Quantum phase transition in capacitively coupled double quantum dots
Martin R. Galpin, David E. Logan, H. R. Krishnamurthy
We investigate two equivalent, capacitively coupled semiconducting quantum dots, each coupled to its own lead, in a regime where there are two electrons on the double dot. With inc…

Local quantum critical point in the pseudogap Anderson model: finite-T dynamics and omega/T scaling
Matthew T Glossop, Gareth E Jones, David E Logan
The pseudogap Anderson impurity model is a paradigm for locally critical quantum phase transitions. Within the framework of the local moment approach we study its finite-T dynamics…
