The Nonlinear Schrodinger Equation (NSE) is presented as:
$$i\frac{∂A}{∂z} = \frac{1}{2}β_2\frac{∂^2A}{∂t^2}-\gamma|A^2|A$$
The steady state solution
$$A(z)$$
Can be derived as an Ansatz given by:
$$ A(z) = \rho(z)e^{i\phi(z)}$$
By substituting and solving the ODE, the steady state...
Hi George,
I'm not sure I get the transition:
(a+. a)+=a+.(a+)+
Back me up here, if I have the operator (AB) and I apply the conjugate it gives me:
(AB)+=A+.B+
Right?
(I seem to be missing something really obvious here :s)
Particle Number Operator (Hermitian??)
Hey guys,
I'm studying the quantic harmonic oscillator and I'm using "Cohen-Tannoudji Quantum Mechanics Volume 1".
At some point he introduced the particle number operator, N, such that:
N=a+.a , where a+ is the conjugate operator of a.
The...
