and distributed control of interconnected systems from the behavioural perspective. The discussions are carried out from the viewpoint of set theory and the results are completely representation-free. The core of […]
Kavli Affiliate: Mamoru Matsuo | First 5 Authors: Yuya Ominato, Ai Yamakage, Mamoru Matsuo, , | Summary: We present a theoretical investigation of anisotropic superconducting spin transport at a magnetic interface between a p-wave superconductor and a ferromagnetic insulator. Our formulation describes the ferromagnetic resonance modulations due to spin current generation depending on spin-triplet Cooper […]
Kavli Affiliate: Matthew Fisher | First 5 Authors: Tobias Hinz, Matthew Fisher, Oliver Wang, Eli Shechtman, Stefan Wermter | Summary: We introduce CharacterGAN, a generative model that can be trained on only a few samples (8 – 15) of a given character. Our model generates novel poses based on keypoint locations, which can be modified […]
Kavli Affiliate: David Gross | First 5 Authors: Felipe Montealegre-Mora, Denis Rosset, Jean-Daniel Bancal, David Gross, | Summary: We present a performant and rigorous algorithm for certifying that a matrix is close to being a projection onto an irreducible subspace of a given group representation. This addresses a problem arising when one seeks solutions to […]
Kavli Affiliate: Biao Huang | First 5 Authors: Biao Huang, Viktor Novičenko, André Eckardt, Gediminas Juzeliūnas, | Summary: We demonstrate that a three dimensional time-periodically driven (Floquet) lattice can exhibit chiral hinge states and describe their interplay with Weyl physics. A peculiar type of the hinge states are enforced by the repeated boundary reflections with […]
Kavli Affiliate: Masahiro Nozaki | First 5 Authors: Eric Mascot, Masahiro Nozaki, Masaki Tezuka, , | Summary: Understanding how and whether local perturbations can affect the entire quantum system is a fundamental step in understanding non-equilibrium phenomena such as thermalization. This knowledge of non-equilibrium phenomena is applicable for quantum computation, as many quantum computers employ […]
Kavli Affiliate: Cheng Peng | First 5 Authors: Cheng Peng, Haofu Liao, Gina Wong, Jiebo Luo, Shaohua Kevin Zhou | Summary: A radiograph visualizes the internal anatomy of a patient through the use of X-ray, which projects 3D information onto a 2D plane. Hence, radiograph analysis naturally requires physicians to relate the prior about 3D […]
