Circularly Polarized Polariton Lasing from Spin-Momentum Locking in Deformed Plasmonic Kagome Cavities. [PDF]
Adv MaterThis paper describes room‐temperature polariton lasing with high circular polarization from deformed plasmonic Kagome lattice cavities strongly coupled to colloidal CdSe nanoplatelets. Spin‐selectivity from cavity modes resulted in control over the handedness of circular polarization as well as the direction of polariton lasing, opening prospects for ...

Computing Least Fixed Points of Probabilistic Systems of Polynomials [PDF]
, 2010 We study systems of equations of the form X1 = f1(X1, ..., Xn), ..., Xn = fn(X1, ..., Xn), where each fi is a polynomial with nonnegative coefficients that add up to 1.

Room-Temperature Collective Quantum Emission Mediated by Wannier-Mott Excitons in CsPbBr<sub>3</sub> Nanowires. [PDF]
Small SciRoom‐temperature collective quantum emission emerges in partially aligned CsPbBr3 nanowires through spontaneous synchronization of Wannier–Mott excitons. This alignment enables cooperative dipole–dipole interactions that result in coherent photon bursts (N2 × hν), even under ambient conditions.

Nonhomogeneous Nonlinear Dirichlet Problems with a p-Superlinear Reaction
Abstract and Applied Analysis, 2012 We consider a nonlinear Dirichlet elliptic equation driven by a nonhomogeneous differential operator and with a Carathéodory reaction f(z,ζ), whose primitive f(z,ζ) is p-superlinear near ±∞, but need not satisfy the usual in such cases, the Ambrosetti ...

Positive solutions for nonparametric anisotropic singular solutions [PDF]
Opuscula MathematicaWe consider an elliptic equation driven by a nonlinear, nonhomogeneous differential operator with nonstandard growth. The reaction has the combined effects of a singular term and of a "superlinear" perturbation.

Multiple positive solutions to elliptic boundary blow-up problems [PDF]
, 2016 We prove the existence of multiple positive radial solutions to the sign-indefinite elliptic boundary blow-up problem \[ \left\{\begin{array}{ll} \Delta u + \bigl(a^+(\vert x \vert) - \mu a^-(\vert x \vert)\bigr) g(u) = 0, & \; \vert x \vert < 1, \\ u(x)

Local convergence of the Levenberg-Marquardt method under H\"{o}lder metric subregularity [PDF]
, 2019 We describe and analyse Levenberg-Marquardt methods for solving systems of nonlinear equations. More specifically, we propose an adaptive formula for the Levenberg-Marquardt parameter and analyse the local convergence of the method under H\"{o}lder ...

Mathematics, 2020 In this paper, we consider a nonlocal p(x)-Kirchhoff problem with a p+-superlinear subcritical Caratheodory reaction term, which does not satisfy the Ambrosetti–Rabinowitz condition.
