Theory of out-of-equilibrium electron and phonon dynamics in metals after ultrafast laser excitation
Ulrike Ritzmann, Peter M. Oppeneer, Pablo Maldonado
The out-of-equilibrium dynamics of electrons and phonons upon laser excitation are often described by the two-temperature model, which assumes that both subsystems are separately i…
Magneto-structural correlations in a systematically disordered B2 lattice
