Fermionic quantum criticality and the fractal nodal surface
Frank Krüger, Jan Zaanen
The complete lack of theoretical understanding of the quantum critical states found in the heavy fermion metals and the normal states of the high-T superconductors is routed in…
Pacifying the Fermi-liquid: battling the devious fermion signs
J. Zaanen, F. Krüger, J. -H. She +2
The fermion sign problem is studied in the path integral formalism. The standard picture of Fermi liquids is first critically analyzed, pointing out some of its rather peculiar pro…
Quantum Phase Transitions of Frustrated Heisenberg Antiferromagnets: a Comprehensive Renormalization Approach
Frank Krüger, Stefan Scheidl
We develop a novel renormalization approach for frustrated quantum antiferromagnets. It is designed to consistently treat spin-wave interactions all over the magnetic Brillouin zon…
CP Violation in Selected B Decays
F. Krüger, L. M. Sehgal
We summarize the results of two papers in which we have studied CP violation in inclusive and exclusive decays b -> d e^+e^-. Two CP-violating effects are calculated: the partial r…
