Advanced Functional Materials, EarlyView.Here, we develop a high‐throughput algorithm that accelerates the elucidation of phase diagrams of topological spin textures using limited computational resources at high numerical accuracy. Applying this framework to the van der Waals magnet CrSBr, we unveiled a hierarchy of previously unknown topological textures (domain‐wall bimerons, bimeron chains,

Dirac Semimetallicity Enabled by Stripe Antiferromagnetism in Monolayer FeSe
Advanced Functional Materials, EarlyView.In monolayer FeSe, stripe antiferromagnetic order selectively breaks mirror symmetry, enabling odd inter‐orbital hybridization between opposite‐parity Fe 3d states. This mechanism stabilizes symmetry‐protected Dirac nodes with nontrivial Wilson‐loop topology and edge states, accompanied by a strong orbital diamagnetic susceptibility as an experimental ...

Advanced Materials, EarlyView.A Nb‐proximitized Josephson junction based on a WTe2/α‐Fe2O3 heterostructure exhibits a robust superconducting diode effect with programmable polarity. The diode direction can be trained by magnetic fields and switched by temperature cycling, revealing tunable finite‐momentum pairing states and competing superconducting states in symmetry‐broken ...

Some notes on port-Hamiltonian systems on Banach spaces [PDF]
, 2021 We consider port-Hamiltonian systems from a functional analytic perspective. Dirac structures and Hamiltonians on Banach spaces are introduced, and an energy balance is proven.

Advanced Materials, EarlyView.The energetic offset between the donor and the acceptor components in organic photoactive layers is central to the tradeoff between photovoltage and photocurrent losses. This Perspective covers the most important issues surrounding this topic in non‐fullerene acceptor blends, from the difficulty of accurately determining state energies and driving ...

On the algebraic properties of difference approximations of Hamiltonian systems
Discrete and Continuous Models and Applied Computational ScienceIn this paper, we examine difference approximations for dynamic systems characterized by polynomial Hamiltonians, specifically focusing on cases where these approximations establish birational correspondences between the initial and final states of the ...
