Texto completoElectronic excitations play a prominent role in a large variety of physical properties of materials, e.g., quantum transport, heat transport, conductivity, and optical properties. Depending on the electric charge of the final state, we may distinguish between charged and neutral excitations. In charged excitations, we consider electrons that are added or subtracted to the system. Direct or inverse photoemission experiments are a primary tool for the experimental observation of such processes. Instead, in neutral excitations, the total charge of the system is conserved during the excitation process. These can be probed through optical absorption measurements, both in the linear and nonlinear regimes. Density functional theory (DFT) and its time-dependent extension (TDDFT) are often the theoretical framework of first choice in the first-principles description of excitation processes. However, it is well known that DFT and TDDFT show failures and limitations due to the functional approximations which are necessary in practice. Thus, the development of more accurate approximations and theoretical extensions is an interesting and intense field of research. In this work, I develop new advances in the calculation of charged and neutral excitations. In the first part, it is shown that the fundamental gap of two-dimensional quantum dots can be accurately estimated at the effort of a standard ground-state calculation supplemented with a non-self-consistent step of negligible cost, all performed at the level of the local-density approximation. Yet, the procedure formally exploits the exchange discontinuity as expressed through the orbital-effective-potential method. In the second part, I derive an approximate potential that can capture non-vanishing exchange gaps both infinite and periodic two-dimensional systems. Although the procedure involves single-particle orbitals directly, the computational cost is comparable to standard DFT calculations. The potential approximation is applied to the artificial graphene, Kekulé distorted to open a gap at the Dirac points. In the third part of this work, nonlinear neutral excitations are investigated. In particular, I derive the optical cross section of a many-electron system subject to an impulsive electric field in the nonperturbative regime, i.e. for arbitrary values of the field strength, starting from the ground state. I show that the cross section includes absorptions from excited states for increasing intensities of the electric field - which are optical transitions that cannot be captured within the linear regime. As an example, I consider the case of a 1D two-electron model system. The analysis reveals that gerade excited states, which are dark in the linear regime, are populated in the nonlinear regime due to excited-state absorption. This analysis helps to interpret real-time TDDFT simulations which employ impulsive electric fields beyond the linear regime, as for studying processes in optical limiting phenomena. The results obtained in this Ph.D. thesis contribute to the development of accurate and feasible methods to investigate electronic excitations in quantum systems, and, more generally, to the theory development of first-principles density-functional approaches.
