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…
Critical theories for the pseudogap Kondo problem
Lars Fritz, Marijana Kircan, Matthias Vojta
We discuss quantum phase transitions in the pseudogap Kondo problem, which describes a magnetic moment coupled to conduction electrons with a power-law density of states, rho(omega…
Magnetic excitations in a bond-centered stripe phase: Spin waves far from the semi-classical limit
Matthias Vojta, Tobias Ulbricht
Using a spin-only model, we compute spin excitation spectra in a bond-centered stripe state with long-range magnetic order. We employ a bond operator formalism, which naturally cap…
