Quantum Mechanics Flashcards
1
Q
value of phi outside well
A
0 to stop infinite energies
2
Q
What does the hamiltonian give
A
the total energy
3
Q
what is the continuity
A
phi1 = phi2 phi'1 = phi'2 unless infinite v
4
Q
odd states have…
A
even parity
5
Q
even states have….
A
odd parity
6
Q
differences in energy for finite well
A
lower due to bleeding into walls
7
Q
bound states for finite
A
even at least one bound state
odd not always a bound state
8
Q
after tunnelling the particle is
A
unbounded plane wave
9
Q
what happens when energy is measured
A
the system collapses
10
Q
fluctuation in energy
A
=0
11
Q
when do fluctuations occur
A
when there is a superposition of states
12
Q
fluctuation in momentum
A
=momentum
13
Q
what does modifying the well do
A
increases the wavelength
14
Q
what is degeneracy
A
multiple states with the same energy
