On Breaking Time Reversal in a Simple, Smooth, Chaotic System
S. Tomsovic, D. Ullmo, T. Nagano
Within random matrix theory, the statistics of the eigensolutions depend fundamentally on the presence (or absence) of time reversal symmetry. Accepting the Bohigas-Giannoni-Schmit…

Quantum dot ground state energies and spin polarizations: soft versus hard chaos
Denis Ullmo, Tatsuro Nagano, Steven Tomsovic
We consider how the nature of the dynamics affects ground state properties of ballistic quantum dots. We find that ``mesoscopic Stoner fluctuations'', that arise from the residual…
