Magnetic order in lightly doped cuprates: Coherent vs. incoherent hole quasiparticles and non-magnetic impurities
Marijana Kircan, Matthias Vojta
We investigate magnetic properties of lightly doped antiferromagnetic Mott insulators in the presence of non-magnetic impurities. Within the framework of the t-J model we calculate…
Numerical Renormalization Group for Impurity Quantum Phase Transitions: Structure of Critical Fixed Points
Hyun-Jung Lee, Ralf Bulla, Matthias Vojta
The numerical renormalization group method is used to investigate zero temperature phase transitions in quantum impurity systems, in particular in the particle-hole symmetric soft-…
Kondo screening in unconventional superconductors: The role of anomalous propagators
Lars Fritz, Matthias Vojta
The Kondo effect in superconductors is frequently investigated using the local quasiparticle density of states as sole bath characteristics, i.e., the presence of anomalous propaga…
Spontaneous interlayer coherence in bilayer Kondo systems
T. Senthil, Matthias Vojta
Bilayer Kondo systems present interesting models to illustrate the competition between the Kondo effect and intermoment exchange. Such bilayers can exhibit two sharply distinct Fer…
Phenomenological lattice model for dynamic spin and charge fluctuations in the cuprates
Matthias Vojta, Subir Sachdev
Motivated by recent neutron scattering experiments on the cuprate superconductors, we present a phenomenological framework describing the dynamics of collective spin excitations co…
Phase transitions in the pseudogap Anderson and Kondo models: Critical dimensions, renormalization group, and local-moment criticality
Lars Fritz, Matthias Vojta
The pseudogap Kondo problem, describing quantum impurities coupled to fermionic quasiparticles with a pseudogap density of states, rho(omega) ~ |omega|^r, shows a rich zero-tempera…
