Born approximation - BYU Physics and Astronomy
... What is the main idea of the Born approximation? A. To develop a formalism where we express the wave function in terms of Green’s functions B. To use Helmholtz equation instead of Schrödinger equation C. To find an approximate expression for when far away from the scattering center for a given pot ...

Definition 1: Annihilation Operator Coherent State
... From the early days of physics, we are interested to learn the interaction of electromagnetic radiation with atoms and molecules. With the advent of laser the studies has received a tremendous boost. From the classical electrodynamics we know that the material medium gets polarized as the electric f ...

Quantum cryptography
... Summary of QKD • Quantum cryptography is really a method to reliably send a quantum key that is subsequently used with the “one time pad” Vernam cipher • Many “protocols” have been developed for QKD each of which use nonorthogonal basis sets – E.g. BB84 which uses (H,V) and (+45,-45) polarization s ...

Solving Linear Equations - A Mathematical Mischief Tutorial
... All over the world, people are using maths to solve simple problems. Things like calculating the cost of electrical work, food quantities, etc. In some cases, we use linear equations to define the functions we use for these. They’re generally defined in a fairly basic way, that is: y = mx + c Now, l ...
