Strong traces for degenerate parabolic-hyperbolic equations and applications [PDF]
, 2007 textWe consider bounded weak solutions u of a degenerate parabolic-hyperbolic equation defined in a subset [mathematical symbols]. We define strong notion of trace at the boundary [mathematical symbols] reached by L¹ convergence for a large class of ...

On quasilinear hyperbolic equations with degenerate principal part
Tsukuba Journal of Mathematics, 1998 The goal of the present paper is to study the quasilinear weakly hyperbolic Cauchy problem \[ u_{tt}= \sum_{i,j} (a_{ij}(t,x)u_{x_i})_{x_j}+ f(t,x,u,\nabla_x u), \] \[ u(0,x)= u_0(x),\quad u_t(0,x)= u_1(x). \] Here weakly hyperbolic means \[ 0\leq \sum^n_{i,j= 1} a_{ij}(t,x)\xi_j \xi_j\leq \Lambda|\xi|^2.

Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics
Advanced Materials, EarlyView.The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and

Directional Flow of Confined Polaritons in CrSBr
Advanced Materials, EarlyView.CrSBr, a layered magnetic semiconductor, naturally channels self‐hybridized excitonpolaritons into highly directional flow. Its intrinsic optical anisotropy, high refractive index, and strong lightmatter coupling enable long‐range guided modes along the a‐axis, with propagation lengths set by their excitonphoton admixture.

Tailoring Phonon‐Driven Responses in α‐MoO3 through Isotopic Enrichment
Advanced Materials, EarlyView.ABSTRACT The implementation of polaritonic materials into nanoscale devices requires selective tuning of parameters to realize desired spectral or thermal responses. One robust material, α‐MoO3, an orthorhombic crystal boasting three distinct phonon dispersions, provides three polaritonic dispersions of hyperbolic phonon polaritons (HPhPs) across the ...
