Holography for Cosmology [PDF]
, 2010 We propose a holographic description of four-dimensional single-scalar inflationary universes, and show how cosmological observables, such as the primordial power spectrum, are encoded in the correlation functions of a three-dimensional QFT.

Journal of Mathematical Analysis and Applications, 1980 AbstractThe problem that is presented and investigated is a natural nonlinear extension of the following linear problem. Let H ⊕ H′ and K ⊕ K′ be two orthogonal Hilbert decompositions of a real Hilbert space X. Let P, P′, Q, Q′ and N′ be the operators of orthogonal projection of X onto H, H′, K, K′ and H′ ∩ K′ respectively.

Switchable Thermal Mid‐IR Conducting Polymer Antenna Arrays
Advanced Functional Materials, EarlyView.This study presents switchable mid‐infrared plasmonic resonances in PEDOT antenna arrays. Their optical extinction peaks can be reversibly switched ‘OFF’ and ‘ON’ by tuning the polaronic charge carrier concentration via the polymer's redox state, offering modulation of optical responses in the thermal mid‐infrared range including around 10 µm ...
