... (c) Explain why the ground-state energy of a particle in the potential given in (a) is different from zero. 12. Suppose we have two particles, both of mass m, confined in 0 < x < a described by a potential V = 0 for 0 < x < a and V = for x < 0 and x > a. Assume that these two particles are not int ...

... series is divergent. Formally, we can put z=-1, whereby the infinite sum becomes the previously mentioned sum of all positive integers, and we can assign it a value given by the analytical continuation of the zetafunction to z=-1. In this way we get at the renormalized value ζ(-1) = -1/124 , i.e., n ...
