Connectedness and Contractibility of Solutions in Set Optimization Under Set Less Order Relations

Journal of Mathematics
This study establishes the topological properties of solution sets in set optimization, focusing on their connectedness and contractibility. Utilizing the arcwise convexity and lower semicontinuity characteristics derived from scalarization techniques ...

Spontaneous scalarization in Einstein-power-Maxwell-scalar models

Physics of the Dark Universe
We study the spontaneous scalarization of charged black holes in Einstein's gravity minimally coupled to power--Maxwell electrodynamics which, in turn, is non--minimally coupled to a real scalar field. We point out the existence of a specific power for which the scalarized solution is well-behaved, and entropically preferred in comparison to the scalar-

Two‐Dimensional Isotropic Spatial Differentiation Through Complete Polarization Control

Advanced Optical Materials, EarlyView.
This work enables two‐dimensional isotropic spatial differentiation at planar interfaces over a wide range of incident angles by extending the output polarization from linear to elliptical. The choice of incident angle can be used to balance broader spectral response at low angles and higher edge‐detection efficiency at larger angles.

Topological aspects in vector optimization problems

Vìsnik Dnìpropetrovsʹkogo Unìversitetu: Serìâ Modelûvannâ, 2009
In this paper, we study vector optimization problems in partially ordered Banach spaces. We suppose that an objective mapping possesses a weakened property of lower semicontinuity and make no assumptions on the interior of the ordering cone.

Pointlike Material Accumulation and Displacement in Azopolymer Thin Films Driven by Spatial Light Modulation

Advanced Optical Materials, EarlyView.
A maskless, SLM‐driven approach enables the deterministic inscription of arbitrary topographical features in azopolymer films by mapping complex vectorial light fields onto local viscoplastic stress. This platform allows for the rapid generation and dynamic erasure of high‐aspect‐ratio micro‐spikes, offering a versatile tool for reconfigurable flat ...

Multiple Scattering Model for the Coherent Optical Response of Correlated Disordered Plasmonic Metasurfaces

Advanced Optical Materials, EarlyView.
Disordered plasmonic metasurfaces enable advanced control over light scattering through disorder engineering. A theoretical model based on multiple scattering theory is developed to predict the coherent reflection and transmission of light from disordered metasurfaces with arbitrary pair correlations.

Quantum parameter-mass induced scalarization of qOS-black hole in the Einstein–Gauss–Bonnet-scalar theory

European Physical Journal C: Particles and Fields
We obtain quantum parameter ( $$\alpha $$ α )-mass (M) induced spontaneous scalarization of quantum Oppenheimer–Snyder (qOS)-black hole in the Einstein–Gauss–Bonnet-scalar theory with the unknown qOS action.

Reconciling spontaneous scalarization with cosmology

, 2019
International audienceWe discuss the Damour–Esposito-Farèse model of gravity, which predicts the spontaneous scalarization of neutron stars in a certain range of parameter space.

Massively Degenerate Coherent Perfect Absorption in Gradient‐Index Fibers

Advanced Optical Materials, EarlyView.
A coherent perfect absorber (CPA) normally operates for only one or very few spatial modes. The CPA proposed here uses a gradient‐index (GRIN) fiber to absorb hundreds of spatial modes at once, its self‐imaging property replacing the bulky free‐space degenerate cavity of earlier designs. An analytic criterion sets how much modal degeneracy is required,
