A Multiple Case Study of International Teaching Assistants' Investment in an ITA Training Class

Autor: Anderson, Roger W.

International teaching assistants (ITA’s) perform a variety of instructional roles in undergraduate education within North American universities. ITA training programs often exist to prepare them for such roles. Empirical work has examined ITA trai

Symmetric angular momentum coupling, the quantum volume operator and the 7-spin network: a computational perspective

Autor: Marinelli, Dimitri, Marzuoli, Annalisa, Aquilanti, Vincenzo, Anderson, Roger W., Bitencourt, Ana Carla P., Ragni, Mirco

Publikováno v: Journal Reference: Lectures Notes in Computer Science, Vol. 8579, 508-521 (2014)

A unified vision of the symmetric coupling of angular momenta and of the quantum mechanical volume operator is illustrated. The focus is on the quantum mechanical angular momentum theory of Wigner's 6j symbols and on the volume operator of the symmet

The Screen representation of spin networks. Images of 6j symbols and semiclassical features

Autor: Ragni, Mirco, Littlejohn, Robert G., Bitencourt, Ana Carla P., Aquilanti, Vincenzo, Anderson, Roger W.

Publikováno v: Lecture Notes in Computer Science, Vol. 7972, 60-72 (2013)

This article presents and discusses in detail the results of extensive exact calculations of the most basic ingredients of spin networks, the Racah coefficients (or Wigner 6j symbols), exhibiting their salient features when considered as a function o

The Screen representation of spin networks: 2D recurrence, eigenvalue equation for 6j symbols, geometric interpretation and Hamiltonian dynamics

Autor: Anderson, Roger W., Aquilanti, Vincenzo, Bitencourt, Ana Carla P., Marinelli, Dimitri, Ragni, Mirco

Publikováno v: Lecture Notes in Computer Science, Vol. 7972, 4659 (2013)

This paper treats 6j symbols or their orthonormal forms as a function of two variables spanning a square manifold which we call the "screen". We show that this approach gives important and interesting insight. This two dimensional perspective provide

3nj Morphogenesis and Semiclassical Disentangling

Autor: Anderson, Roger W., Aquilanti, Vincenzo, Marzuoli, Annalisa

Publikováno v: J. Phys. Chem. A 113 (2009) 15106-15117

Recoupling coefficients (3nj symbols) are unitary transformations between binary coupled eigenstates of N=(n+1) mutually commuting SU(2) angular momentum operators. They have been used in a variety of applications in spectroscopy, quantum chemistry a
