Hello All
for my simulation I needed to use a different value of reduced planck constant than the SI units one. So I wanted to know what value of reduced planck constant the solvers use. Is it 1, or is it the SI one.
Any information pertaining to this would be helpful. I could not find any information on this in the documentation.
Thanking you

Hello
It seems the value of reduced planck constant used is 1 in qutip. To use the effective value of hbar=a, I divided the Hamiltonian by a, and used the schrodinger solver in qutip package on that.
I hope that is correct. I actually needed to calculate wigner distribution with this effective hbar value for a coherent state with a given ,<x> and <p>. So I used this effective value of hbar with m and omega both 1, to get the real part and imaginary value of alpha for the coherent state. 
Then for wigner distribution calculation, I used g value derived from this effective hbar.
I hope this approach is correct.
