Mode‐dependent Far‐field Radiation of Circularly Polarized Light by a Single Plasmonic Nanohelix
Advanced Optical Materials, Volume 13, Issue 8, March 13, 2025.The numerical simulations explored the chiroptical response and far‐field radiation behaviors of single plasmonic nanoantennas transitioning into helical structures. This study highlights the ability of these plasmonic nanohelices to regulate the far‐field directionality of radiation power and circular polarization in plasmon‐exciton coupled systems ...

Solving the strong CP problem with massless grand-color quarks
Journal of High Energy PhysicsWe propose a solution to the strong CP problem that specifically relies on massless quarks and has no light axion. The QCD color group SU(3) c is embedded into a larger, simple gauge group (grand-color) where one of the massless, colored fermions enjoys ...

Advanced Optical Materials, EarlyView.For most microscopy measurements the sample is placed on a substrate, which causes symmetry breaking, especially relevant for chiral plasmonic nanostructures. DNA origami mediated X‐shaped AuNR dimers showing high structural purity in solution, exhibit significant diversity in lineshapes and signal intensities for their circular differential scattering

Asymmetric Transmission and Diffraction Engineering in Ultrathin media via Coupled Metasurfaces
Advanced Optical Materials, EarlyView.Grating‐insulator‐grating coupled crosstalking metasurfaces hosted on a silicon nitride membrane platform for asymmetric control of the diffraction pattern and asymmetric transmission. It is shown that exploiting the interferences of higher diffraction orders between the two metasurfaces and engineering the resulting modes enables AT in such ...

SciPost PhysicsWe study four-dimensional adjoint QCD with gauge group $SU(2)$ and two Weyl fermion flavors, which has an $SU(2)_R$ chiral symmetry. The infrared behavior of this theory is not firmly established. We explore candidate infrared phases by embedding adjoint

Spin‐Valley Polarization Control in WSe2 Monolayers using Photochemical Doping
Advanced Optical Materials, EarlyView.A photochemical doping method is employed to modulate the spin‐valley polarization in WSe2 monolayers by tuning the carrier density from electron‐rich to hole‐rich regimes. This controlled doping enables a three‐fold variation in exciton polarization, revealing relaxation channels driven by scattering between excitons and charge carriers in two ...

Advanced Optical Materials, EarlyView.Here, recent progress is highlighted in colloidal magnetoplasmonic hybrid nanomaterials, with a focus on chiral plasmonics. Metal nanocrystals with intrinsic chiroptical features can lead to a combination of chiral plasmonics and magneto‐optics effects when interacting with the magnetic counterpart, offering a foundation for systematically designing ...
