*Dynamically screened collective activities in layered and 
two-dimensional materials*

In many-body perturbation theory, collective excitations play a 
predominant role in understanding structural, electronic, and 
vibrational properties of matter. For instance, phonons, collective 
modes of ions, are instrumental for electrical resistivity, band gap 
renormalizations, thermal conductivity, structural phase transitions, 
charge density waves, and superconductivity. Plas-mons, collective 
electronic excitations, are crucial in comprehending optical properties, 
but can also compete and interact with phonons and, therefore, influence 
ordered phases.  In this talk I will present an overview of my work 
addressing these collective excitations in real materials, from the 
density-functional-theory point of view. A particular emphasis will be 
on the dynamical (nonadiabatic) effects of phonons and electron-phonon 
coupling, role of dynamical screening, plasmon-phonon coupling, 
dissipative effects, and ultrafast non-equilibrium dynamics. These 
dynamical aspects are investigated in a number of bulk and 
quasi-two-dimensional materials relevant in condensed matter physics and 
material science, such as graphene, transition metal dichalcogenides, 
magnesium diboride, and metal surfaces. In order to underline the 
developed methodologies and the outcome of my theoretical studies, I 
will single out the results of three projects, namely, transient 
vibrational relaxation of ordered molecules on metal surfaces, 
nonadiabatic renormalization of electron-phonon coupling in conventional 
superconductors, and ultrafast dynamics of Dirac plasmon in graphene. 
Finally, the presentation will also contain my future scientific and 
funding plans.
