Transverse Square Toroidal Vortices with Giant Ferrotoroidic Coupling in Dy‐Bridged Single‐Molecule Toroics

European Journal of Inorganic Chemistry, Volume 29, Issue 9, 20 March 2026.
Single‐molecular toroics (SMTs) offer protected magnetic states for next‐generation quantum technologies. Ab initio and model analyses of Cu2Dy7 and Cu4Dy12 reveal unconventional excited states featuring delocalised toroidal moments that couple into strong ferro‐ and antiferrotoroidic configurations, providing unprecedented magnetic coupling within ...

Quantum simulation of non-Abelian lattice gauge theories: A variational approach to D_{8} with dynamical matter

Physical Review Research
Quantum simulation of lattice gauge theories (LGTs) provides a powerful framework for understanding nonperturbative phenomena. However, to realize the hope of answering challenging physics questions on near-term devices it is crucial to develop resource ...

Renormalization for cubic frequency invariant tori in Hamiltonian systems with two degrees of freedom

Discrete and Continuous Dynamical Systems - Series B, 2002
We consider the break-up of invariant tori in Hamiltonian systems with two degrees of freedom with a frequency which belongs to a cubic field. We define and construct renormalization-group transformations in order to determine the threshold of the break-up of these tori.

Stable Model Reduction for Time‐Domain Room Acoustics: A Structure‐Preserving Formulation for Complex Boundaries

International Journal for Numerical Methods in Engineering, Volume 127, Issue 5, 15 March 2026.
ABSTRACT This work presents novel structure‐preserving formulations for stable model order reduction in the context of time‐domain room acoustics simulations. A solution to address the instability in conventional model order reduction formulations based on the Linearized Euler Equations is derived and validated through numerical experiments.

Single Pair of Weyl Points Evolve From Spin Group‐Protected Nodal Line in Half‐Metallic Ferromagnet V3S4

Advanced Functional Materials, Volume 36, Issue 21, 12 March 2026.
A spin group (SG)‐based mechanism is proposed to realize a single pair of Weyl points. PT‐symmetric nodal lines (NLs) persist under T‐breaking, protected by the combination of SG and P symmetry. When considering spin‐orbit coupling, the SG‐protected NL will split into Weyl points, which will also induce anomalous transport phenomena arising from ...

Kovacs-like memory effect in dense liquids of responsive colloids

New Journal of Physics
Responsive colloids (RCs) exhibit a rich non-equilibrium behavior due to the interplay between translational motion and the dynamics of internal degrees of freedom (DoFs), such as the particle size.

Low‐Symmetry Weyl Semimetals: A Path to Ideal Topological States

Advanced Functional Materials, Volume 36, Issue 21, 12 March 2026.
This study presents a theoretical framework for realizing ideal Weyl semimetals, where Weyl nodes are well‐isolated at the Fermi level. The approach is exemplified in the low‐symmetry material Cu2SnSe3, which exhibits tunable topological phases, current‐induced orbital magnetization, and a strong circular photogalvanic effect, making it a promising ...

Proximity Induced Magnetic Anisotropy and Trefoil Fermiology in Monolayer FeCl2/Bi(111)

Advanced Materials, Volume 38, Issue 16, 17 March 2026.
Reorientation of magnetic anisotropy in a 2D van der Waals magnet is demonstrated in monolayer FeCl2 epitaxially grown on a bismuth substrate, from its natural out‐of‐plane direction to a predominantly in‐plane orientation. The FeCl2/bismuth heterostructure exhibits moiré‐induced interface states, suggesting strong coupling at the interface.
