The method is based on a phase-space description of light propagating through an optical system. The propagation of light rays are governed by Hamilton's equations. Conservation of energy and etendue for a beam of light, allow us to derive a Liouville's equation for the energy propagation ...
In this work, we have created a donor-acceptor polariton microcavity suitable for studying the interplay of light-matter coupling and molecular parameters, using thin-film layers of semiconducting single-walled carbon nanotubes (CNTs) with two different optical bandgap energies. Semiconducting CNTs have ...
The ground-state properties, energy E and mean square of inter-particle separations ⟨r2⟩, were obtained by solving the Schrödinger equation −∂Ψ(RR,τ)∂τ=(H−Er)Ψ(RR,τ) , (1) written in imaginary-time τ=it/ℏ, for the Hamiltonian H. The reference energy Er is...
We revisit the theoretical priors used for inferring Dark Energy (DE) parameters. Any DE model must have some form of a tracker mechanism such that it behaved as matter or radiation in the past. Otherwise, the model is fine-tuned. We construct a model-independent parametrization that takes th...
If the current efficiency is 100% as is often the case for well-designed practical fuel cells, substituting the definitions for the various efficiencies into the above equation lead to ηFC=ΔgΔh×EEr×1=ErEtn×EEr×1=EEtn or (1.91)ηFC=EEtn Therefore, the overall free energy convers...

In this case, vv is actually equal to the speed of light, 299,792,458 meters per second, which we denote as cc. The next equation we need to consider in finding the energy to wavelength formula is the Planck-Einstein relation: E=h×fE=h×f , where: EE - Photon energy, in J; ...
Consider this simple thought: Adding light to the equation is like adding energy to the equation. This simple difference results in very different outcome of observable field symmetry. Why?NASA Goddard Oct 2018: Gravity dynamics of black holes, or rather permanent magnetic repulsion seen through ...
If we decompose the variable A into \(A=\overline{A}+A^{\prime}+A^\ast\), where overbar, prime, and star denote large-, meso- and submesoscale component, respectively, the EKE budget equation for mesoscale can be written as follows55. $$\begin{array}{rcl}\frac{\partial }{\partial...
15,58). The up-front capacity costs (Up_cost0 in year t = 0), the annual operation and maintenance cost (O&Mt), the asset replacement (Rt, battery and PV inverter at year 10) and financial costs (Ft) were taken into consideration by the following equation: $${{{\mathrm{...
