Energy-Time Uncertainty
How are the state kets at different times correlated?
Consider some system in the initial state described as:
The state after some time t can be written as:
We dene the correlation amplitude
if we define the change in energy as
the
Time Evolution in Quantum
Mechanics
Physical systems are, in general, dynamical, i.e. they evolve in time.
The dynamics of classical mechanical systems are described by Newtons laws of
motion, while the dynamics of the classical electromagnetic eld is det
Exchange, antisymmetry and Pauli repulsion
Can we understand or provide a physical basis for the Pauli exclusion principle?
