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 […]

Topological active matter

Kavli Affiliate: Mark J. Bowick | First 5 Authors: Suraj Shankar, Anton Souslov, Mark J. Bowick, M. Cristina Marchetti, Vincenzo Vitelli | Summary: Active matter encompasses different nonequilibrium systems in which individual constituents convert energy into non-conservative forces or motion at the microscale. This review provides an elementary introduction to the role of topology in […]

Heterobilayer moiré magnets: moiré skyrmions and the commensurate-incommensurate transition

Kavli Affiliate: Leon Balents | First 5 Authors: Kasra Hejazi, Zhu-Xi Luo, Leon Balents, , | Summary: We study untwisted heterobilayers of ferromagnetic and antiferromagnetic van der Waals materials, with in particular a Dzyaloshinskii-Moriya interaction in the ferromagnetic layer. A continuum low energy field theory is utilized to study such systems. We develop a phase […]
