Confined Hot Carrier Cooling Via Excited‐State Energy Gap Engineering in Graphyne Carbon Allotropes
ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.The excited‐state energy gap (EEG), regulated by the concentration of sp‐hybridized carbon, provides an effective handle for tuning electron–phonon coupling behavior. This design enables long‐lived confinement of hot carriers near the top of the EEG with controllable energy levels.

Weighted Composition Operators from Hardy Spaces into Logarithmic Bloch Spaces
Journal of Function Spaces and Applications, 2012 The logarithmic Bloch space Blog is the Banach space of analytic functions on the open unit disk 𝔻 whose elements f satisfy the condition ∥f∥=supz∈𝔻(1-|z|2)log (2/(1-|z|2))|f'(z)|

Revealing the Resonant Physics of Open Photonic Time Crystals
Laser &Photonics Reviews, EarlyView.ABSTRACT Photonic time crystals (PTCs) are media whose permittivity is modulated periodically in time, enabling momentum bandgaps and parametric amplification of light. Their realization at the nanoscale can revolutionize the study of light‐matter interactions.

Theory of Supercritical Coupling and Generalized Bound States in the Continuum
Laser &Photonics Reviews, EarlyView.We develop a general theory of supercritical coupling and generalized bound states in the continuum (gBICs), revealing how interference between radiative and absorptive channels enables quality factors beyond conventional material‐loss limits. The framework unifies non‐Hermitian mode coupling, causality‐driven reactive interactions, and interference ...

Bounded Frequency Lattices in Coupled Lithium Niobate Ring Cavities
Laser &Photonics Reviews, EarlyView.We leverage coupled asymmetric ring resonators in realizing bounded tight‐binding frequency lattices and demonstrate their discrete band structures on an integrated device. Suppression of long‐range coupling with a single auxiliary cavity is demonstrated by combining mode splitting and coupled waveguide dispersion effects.

ON TRACES OF ANALYTIC HERZ AND BLOCH TYPE SPACES IN BOUNDED STRONGLY PSEUDOCONVEX DOMAINS IN C^N
Проблемы анализа, 2014 In our paper we provide some direct extentions of our recent sharp results on traces in the analytic function spaces, which we proved earlier in case of the unit ball in C^n, to the case of the bounded strongly pseudoconvex domains with a smooth boundary.

From Planar to 3D Nanophotonic Lenses: Advancing Design, Fabrication, and Applications
Laser &Photonics Reviews, EarlyView.Three‐dimensional nanophotonic lenses are enabled by an integrated workflow that links design parameterization, full‐wave electromagnetic simulation, computational optimization, and freeform fabrication. This Review summarizes how these tools expand optical design freedom beyond a single patterned plane by enriching the local meta‐atom response and ...

Composition operator on Bloch type spaces
Analysis, 2003 Let \(D\) be the unit disk of the complex plane and let \(C_\varphi\) be the composition operator induced by a holomorphic self-map \(\varphi\) of \(D\). The author introduces the so-called Bloch type spaces and characterizes boundedness and compactness of a composition operator \(C_\varphi\) acting between various combinations of such Bloch type ...
