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…

Resonance-Assisted Tunneling
Olivier Brodier, Peter Schlagheck, Denis Ullmo
We present evidence that tunneling processes in near-integrable systems are enhanced due to the manifestation of nonlinear resonances and their respective island chains in phase sp…
