Projections, the Weighted Bergman Spaces, and the Bloch Space [PDF]
Proceedings of the American Mathematical Society, 1990 The author extends some results of \textit{F. Forelli} and \textit{W. Rudin} [Indiana Univ. Math. J. 24, 593-602 (1974; Zbl 0297.47041)] and \textit{K. Zhu} [J. Funct. Anal. 81, No.2, 260-278 (1988; Zbl 0669.47019)]. Let B be the unit ball in \({\mathbb{C}}^ n\). H(B) denotes the class of holomorphic functions on B.

Quasi‐Single‐Mode Polaritonic Crystal for Hyperbolic Phonon‐Polaritons
Advanced Optical Materials, EarlyView.Near‐field study of the polaritonic Fourier crystal with α‐MoO3 reveals that the hyperbolic phonon‐polaritons within the Type‐I Reststrahlen band may form a quasi‐single‐mode Bloch wave where only the fundamental mode propagates in the crystal. Our results demonstrate the realization of a quasi‐single‐mode regime for the inherently multimode hyperbolic

Cross‐Phase Modulation via Time‐Varying Epsilon‐Near‐Zero Metasurfaces
Advanced Optical Materials, EarlyView.Time‐varying epsilon‐near‐zero metasurfaces are shown to enable cross‐phase modulation beyond conventional ENZ excitation. By engineering dual absorption bands and exploiting oblique ultrafast pumping, large and broadband frequency translations are achieved at low pump energies.

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 ...

Photonics of Topological Magnetic Textures
Advanced Optical Materials, EarlyView.Localized noncollinear magetic textures imprint their geometry and topology onto traversing photonic fields endowing them with orbital angular‐momentum, chirality, and magnetoelectric densities. Abstract Topological textures in magnetically ordered materials are an important case studies for fundamental research with promising applications in data ...

Abstract and Applied Analysis, 2010 Operator norm and essential norm of an integral-type operator, recently introduced by this author, from the Dirichlet space to the Bloch-type space on the unit ball in ℂ𝑛 are calculated here.

Journal of Inequalities and Applications, 2016 In this paper, we give some estimates of the essential norm for generalized weighted composition operators from the Bloch space to the Zygmund space. Moreover, we give a new characterization for the boundedness and compactness of the operator.

Advanced Science, EarlyView.Thermal transport in smooth‐interface superlattices is studied using the phonon Wigner transport equation, which captures both particle‐like and wave‐like contributions. A minimum in cross‐plane thermal conductivity emerges with increasing period thickness, signaling a crossover from coherent to incoherent phonon transport.

Advanced Science, EarlyView.Photonic time crystals (PTCs) are systems in which electromagnetic parameters are modulated periodically in time, producing momentum bandgaps via temporal scattering rather than spatial Bragg processes. This review examines the theoretical frameworks, modeling, and computational tools for time‐varying media, and summarizes experimental demonstrations ...
