Efficient Excitations and Spectra within a Perturbative Renormalization Approach [PDF]

Journal of Chemical Theory and Computation, 2020
We present a self-consistent approach for computing the correlated quasiparticle spectrum of charged excitations in iterative $\mathcal{O}[N^5]$ computational time. This is based on the auxiliary second-order Green's function approach [O. Backhouse \textit{et al.}, JCTC (2020)], in which a self-consistent effective Hamiltonian is constructed by ...

Discussions for the charging efficiency of the resistor–capacitor and resistor–inductor–capacitor series circuits under different excitation sources

Energy Reports, 2022
Aiming at the resistor–capacitor (RC) series circuit and resistor–inductor–capacitor (RLC) series circuit of capacitor charging, this paper discusses the energy efficiency of the capacitor charging circuit under the four excitation conditions of the step

EFFICIENT EXCITATION OF WAVEGUIDES IN CRANK-NICOLSON FDTD [PDF]

Progress In Electromagnetics Research Letters, 2010
In this paper, we present a procedure to calculate the discrete modes propagated with Crank-Nicolson FDTD in metallic waveguides. This procedure enables the correct excitation of this kind of waveguides at any resolution. The problem is reduced to solving an eigenvalue equation, which is performed, both in a closed form, for the usual rectangular ...

Roles of the Excitation in Harvesting Energy from Vibrations. [PDF]

PLoS ONE, 2015
The study investigated the role of excitation in energy harvesting applications. While the energy ultimately comes from the excitation, it was shown that the excitation may not always behave as a source.

Limitation of room temperature phosphorescence efficiency in metal organic frameworks due to triplet-triplet annihilation

Frontiers in Chemistry, 2022
The effect of triplet-triplet annihilation (TTA) on the room-temperature phosphorescence (RTP) in metal-organic frameworks (MOFs) is studied in benchmark RTP MOFs based on Zn metal centers and isophthalic or terephthalic acid linkers (ZnIPA and ZnTPA ...

CellExcite: an efficient simulation environment for excitable cells [PDF]

BMC Bioinformatics, 2008
Brain, heart and skeletal muscle share similar properties of excitable tissue, featuring both discrete behavior (all-or-nothing response to electrical activation) and continuous behavior (recovery to rest follows a temporal path, determined by multiple competing ion flows).

An Efficient Variational Principle for the Direct Optimization of Excited States [PDF]

Journal of Chemical Theory and Computation, 2016
We present a variational function that targets excited states directly based on their position in the energy spectrum, along with a Monte Carlo method for its evaluation and minimization whose cost scales polynomially for a wide class of approximate wave functions. Being compatible with both real and Fock space and open and periodic boundary conditions,

Efficiency of Plasmon-Induced Dual-Mode Fluorescence Enhancement upon Two-Photon Excitation

Nanomaterials, 2021
Anisotropic noble metal nanoparticles supporting more than one localized surface plasmon resonance can be tailored for efficient dual-mode fluorescence enhancement by ensuring an adequate coupling to both absorption and emission bands of fluorophores ...
