Poisson's And Laplace's Equation

Poisson's And Laplace's Equation

The electric potential of the system can be calculated by relating it to the electric charge densities that give rise to the electric potential. The differential form of Gauss's law expresses the electric field's divergence in terms of the electric charge density.

The de Broglie Wavelength

The de Broglie Wavelength

In the macroscopic world, objects that are large enough to be seen by the naked eye follow the rules of classical physics. A billiard ball moving on a table will behave like a particle; it will continue traveling in a straight line unless it collides with another ball, or it is acted on by some other force, such as friction. The ball has a well-defined position and velocity or well-defined momentum, p = mv, which is defined by mass m and velocity v at any given moment. This is the typical...

Background:

Plasmon properties are crucial in nanoscience, but traditional methods like time-dependent density functional theory (TDDFT) struggle with complex systems.
Investigating the impact of size, geometry, and dimensionality on plasmon behavior requires computationally efficient methods.

Purpose of the Study:

To develop a novel multiscale formalism for studying plasmon properties in complex nanosystems.
To enhance the computational efficiency and numerical stability of plasmon simulations.

Main Methods:

A multiscale formalism based on Trotter factorization and a coarse-grained (CG) structure function derived from the electron wavefunction.
Development of a multiscale propagator that simultaneously evolves the CG structure function and electron wavefunction.
Application of the algorithm to interacting sodium nanoparticles.

Main Results:

The CG structure function evolves on a significantly longer timescale than the electron wavefunction.
The multiscale propagator demonstrates substantial efficiency gains over classical TDDFT propagators.
Improved numerical stability and the ability to use larger time steps contribute to the method's efficiency.

Conclusions:

The proposed multiscale formalism offers a computationally efficient and accurate approach for studying plasmon properties in nanosystems.
This method overcomes the limitations of TDDFT for complex nanostructures.
The demonstrated efficiency makes it suitable for investigating plasmons in systems with varying size, geometry, and dimensionality.
