    Solution of time-dependent Schroedinger Equation

    Thank you! It's very clearly presented and helpful indeed. Luckily, I know eigenstates of my Hamiltonian, there are two eigen states only (on picture attached).

    Solution of time-dependent Schroedinger Equation

    Even if ket |psi> is a linear combination of eigenkets of H?

    Solution of time-dependent Schroedinger Equation

    |psi> is a linear combination of eigenstates of H indeed. :)

    Solution of time-dependent Schroedinger Equation

    ..but how it can be solved then?!

    Solution of time-dependent Schroedinger Equation

    Hello, I am interested - is the solution of the time-dependent Schroedinger Equation on the picture attached correct? Are there any flaws in this solution? Thank you. :)

    Graduate Starting Place For Quantum Physics

    The trick with Feynman Lectures is that almost everyone who has read this gets an impression that he understands physics, but in fact most of readers still do not. The impression of easiness of the subject which the reading of the Lectures gives is often wrong, IMO.

    I guess that he equally needs exercises and solutions to these.

    Graduate Starting Place For Quantum Physics

    I prefer Zettili, Quantum Mechanics: Concepts and Applications because it's bulky in size and has plenty of examples which are very well selected and presented in detail (step-by-step approach really).

    Graduate Why Choose Liouville Representation Over Hamiltonian in Classical Mechanics?

    Hi All, I am interested what are the advantages, in general, of using Liouville representation instead of Hamiltonian representation and for what kind of problems such advantages are valid?
