Advanced Functional Materials, EarlyView.Symmetry‐broken plasmonic nanoantenna arrays achieve broadband multiresonant enhancement of second harmonic generation (SHG), third harmonic generation (THG), and upconversion photoluminescence (UCPL), under femtosecond laser excitation across the near‐infrared range (1000–1600 nm).

Critical exponents: old and new
The Electronic Journal of Linear Algebra, 2012 For Hadamard and conventional powering, we survey past and current work on the existence and values of critical exponents (CEs) for such matrix classes as doubly nonnegative, totally positive, M- and inverse M-matrices. There are remarkable similarities and differences between Hadamard and conventional CEs for the various classes. real t if appropriate)

Advanced Functional Materials, EarlyView.Phosphorescent OLEDs suffer from efficiency roll‐off due to triplet‐polaron quenching (TPQ). This study demonstrates for a large set of host‐guest combinations a spectroelectrochemical method to measure the absorption of charged molecules, enabling determining TPQ Förster radii (2.5–4 nm) from the spectral overlap.

Advanced Functional Materials, EarlyView.The THz drive of the Mott insulating state of a rare‐earth nickelate induces instantaneous insulator‐metal transition via quantum tunneling of valence electrons across the bandgap. This transition is pure electronic and highly non‐thermal, which may find its applications in ultrafast opto‐electronics with enhanced performance and minimal device size ...

On elliptic equations in RN with critical exponents
Electronic Journal of Differential Equations, 1996 Principle and the Mountain Pass Theorem-- to study the equation $$-Delta u + a(x)u = lambda u^q + u^{2^*-1} quad{ m in } R^N,.$$ The main concern is overcoming compactness difficulties due both to the unboundedness of the domain $R^N$, and the presence ...

Geometrical interpretation of critical exponents
Physical Review EWe develop the hypothesis that the dynamics of a given system may lead to the activity being constricted to a subset of space, characterized by a fractal dimension smaller than the space dimension. We also address how the response function might be sensitive to this change in dimensionality.
