Berry Phase and the Breakdown of the Quantum to Classical Mapping for the Quantum Critical Point of the Bose-Fermi Kondo model
Stefan Kirchner, Qimiao Si
The phase diagram of the Bose-Fermi Kondo model contains an SU(2)-invariant Kondo-screened phase separated by a continuous quantum phase transition from a Kondo-destroyed local mom…
The Bose-Fermi Kondo model with a singular dissipative spectrum: Exact solutions and their implications
Jianhui Dai, Qimiao Si, C. J. Bolech
Quantum dissipation induces a critical destruction of a Kondo screened state, which is of interest in the contexts of quantum critical heavy fermion metals and magnetic nanostructu…
Quantum Criticality in Ferromagnetic Single-Electron Transistors
Stefan Kirchner, Lijun Zhu, Qimiao Si +1
Considerable evidence exists for the failure of the traditional theory of quantum critical points (QCPs), pointing to the need to incorporate novel excitations. The destruction of…
Magnetic Quantum Phase Transitions in Kondo Lattices
Qimiao Si, Jian-Xin Zhu, D. R. Grempel
The identification of magnetic quantum critical points in heavy fermion metals has provided an ideal setting for experimentally studying quantum criticality. Motivated by these exp…
Reply to a Comment of M. Continentino on "Universally diverging Gruneisen parameter and the magnetocaloric effect close to quantum critical points"
Lijun Zhu, Markus Garst, Achim Rosch +1
We show that the comment [cond-mat/0408217] by Continentino on our recent paper [PRL 91, 066404 (2003), cond-mat/0212335] reaches incorrect conclusions as the comment wrongly extra…
Quantum critical properties of the Bose-Fermi Kondo Model in a large-N limit
Lijun Zhu, Stefan Kirchner, Qimiao Si +1
Studies of non-Fermi liquid properties in heavy fermions have led to the current interest in the Bose-Fermi Kondo model. Here we use a dynamical large-N approach to analyze an SU(N…
