# What is functional in computational physics?

A functional is a function of a function. In DFT the functional is the electron density which is a function of space and time. The electron density is used in DFT as the fundamental property unlike Hartree-Fock theory which deals directly with the many-body wavefunction.

## What do you study in Computational physics?

Computational physics is the study of scientific problems using computational methods; it combines computer science, physics and applied mathematics to develop scientific solutions to complex problems. Computational physics complements the areas of theory and experimentation in traditional scientific investigation.

## Which is an example of Computational physics?

Example applications include the heat capacity of solids, thermal radiation, electrostatics calculations, and image processing.

## What is Computational physics algorithm?

Algorithms are the set of logical steps for a specific computational problem. These involve two steps in the first step we need to transform a problem or equations into a set of logical steps that a computer can follow and in the second step we inform the computer to perform these logical steps.

## What is computational work?

Computational modeling is the use of computers to simulate and study complex systems using mathematics, physics and computer science. A computational model contains numerous variables that characterize the system being studied.

## What is medical physics?

Medical Physics is the application of physics to healthcare; using physics for patient imaging, measurement and treatment.

## Is math a physic?

While physicists rely heavily on math for calculations in their work, they don’t work towards a fundamental understanding of abstract mathematical ideas in the way that mathematicians do. Physicists “want answers, and the way they get answers is by doing computations,” says mathematician Tony Pantev.

## Why do we use DFT in physics?

Classical DFT allows the calculation of the equilibrium particle density and prediction of thermodynamic properties and behavior of a many-body system on the basis of model interactions between particles. The spatially dependent density determines the local structure and composition of the material.

## What is the difference between MD and DFT?

DFT calculations use different reference state for the energies ( separate nucleus,electrons ) while potential energy with classical MD simulation only includes the intra and intermolecular potential energies and not the piece due to internal part of the molecular partition function.
