    Please check my solution

    Hi guys it seems I will count on you during this semester, I have solved an exercise in quantum, but I want to someone to check my answer, can you guys help me as soon as possiple. the ex. is: propagate a gausian wave function with the K(x t x' t')= K0(x t x' t') exp {(i/2hpar)(t-t’) (...

    Sketch the functions dependance on energy

    Hi guys, I just started a course which is called quantum nanodevices and i need help in one of the exercises, ex. calculate, using periodic boundary conditions for free particles in a box, the quantity Q(ε)=(1/V) Σp δ(ε- εp) in the large system limit, 1)in three dimensions,2)in two...
