Konform geometria Riemann-Finsler típusú metrikus tereken = Conform geometry of spaces with Riemann-Finsler metrics

, 2010
Témánk az ún. Finsler-terek konform geometriája, különös tekintettel speciális tértípusok konform ekvivalenciájára. Egy sokaság Finsler-tér, ha az érintővektorok hosszát egy nem feltétlenül belső szorzatból származó funkcionálsereg segítségével mérni ...

The exact s-matrices of affine toda field theories [PDF]

, 1990
This thesis is concerned with exact solutions to various massive field theories in 1+1 dimensions.Two approaches are described. The first, abstract and non-lagrangian, relies on the considerable understanding that there now is of massless two-dimensional

Geometry of D_4 conformal triality and singularities of tangent surfaces [PDF]

, 2014
It is well known that the projective duality can be understood in the context of geometry of An-type. In this paper, as D4-geometry, we construct explicitly a flag manifold, its triplefibration and differential systems which have D4-symmetry and ...

High‐Index, Low‐Loss Optical Material Platforms for Ultra‐Broadband Ultraviolet‐to‐Visible Achromatic Metalenses

Advanced Functional Materials, EarlyView.
An integrated material platform combining engineered SiNx thin films and printable ZrO2 nanoparticle‐embedded resin enables broadband achromatic metalenses from the ultraviolet to visible range. The demonstrated meta‐optics achieve near‐diffraction‐limited focusing with minimal chromatic aberration.

Exciton Binding Energy of Phosphorescent Emitter Molecules in Organic Light‐Emitting Diodes

Advanced Functional Materials, EarlyView.
Energy level alignment is key to efficient OLED design, yet determining LUMO energies remains challenging. A methodology based on field‐induced dissociation and kinetic Monte Carlo simulations is presented to extract LUMO energies of iridium‐based phosphorescent emitters from their exciton binding energy.

Hyperelliptic families and 4d N = 2 $$ \mathcal{N}=2 $$ SCFT

Journal of High Energy Physics
We classify four dimensional N = 2 $$ \mathcal{N}=2 $$ SCFTs whose Seiberg-Witten (SW) geometries can be written as hyperelliptic families. By using special Kähler condition of SW geometry, we reduce the problem to one parameter quasi-homogeneous ...

Ab initio derivation of the quantum Dirac equation by conformal differential geometry: the "Affine Quantum Mechanics'"

, 2011
A rigorous \textit{ab initio} derivation of the (square of) Dirac's equation for a single particle with spin is presented. The general Hamilton-Jacobi equation for the particle expressed in terms of a background Weyl's conformal geometry is found to be linearized, exactly and in closed form, by an \textit{ansatz} solution that can be straightforwardly ...

Swelling‐Induced Stress‐Assisted Transfer of Nanodiamond Arrays With a PVA Carrier Tape for Conformal Bio‐Integrated Sensing and Labelling

Advanced Functional Materials, EarlyView.
This work introduces a swelling‐induced, stress‐assisted water‐soluble PVA tape strategy to transfer‐print nanodiamond quantum‐sensor arrays onto soft, curved biological interfaces. The room‐temperature, water‐triggered process achieves >98% fidelity and residue‐free integration, enabling conformal quantum sensing on contact lenses, neural probes, and ...

Ionic Transportation Induced Electric Field Modulation in Porous Ecoflex/PTFE with Confined Liquid for High‐Performance Contact Electrification Power Generation

Advanced Functional Materials, EarlyView.
Porous Ecoflex/PTFE composite with encapsulated liquid generates electricity through ionic migration induced by dynamic pore deformation, creating non‐uniform electric fields that drive charge induction on electrodes. This mechanism enhances charge transfer and ensures stable contact electrification performance, achieving 12 V and 4 nC with consistent ...
