Impurity Quantum Phase Transitions
Matthias Vojta
We review recent work on continuous quantum phase transitions in impurity models, both with fermionic and bosonic baths - these transitions are interesting realizations of boundary…

Quantum phase transitions in the sub-ohmic spin-boson model: Failure of the quantum-classical mapping
Matthias Vojta, Ning-Hua Tong, Ralf Bulla
The effective theories for many quantum phase transitions can be mapped onto those of classical transitions. Here we show that such a mapping fails for the sub-ohmic spin-boson mod…
