Notes Debye Shielding Debye shielding is a concept from plasma physics and electrochemistry that describes how electric fields are screened or shielded in a plasma or electrolyte due to the presence of mobile ...

Notes Schrodinger equation for a system of two interacting particles Two particles system is obviously 6 dimensional problem. We can 6 dimensional problem to three dimensional problem by introducing relative and centre of mass coordinates.For two particles 1 and ...

Notes Lande - g factor for two electron system for j j coupling The Lande g factor, often denoted as g, describes the splitting of energy levels in atoms due to the interaction of the magnetic moment associated with angular momentum (either orbital ...

Notes Double well model of a molecule The double well model is a simplified representation used in quantum mechanics to describe certain molecular systems, particularly those with bistable potential energy surfaces. In this model, the …

Notes Comparison of classical and quantum probability density of harmonic oscillator The comparison between classical and quantum probability density of a harmonic oscillator highlights some fundamental differences between classical mechanics and quantum mechanics. The harmonic …

Notes The Coherent states The eigen states of annihilation operator are known as coherent states.The normalized ket ∣α⟩ represents a quantum state in quantum mechanics. It's often used to describe a ...

Notes Classical limit in Quantum mechanics The classical limit in quantum mechanics refers to the behaviour of quantum systems becoming more similar to the predictions of classical physics when certain conditions are met, such as when ...

Notes Schrodinger picture The Schrödinger picture is one of the two fundamental ways to describe the behaviour of quantum systems in quantum mechanics, the other being the Heisenberg picture. These two pictures provide ...
