Angular momenta dynamics in magnetic and electric
... Usually when describing angular momentum in atomic or molecular physics, we use a quantummechanical approach. However, there are problems, mostly connected with the description of states with large angular-momentum quantum numbers (M 43 = = = 433,, say, in molecular physics, where the classical ap ...

... AQF has since been shown to take exponential time on some problems. For example, van Dam and Vazirani [34] construct a family of 3SAT instances for which the gap g is exponentially small. They also describe a problem that is linear on a conventional model of computation but exponential for AQF . Alt ...

The fact that there is not an exact coincidence can easily be understood: the term proportional to ln N describes fluctuations. If the partition is removed, fluctuations with larger magnitude than in the presen ...
