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…
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…
Quantum phase transitions out of the heavy Fermi liquid
T. Senthil, Subir Sachdev, Matthias Vojta
We review recent work on the instability of the heavy Fermi liquid state (FL) of the Kondo lattice towards a magnetic metal in which the local moments are not part of the Fermi sea…
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…
