A Hofer-Type Norm of Hamiltonian Maps on Regular Poisson Manifold

Journal of Applied Mathematics, 2014
We define a Hofer-type norm for the Hamiltonian map on regular Poisson manifold and prove that it is nondegenerate. We show that the L1,∞-norm and the L∞-norm coincide for the Hamiltonian map on closed regular Poisson manifold and give some sufficient ...

Spontaneous Strain‐Spin Transition Coupling Molecular Crystal with Thermal Magnetic Memory Effect, Anisotropic High‐κ and Switchable Dielectric Permittivity

Advanced Science, EarlyView.
A radical salt undergoes a paraelastic‐ferroelastic phase transition, which is coupled with spin‐Peierls transition, resulting in it integrating self‐strain, spin bistability, switchable dielectric and high‐ properties. Abstract Materials that exhibit controllable changes in electrical, magnetic, or spontaneous strain properties, particularly those ...

Imprinting Electrically Switchable Scalar Spin Chirality by Anisotropic Strain in a Kagome Antiferromagnet

Advanced Science, EarlyView.
It is shown that anisotropic strain offers a novel approach to control the magnetic ground state in heterostructures of a Kagome antiferromagnet, unlocking new functionalities. This strain induces finite scalar spin chirality, resulting in a pronounced Berry curvature in momentum space, leading to room‐temperature anomalous Hall effect.

Protected Chaos in a Topological Lattice

Advanced Science, EarlyView.
Topological and chaotic dynamics are often considered incompatible, with one expected to dominate or disrupt the other. This work reveals that topological localization can persist even under strong chaotic dynamics and, counter‐intuitively, protect chaotic behavior.

Designing Spin Symmetry for Altermagnetism with Strong Magnetoelectric Coupling

Advanced Science, EarlyView.
Antiferromagnets can be induced into altermagnets by changing the real‐space symmetry, increasing their potential for use in spintronic devices. Here, a novel and general approach is proposed: transforming antiferromagnets into altermagnets by modulating spin‐space symmetry, rather than real‐space symmetry.

Packaging Metal Atomic Clusters for Universal and Robust Protection through Cluster Beam Process

Advanced Science, EarlyView.
Gas‐phase‐aggregated metal clusters are packaged and well‐protected in poly(methyl methacrylate) (PMMA) through controlled beam implantation. The packaged precise clusters show robust protection against oxidation and agglomeration. This protection also demonstrates universality, as it successfully protects metal clusters composed of various elements ...
