Coherent Spin Waves in Curved Ferromagnetic Nanocaps of a 3D‐Printed Magnonic Crystal

open access: yesSmall, Volume 22, Issue 7, 2 February 2026.
A nanoprinted 3D magnonic woodpile crystal is measured by microresonator ferromagnetic resonance. Micromagnetic simulations are performed to analyze and visualize the detected coherent spin‐wave modes along the nickel‐coated tubes and caps for various field angles. The woodpile exhibits an unexpected phase evolution and robust edge modes.

On Multilevel Energy‐Based Fragmentation Methods

open access: yesInternational Journal of Quantum Chemistry, Volume 126, Issue 3, January 30, 2026.
We investigate the working equations of energy‐based fragmentation methods and present ML‐SUPANOVA, a Möbius‐inversion‐based multilevel fragmentation scheme that enables adaptive, quasi‐optimal truncations to efficiently approximate Born‐Oppenheimer potentials across hierarchies of electronic‐structure methods and basis sets.

Generalized Surface Conductivity Model for Anisotropic Phonon Polaritons in van der Waals Slabs

open access: yesNanophotonics, Volume 15, Issue 2, 27 January 2026.
Herein, we report a generalized surface conductivity model which includes all waveguide polariton branches, by taking into account the out‐of‐plane dimension. Using this generalized 2D model can separate and examine each individual polaritonic mode in van der Waals slabs and further clarify their contributions in near‐field light matter interactions ...

Full Asymmetric Radiation Control Through Multi‐Channel Bound States in the Continuum

open access: yesNanophotonics, Volume 15, Issue 2, 27 January 2026.
Bound states in the continuum (BICs) enable extreme light confinement via high Q‐factors, but their radiation splits into half‐spaces with limited beam control. Here, in super wavelength BICs (supporting multiple diffraction orders), we design co‐propagating orders in one half‐space, achieving full tuning of UGRs’ directionality (−1 to 1) and phase (‐π

Fabrication‐Directed Entanglement for Designing Chiral and Anisotropic Metamaterial Foams

open access: yesAdvanced Engineering Materials, Volume 28, Issue 2, January 21, 2026.
This work introduces fabrication‐directed entanglement (FDE), combining viscous thread printing and topology optimization to program entangled foams with spatially patterned stiffness. By tuning coil density, FDE enables anisotropy, programmable Poisson's ratio, and chirality in foams.
