Boosting the Curie temperature with correlations in diluted magnetic semiconductors
Georges Bouzerar, Timothy Ziman, Josef Kudrnovsky
We present a quantitative theory for the effects of correlated doping on the ferromagnetism of diluted magnetic semiconductors. It predicts that room temperature ferromagnetism sho…
Theory for two-photon photoemission: transport and temperature effects
R. Knorren, G. Bouzerar, K. H. Bennemann
Using a theory which treats on equal footing transport of excited electrons and electron-phonon scattering, we are able to explain the temperature dependence of the relaxation time…
Bound-states in dimerized and frustrated Heisenberg Chains
G. Bouzerar, S. Sil
Using the Bond Operator Technique (BOT), we have studied the low energy excitationspectrum of a frustrated dimerized antiferromagnetic Heisenberg chain. In particular, we have comp…
Persistent Currents in Interacting Systems: Role of the Spin
Georges Bouzerar, Didier Poilblanc
Persistent currents flowing through disordered mesoscopic rings threaded by a magnetic flux are investigated. Models of fermions with on-site interactions (Hubbard model) or models…
