Analytical formulae are given for the electrostatic potential and the electron density profiles. The results capture the features of the quantum effects which are quite different from classical physics predictions. The analytical results compare well with exact numerical solutions over a broad range of ...
In order for a monomer molecule to join the polymer chain, an electron from the double C=O bond should abandon it and “penetrate” into the space between the atoms of carbon and oxygen of the adjacent molecule with the formation of a single bond C–O (this is shown in the middle of...
We show that the initial correlations can affect quantum transport not only in the transient regime, but also in the steady-state limit when system-lead couplings are strong enough so that electron localized bound states occur in the device system....

Such a symmetric tunneling solution has advantages in a numerical treatment (as it allows to use periodic boundary conditions) and captures the same physics. The quantum-mechanical density ρq = ∣ψ∣2 for the solution (42) is given by $${\rho }_{{{\rm{q}}}(x)=\,\left\{\beg...
When is k = l in quantum tunneling? How to calculate the dielectric constant from capacitance? How many electron volts are in a cathode ray tube? How to derive the Schrodinger wave equation? What is c in the Planck constant equation?
Finally, we present a demonstration of quantum resonant tunneling. In this script, two wavepackets are incident on a double potential well, representing two independent electrons. Despite having less energy than the lower, the upper electron has a higher chance of passing through the barriers. This...
GPU TDSE solver application for the RCT calculations The GPU TDSE Solver was further applied to the calculation of the resonant charge transfer (RCT) in nanosystems, including such physical problems as electron capture during H+–H0 collision and electron tunneling between H− ion and thin metalli...
