The mechanism of the NH4 ion oscillatory transport across the excitable cell membrane [PDF]

open access: yesZbornik Matice Srpske za Prirodne Nauke, 2005
This paper presents results on typical oscillations of the membrane potential induced by the excitation of the cell membrane by different concentrations of the NH4Cl solution.

Photo-Controlled Self-Assembly of Nanoparticles: A Promising Strategy for Development of Novel Structures

open access: yesNanomaterials, 2023
Photo-controlled self-assembly of nanoparticles (NPs) is an advanced and promising approach to address a series of material issues from the molecular level to the nano/micro scale, owing to the fact that light stimulus is typically precise and rapid, and

Excited to excited state scattering using weak measurements [PDF]

open access: yes, 2015
Weak measurements are a subset of measurement processes in quantum mechanics wherein the system which is being measured interacts very weakly with the measuring apparatus.

Correlations in excited states of local Hamiltonians [PDF]

open access: yes, 2011
Physical properties of the ground and excited states of a $k$-local Hamiltonian are largely determined by the $k$-particle reduced density matrices ($k$-RDMs), or simply the $k$-matrix for fermionic systems---they are at least enough for the calculation ...

Effects of Intra- and Interchain Interactions on Exciton Dynamics of PTB7 Revealed by Model Oligomers

open access: yesMolecules, 2020
Recent studies have shown that molecular aggregation structures in precursor solutions of organic photovoltaic (OPV) polymers have substantial influence on polymer film morphology, exciton and charge carrier transport dynamics, and hence, the resultant ...

Quantum quenches from an excited state

open access: yesNuclear Physics B, 2023
Determining the role of initial conditions in the late time evolution is a key issue for the theory of nonequilibrium dynamics of isolated quantum systems. Here we extend the theory of quantum quenches to the case in which before the quench the system is

Excitation Number: Characterizing Multiply Excited States

open access: yesJournal of Chemical Theory and Computation, 2017
How many electrons are excited in an electronic transition? In this Letter, we introduce the excitation number η to answer this question when the initial and final states are each modeled by a single-determinant wave function. We show that calculated η values lie close to positive integers, leading to unambiguous assignments of the number of excited ...

An Insight into the Excitation States of Small Molecular Semiconductor Y6

open access: yesMolecules, 2020
Y6 is a new type of non-fullerene acceptor, which has led to power conversion efficiencies of single-junction polymer solar cells over 17% when combined with a careful choice of polymeric donors. However, the excited state characteristics of Y6, which is

Effects and Influence of External Electric Fields on the Equilibrium Properties of Tautomeric Molecules

open access: yesMolecules, 2023
In this review, we have attempted to briefly summarize the influence of an external electric field on an assembly of tautomeric molecules and to what experimentally observable effects this interaction can lead to.

Excited-state Wigner crystals [PDF]

open access: yesThe Journal of Chemical Physics, 2017
Wigner crystals (WCs) are electronic phases peculiar to low-density systems, particularly in the uniform electron gas. Since its introduction in the early twentieth century, this model has remained essential to many aspects of electronic structure theory and condensed-matter physics.
