Re: REgarding a function for integration from zero to t

[Paul Nation]

You were not doing your args correctly.  You could also do things a bit more cleanly by making the changes:

H = [H0, [H1, '0.132*exp(-((t-2.5*tau)**2)/tau**2)']]

output = mesolve(H, psi0, tlist, c_op_list,

        [gg0*gg0.dag(), uu0*uu0.dag(),  xx0*xx0.dag(), yy0*yy0.dag()

        , yy1*yy1.dag(), gg1*gg1.dag(), gg2*gg2.dag(), gg3*gg3.dag()], args={'tau':tau})

  Dear Sir,

               Thank you for developing the qutip. Actually, I am reproducing the result of my own paper published in PRB ( J. K Verma and P. K PathakPHYSICAL REVIEW B 94 , 085309 (2016)) using qutip. That time all the simulations was done with programming in C.
  Some results have been reproduced successfully but I am facing the problem in reproducing the emission probability. Therefore I need your help. After it I will also upload it in tutorial section. Looking for four help.


  Thank You,

I should probably post the result as well.
