Lecture 4: methods and terminology, part II
... Due to the astronomical number of configurations, full CI is only possible for very small (diatomics) systems. Fortunately, full CI is rarely necessary, as CISD tends to be sufficiently accurate for most practical purposes. ...

... atoms). In each one of the questions (a-e) below you should give an expression that contains the parameters of the potential function, and σ, and possibly also the mass of the two atoms, m1 and m2 . (a) What is the distance rb at which the potential energy is smallest (the ”bond length”) and find ...

Minimal separable quantizations of Stäckel systems
... In the standard approach to the quantization of (1) one assumes that g = A 1 (as it has been done in the classical works [1] and [2] devoted to the problem of separability of classical Hamilton-Jacobi equation associated with (1)) This assumption it leads to severe limitations on the process of quan ...

The Power of Perturbation Theory
... Exact Perturbation Theory When the decomposition in thimbles is non-trivial, the intersection numbers n have to be determined This is easy for one-dimensional integrals, but very complicated in the path integral case, where in general they will be infinite Key idea: the thimble decomposition can be ...
