Anisotropic superconducting spin transport at magnetic interfaces

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 […]

CharacterGAN: Few-Shot Keypoint Character Animation and Reposing

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 […]

Certifying Numerical Decompositions of Compact Group Representations

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 […]

Floquet chiral hinge modes and their interplay with Weyl physics in a three-dimensional lattice

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 […]

Local Operator Entanglement in Spin Chains

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 […]

XraySyn: Realistic View Synthesis From a Single Radiograph Through CT Priors

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 […]

The axiomatic and the operational approaches to resource theories of magic do not coincide

Kavli Affiliate: David Gross | First 5 Authors: Arne Heimendahl, Markus Heinrich, David Gross, , | Summary: Stabiliser operations occupy a prominent role in fault-tolerant quantum computing. They are defined operationally: by the use of Clifford gates, Pauli measurements and classical control. These operations can be efficiently simulated on a classical computer, a result which […]

Fluctuations can induce local nematic order and extensile stress in monolayers of motile cells

Kavli Affiliate: Boris I. Shraiman | First 5 Authors: Farzan Vafa, Mark J. Bowick, Boris I. Shraiman, M. Cristina Marchetti, | Summary: Recent experiments in various cell types have shown that two-dimensional tissues often display local nematic order, with evidence of extensile stresses manifest in the dynamics of topological defects. Using a mesoscopic model where […]

P-orbital magnetic topological states on square lattice

Kavli Affiliate: Bo Gu | First 5 Authors: Jing-Yang You, Bo Gu, Gang Su, , | Summary: Honeycomb or triangular lattices were extensively studied and thought to be proper platforms for realizing quantum anomalous Hall effect (QAHE), where magnetism is usually caused by d orbitals of transition metals. Here we propose that square lattice can […]

One-dimensional model for deconfined criticality with $mathbb{Z}_3 times mathbb{Z}_3$ symmetry

Kavli Affiliate: Shenghan Jiang | First 5 Authors: Brenden Roberts, Shenghan Jiang, Olexei I. Motrunich, , | Summary: We continue recent efforts to discover examples of deconfined quantum criticality in one-dimensional models. In this work we investigate the transition between a $mathbb{Z}_3$ ferromagnet and a phase with valence bond solid (VBS) order in a spin […]
