... Show that we can always define a new real function of time h(t) and a new hermitian operator H such that H(t) = h(t)H . Express h(t) and H in terms of c(t) and K and any other appropriate quantities. 2. Consider the functional equation for a complex-valued function of one real variable f (t + s) = f ...

... you can evaluate it explicitly, treating the integral as a contour integral in the complex E-plane and using the residue theorem. Make sure you are careful about closing the contour in the correct half-plane for t > t’ and t < t’ and that you pick up the correct pole. ...

... c. Calculate ∆S/h̄ for a particle which moves 1 mm in 1 ms for two cases. The particle is a nanoparticle made up of 100 carbon atoms in one case. The other case is an electron. For which of these would you consider the motion “quantum mechanical” and why? (2) Modern Quantum Mechanics, Problem 2.28. ...

... for every boson there is a corresponding fermion and vice versa. Richard Feynman gave another approach for Quantum Mechanics than Schrodinger’s Equation. Although his method was theoretically totally different than Schrodinger’s equation , It gave the same results. Here is the great idea: In classic ...

... For many particle systems, we may write the action as a sum over all of the particles. However, there are vast simplifications that occur. In a rigid body containing many times Avogadro’s number of particles, the rigidity constraint reduces the number of degrees of freedom to just six - three to spe ...

... analytical expression can be derived for the partition function at any density and chemical potential. In the canonical ensemble, the total number of particles, N, is fixed and an expression for the partition function can only be generated via a complicated recursion relation. In this work we apply ...
