Growth of the Wang-Casati-Prosen counter in an integrable billiard
Zaijong Hwang, Christoph A. Marx, Joseph Seaward +2
This work is motivated by an article by Wang, Casati, and Prosen [Phys. Rev. E vol. 89, 042918 (2014)] devoted to a study of ergodicity in two-dimensional irrational right-triangul…
Ergodicity in Golden Billiards
Joseph Seaward
This comment is an analysis of the results presented by Wang et al. in their their 2014 paper on irrational right triangular billiards. They submit numerical evidence that these bi…
Comparison of time profiles for the magnetic transport of cold atoms
Thomas Badr, Dany Ben Ali, Joseph Seaward +5
We have compared different time profiles for the trajectory of the centre of a quadrupole magnetic trap designed for the transport of cold sodium atoms. Our experimental observatio…
Exactly solvable quantum few-body systems associated with the symmetries of the three-dimensional and four-dimensional icosahedra
T. Scoquart, J. J. Seaward, S. G. Jackson +1
The purpose of this article is to demonstrate that non-crystallographic reflection groups can be used to build new solvable quantum particle systems. We explicitly construct a one-…
