Momentum Fabric

Improved version of Wigner6j by Amita B Deb. This version returns zero if the triangle inequalities are not satisfied. Also, some undesired output is suppressed.

Wigner3j(j1,j2,j,m1,m2,m) returns the Wigner 3j-symbol, where j1, j2, j, m1, m2, and m are half-integers. Physically, the Wigner 3j-symbol is closely related to the Clebsch-Gordon coefficient , the square of which is the probability that a system of two particles with angular momentum j1 and j2...

This is a set of functions that allows to test the weak form market efficiency and thus the predictability of the time series returns through various tests: direct and indirect test.The direct tests are the two versions (individual and joint)of the variance ratio of Lo and MacKinlay (1988).The...

The classic Stern-Gerlach Experiment shows that atoms have a property called spin. Spin is a kind of intrinsic angular momentum, which has no classical counterpart. When the z-component of the spin is measured, one always gets one of two values: spin up or spin down.

The Rotation About a Fixed Axis example computes the angular momentum of a rigid rectangular box attached to a rotating axle. The fixed axis is in the z-direction. Users can tilt the box relative to the axle and can change the box dimensions. The simulation shows that the angular momentum vector...

This Java-script program simulates events in a Bubble Chamber. It will simulate one particle, the decay K- + p??a* a*?za*? ?Y?*+ ?Y?*- (?za*???a* a*p?Y?*-), and a Higgs decay in a Collider experiment (See Properties, under File). It also allows changes to the momentum and magnetic field, as well...
