Chemical Reactivity as Described by Quantum Chemical Methods [PDF]

open access: yesInternational Journal of Molecular Sciences, 2002
Density Functional Theory is situated within the evolution of Quantum Chemistry as a facilitator of computations and a provider of new, chemical insights. The importance of the latter branch of DFT, conceptual DFT is highlighted following Parr's dictum "to calculate a molecule is not to understand it".

Quantum Chemical Studies of Light Harvesting [PDF]

open access: yesChemical Reviews, 2016
The design of optimal light-harvesting (supra)molecular systems and materials is one of the most challenging frontiers of science. Theoretical methods and computational models play a fundamental role in this difficult task, as they allow the establishment of structural blueprints inspired by natural photosynthetic organisms that can be applied to the ...

NV-plasmonics: modifying optical emission of an NV− center via plasmonic metal nanoparticles

open access: yesNanophotonics, 2022
The nitrogen-vacancy (NV) center in diamond is very sensitive to magnetic and electric fields, strain, and temperature. In addition, it is possible to optically interrogate individual defects, making it an ideal quantum-limited sensor with nanoscale ...

Ab initio calculation of energy levels for phosphorus donors in silicon

open access: yesScientific Reports, 2017
The s manifold energy levels for phosphorus donors in silicon are important input parameters for the design and modeling of electronic devices on the nanoscale. In this paper we calculate these energy levels from first principles using density functional

Variational Quantum Simulation of Chemical Dynamics with Quantum Computers

open access: yesJournal of Chemical Theory and Computation, 2022
Classical simulation of real-space quantum dynamics is challenging due to the exponential scaling of computational cost with system dimensions. Quantum computer offers the potential to simulate quantum dynamics with polynomial complexity; however, existing quantum algorithms based on the split-operator techniques require large-scale fault-tolerant ...
