... for a two particle system is a function of the coordinates of particle 1, x 1 , the coordinates of particle 2, x 2 and the time, i.e. x 1, x 2, t . Such a wavefunction is governed by the Schrödinger equation as before and the energy is the total energy of the system. If particle 1 is in a state ...

Building Invariants from Spinors
... In quantum mechanics, a basic quantity that is invariant under any symmetry transformation is the inner product ⟨ψ1 |ψ2 ⟩ between state vectors. Translating to the spin-z basis, we can say that if ψ1 and ψ2 are the explicit two-component vectors representing any two states, that under a rotation, th ...

Lecture 3 Operator methods in quantum mechanics
... Although wave mechanics is capable of describing quantum behaviour of bound and unbound particles, some properties can not be represented this way, e.g. electron spin degree of freedom. It is therefore convenient to reformulate quantum mechanics in framework that involves only operators, e.g. Ĥ. Ad ...

... The wave-particle duality is fundamental to quantum mechanics. Light can behave like a particle (photon); matter can behave like a wave. The wavelength associated with a particle is inversely proportional to its momentum p: λ = h / p, where h is Planck’s constant. For cold atoms, the wavelength is l ...
