Development and Application of London Dispersion Corrections for Electronic Structure Methods
Caldeweyher, Eike-Hanno Jeremias (2020-05-19)Mean-field electronic structure methods like<em> Hartree–Fock</em> ( HF ) or <em>Kohn–Sham</em> ( KS ) <em>Density Functional Theory </em>( DFT ) do not account for long-range correlation effects and consequently ... -
Development and Application of Quantum Mechanical Tight-Binding Methods for the Exploration of Chemical Space
Pracht, Philipp (2021-11-17)This thesis centrally focuses on the systematic exploration of the so-called "chemical space" using fast quantum chemical methods. In computational chemistry any calculation requires a detailed knowledge about a molecules ... -
Development and Characterisation of Passive CMOS Sensors for Pixel Detectors in High Radiation Environments
Dieter, Yannick Manuel (2022-10-07)With the upgrade of the Large Hadron Collider (LHC) to the High-Luminosity LHC (HL-LHC), the instantaneous luminosity increases by a factor of five with respect to its design value from 2027. To keep the detectors at the ... -
