Only Tails Matter: Average-Case Universality and Robustness in the Convex Regime
Leonardo Cunha, Gauthier Gidel, Fabian Pedregosa +2
The recently developed average-case analysis of optimization methods allows a more fine-grained and representative convergence analysis than usual worst-case results. In exchange,…
Electron-Affinity Time-Dependent Density Functional Theory: Formalism and Applications to Core-Excited States
Kevin Carter-Fenk, Leonardo A. Cunha, Juan E. Arias-Martinez +1
The particle-hole interaction problem is longstanding within time-dependent density functional theory (TDDFT) and leads to extreme errors in the prediction of K-edge X-ray absorpti…
Accurate core excitation and ionization energies from a state-specific coupled-cluster singles and doubles approach
Juan E. Arias-Martinez, Leonardo A. Cunha, Katherine J. Oosterbaan +2
We investigate the use of orbital-optimized references in conjunction with single-reference coupled-cluster theory with single and double substitutions (CCSD) for the study of core…
