Quantum Flashcards
(6 cards)
1
Q
Block diagonal matrix
A
The blocks act independently the and so can be seen as 2 smaller matrices
2
Q
Hermitian/ adjoint
A
<a>=<b>^*</b></a>
3
Q
Hermitian operator
A
A= A dagger
4
Q
Raising and lowering operator
A
a dagger= sqrt(n+1)|n+1> and a= sqrt(n)|n-1>
5
Q
Energy of infinite potential well
A
n squared times pi square times hbar squared over 2ma^2
6
Q
Time dependent wave equation
A
The static wave equation time the exponential of minus i time E times t over hbar
