Homework Help: How to get the solution of idU(t)/dt=H(t)U(t)

  1. Sep 11, 2011 #1
    i have a problem, please help me,
    i need to implement a numerical method to solve the following Schrodinger equation:
    U(0)=1 (identity matrix)
    U(T)=UT (UT is some given unitary operator)
    where : H(t) is the Hamiltonian of the system, and
    U(t) is a unitary operator
    dimension of the operators is N*N (N is a non zero integer)

    the above problem is an ordinary diffirential equation, i know how to deal with ODE when the unknown is a real function, but when the unknown is an operator, i am confused.

    thank you
