Skyrmionic Polarization Textures in Structured Dielectric Planar Media. [PDF]

Nanophotonics
Topological skyrmionic textures are typically associated with the structure of optical fields. This work demonstrates that they can also emerge from the optical response of structured metasurfaces. Through engineered light–matter interaction, polarization eigenstates acquire nontrivial topology, which can be mapped into the Chern‐insulator physics ...

The role of patient reported symptom data in co-producing meaning in rheumatoid arthritis. [PDF]

J Eval Clin Pract
Abstract Rationale Patients with rheumatoid arthritis (RA) experience a range of symptoms including joint pain and inflammation, stiffness, fatigue, anxiety, and low mood. Similar to patients with other long‐term conditions, they may have periods of time when their disease is under control, and times when their condition is less stable, requiring ...

Vortex beam nanofocusing and optical skyrmion generation via hyperbolic metamaterials. [PDF]

Nanophotonics
Abstract While spin angular momentum is limited to ±ℏ, orbital angular momentum (OAM) is, in principle, unbounded, enabling tailored optical transition rules in quantum systems. However, the large optical size of vortex beams hinders their coupling to nanoscale platforms such as quantum emitters. To address this challenge, we experimentally demonstrate

Deep-subwavelength resolution detection of polar magnetization by optical spin meron lattices on hyperbolic metamaterials. [PDF]

Nanophotonics
Abstract Magnetic‐optical Kerr or Faraday effects have been widely used to measure magnetic domain structures by analyzing far‐field polarization properties, with resolution limited by the wavelength scale of light. Here, we propose a methodology to measure the magnetic domain at a deep‐subwavelength scale by investigating the interactions between a ...

Photonuclear Population of ^229m,gTh in Th-Doped Crystals Toward Nuclear Clock Development. [PDF]

Adv Sci (Weinh)
This study demonstrates a novel photonuclear approach for producing the nuclear clock isomer 229mTh in thorium‐doped crystals, overcoming current supply limitations. Through cross‐section calculations and Monte Carlo simulations, we identify optimal crystal materials and irradiation conditions, achieving high signal‐to‐noise ratios.

From dark modes to topology: light-induced skyrmion generation in a plasmonic nanostructure through the inverse faraday effect. [PDF]

Nanophotonics
Abstract Skyrmions are topological structures characterized by a winding vectorial configuration that provides a quantized topological charge. In magnetic materials, skyrmions are localized spin textures that exhibit unique stability and mobility properties, making them highly relevant to the burgeoning field of spintronics. In optics, these structures

On the robustness of solitons crystals in the Skyrme model

Nuclear Physics B, 2022
In this work we analize how the inclusion of extra mesonic degrees of freedom affect the finite density solitons crystals of the Skyrme model. In particular, the first analytic examples of hadronic crystals at finite baryon density in both the Skyrme ω ...

Electroexcitation Form Factors and Deformation of 20,22Ne Isotopes Based on the Shell Model and Hartree-Fock plus BCS Calculations

East European Journal of Physics, 2023
Nuclear structure of 20,22Ne isotopes has been studied via the shell model with Skyrme-Hartree-Fock calculations. In particular, the transitions to the low-lying positive and negative parity excited states have been investigated within three shell model
