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…
Dynamics of Excited Electrons in Copper: Role of Auger Electrons
R. Knorren, G. Bouzerar, K. H. Bennemann
Within a theoretical model based on the Boltzmann equation, we analyze in detail the structure of the unusual peak recently observed in the relaxation time in Cu. In particular, we…
Dynamics of Excited Electrons in Copper and Ferromagnetic Transition Metals: Theory and Experiment
R. Knorren, K. H. Bennemann, R. Burgermeister +1
Both theoretical and experimental results for the dynamics of photoexcited electrons at surfaces of Cu and the ferromagnetic transition metals Fe, Co, and Ni are presented. A model…
Nonequilibrium Magnetization Dynamics of Nickel
J. Hohlfeld, E. Matthias, R. Knorren +1
Ultrafast magnetization dynamics of nickel has been studied for different degrees of electronic excitation, using pump-probe second-harmonic generation with 150 fs/800 nm laser pul…
Composition and Structure of Protoneutron Stars
Madappa Prakash, Ignazio Bombaci, Manju Prakash +3
We investigate the structure of neutron stars shortly after they are born, when the entropy per baryon is of order 1 or 2 and neutrinos are trapped on dynamical timescales. In all…
Kaon Condensation in Neutron Star Matter with Hyperons
Paul J. Ellis, Roland Knorren, Madappa Prakash
Based on the Kaplan-Nelson Lagrangian, we investigate kaon condensation in dense neutron star matter allowing for the explicit presence of hyperons. Using various models we find th…
