A way to represent the states and operators of a system by angle brackets and vertical bars

A state which can be represented as a wavefunction / ket in Hilbert space

A way of representing a state by several numbers, which corresponds to a complete set of commuting observables

A complete description of the observable properties of a physical system

A sufficiently isolated part in the universe for investigation

The operator that represents the total energy of the system

A state is called this if its position probability density at infinity tends to 0 for all time. we can expect to find the particles in a finite size region with certain probability

For a bound system this is an eigenstate of Hamiltonian operator

For an operator A, it is a vector that satisfies the equation A|x>=c|x> where c is a scalar

Mathematically, it is represented by a Hermitian operator

The phenomenon that a frequent measurement leads to 'freezing' of the state

Particles with integer spin

Particles with half-integer spin

Two identical fermions cannot occupy the same quantum state simultaneously

The assumption that the motion of atomic nuclei and electrons in a molecule can be separated
