Homework Statement
I need to calculate |ψ(x,t)|2 and find how the wave packet moves in time.
Homework Equations
I am given these three equations:
(1) ψ(x,0)=∫dp A(p) Exp[ipx/hbar] where A(p) = C Exp[-a(p-p0)/(hbar2 )]
Integrate from negative infinity to positive infinity
At a later time the wave function changes to:
(2) ψ(x,t)=∫dp A(p) Exp[ipx/hbar-ip2t/(2m*hbar)]
Integrate from negative infinity to positive infinity
The Attempt at a Solution
My first step was to normalize the wave function by finding the value of C. I did this by solving:
∫|A(p)|2 dp =1
Integrate from negative infinity to positive infinity
I found C2=√(2a/(∏*hbar2))
Once I normalized it, I solved integral (2). I then solved for |ψ(x,t)|2; The answer I got is extremely long and depends on t. I was told that having more than a certain amount of linear combinations for a solution cause the wave function to be dependent on time. Is that correct or am I missing the point entirely? Any help would be greatly appreciated!
