Theory of Néel and Valence-Bond-Solid Phases on the Kagome Lattice of Zn-paratacamite
Michael J. Lawler, Lars Fritz, Yong Baek Kim +1
Recently, neutron scattering data on powder samples of Zn-paratacamite, ZnCu(OH)Cl, with small Zn concentration has been interpreted as evidence for valence b…
Quantum phase transitions in a resonant-level model with dissipation: Renormalization-group studies
Chung-Hou Chung, Matthew T. Glossop, Lars Fritz +3
We study a spinless level that hybridizes with a fermionic band and is also coupled via its charge to a dissipative bosonic bath. We consider the general case of a power-law hybrid…
Boundary quantum criticality in models of magnetic impurities coupled to bosonic baths
Serge Florens, Lars Fritz, Matthias Vojta
We investigate quantum impurity problems, where a local magnetic moment is coupled to the spin density of a bosonic environment, leading to bosonic versions of the standard Kondo a…
Theory of inelastic scattering from quantum impurities
L. Borda, L. Fritz, N. Andrei +1
We use the framework set up recently to compute non-perturbatively inelastic scattering from quantum impurities [G. Zaránd {\it et al.}, Phys. Rev. Lett. {\bf 93}, 107204 (2004)] t…
