The modulated spin liquid: a new paradigm for URuSi
C. Pepin, M. R. Norman, S. Burdin +1
We argue that near a Kondo breakdown critical point, a spin liquid with spatial modulations can form. Unlike its uniform counterpart, we find that this occurs via a second order ph…
Multiple temperature scales of the periodic Anderson model: the slave bosons approach
S. Burdin, V. Zlatic
The thermodynamic and transport properties of intermetallic compounds with Ce, Eu, and Yb ions are discussed using the periodic Anderson model with an infinite correlation between…
Nonlocal interactions in doped cuprates: correlated motion of Zhang-Rice polarons
L. Hozoi, S. Nishimoto, G. Kalosakas +2
In-plane, inter-carrier correlations in hole doped cuprates are investigated by ab initio multiconfiguration calculations. The dressed carriers display features that are reminiscen…
Electronic states and magnetic excitations in LiV2O4: Exact diagonalization study
Sebastien Burdin, Natasha Perkins, Claudine Lacroix
Motivated by recent inelastic neutron scattering experiment we examine magnetic properties of LiV2O4. We consider a model which describes the half-filled localized A1g spins intera…
Kondo effect in "bad metals"
S. Burdin, V. Zlatic
We study the low-temperature properties of a Kondo lattice using the large-N formalism. For a singular density of conduction states (DOS), we generalize the single-impurity result…
