Magnetic field induced quantum criticality and the Luttinger sum rule
Y. Nishikawa, O. J. Curtin, A. C. Hewson +1
We show that when there is a sudden transition from a small to a large Fermi surface at a field-induced quantum critical point, similar to what may have been observed in some heavy…

Conditions for observing emergent SU(4) symmetry in a double quantum dot
Yunori Nishikawa, Oliver J. Curtin, Alex C. Hewson +2
We analyze conditions for the observation of a low energy SU(4) fixed point in capacitively coupled quantum dots. One problem, due to dots with different couplings to their baths,…
