Complexity Science as Order-creation Science
... How do the race probabilities emerge from the interference of the fine-grained structure? Gell-Mann says that when we “sum over” all of the detailed factors left out—not the tips of the noses of the few horses in, say, the fourth race—the interference effects average out at approximately zero. Hence ...

We introduce in section 2 the classical dynamical systems we will focus on (mostly geodesic flows and maps on the 2dimensional torus), mentioning their degree of “chaos”. We also sketch the quantization procedures leading to quantum Hamiltonians or propagators, ...

Quantum description of the field propagating in a Kerr medium, which will be the subject of our concern in this chapter, reveals a number of interesting features that we are going to address here. Nonclassical effects associated with the anharmonic oscillator model have been discussed in many papers ...
