Topological Quasiparticles of Light: From Spin‐Orbit Coupling to Photonic Skyrmions
This review summarizes recent advances in photonic skyrmions, emphasizing the central role of spin–orbit coupling in their formation. The review discusses how spin–orbit interactions generate skyrmionic textures, examines modulation strategies for their dynamic control, and provides an overview of emerging directions and opportunities where these ...

Strong WW scattering chiral lagrangians, unitarity and resonances [PDF]
Chiral lagrangians provide a model independent description of the strongly interacting symmetry breaking sector. In this work, first we review the LHC sensitivity to the chiral parameters (in the hardest case of non-resonant low-energy WW scattering ...

We demonstrate that dispersion theory allows one to deduce crucial information on πη scattering from the final-state interactions of the light mesons visible in the spectral distributions of the decays B ¯ d 0 → J / ψ π 0 η , K + K − , K 0 K ¯ 0 ...

On 1D, N $$ \mathcal{N} $$ = 4 supersymmetric SYK-type models. Part I
Proposals are made to describe 1D, N $$ \mathcal{N} $$ = 4 supersymmetrical systems that ex- tend SYK models by compactifying from 4D, N $$ \mathcal{N} $$ = 1 supersymmetric Lagrangians involving chiral, vector, and tensor supermultiplets.

Effective Lagrangians and chiral random matrix theory [PDF]
Recently, sum rules were derived for the inverse eigenvalues of the Dirac operator. They were obtained in two different ways: i) starting from the low-energy effective Lagrangian and ii) starting from a random matrix theory with the symmetries of the Dirac operator. This suggests that the effective theory can be obtained directly from the random matrix

Magnetic Hopfions as Local Rotations of the Uniform Magnetization Background
The Hopf mapping of 3D coordinate space to the unit sphere m2 = 1 in the magnetization space m(r) can be parametrized by some angles. These angles are used to define a local rotation matrix to restore the hopfion magnetization configuration from the uniformly magnetized state for any Hopf indices.

Decays τ → ππηντ and τ → πηηντ in the extended Nambu–Jona-Lasinio model
In the framework of the extended Nambu–Jona-Lasinio model, the processes τ → ππη(η′)ντ and τ → πηη(η′)ντ are considered taking into account mesons in the ground and first radially excited intermediate states. It is shown that in the processes τ → ππη(η′)

This review comprehensively explores the structural configurations, properties, and applications of graphene variants—including monolayer, multilayer, and functionalized forms (graphene oxide, rGO, composites). It discusses fabrication techniques (mechanical exfoliation, chemical vapor deposition, epitaxy) and advanced mechanical characterization ...
