Four-component relativistic calculations in a multiwavelet basis with improved convergence
Jacopo Masotti, Roberto Di Remigio Eikås, Christian Tantardini +1
We revive an approach to solve the Dirac equation originally proposed by Kutzelnigg which makes use of the squared Dirac operator . This approach holds the…
Scalar relativistic effects with Multiwavelets: Implementation and benchmark
Anders Brakestad, Stig Rune Jensen, Christian Tantardini +6
The importance of relativistic effects in quantum chemistry is widely recognized, not only for heavier elements but throughout the periodic table. At the same time, relativistic ef…
Full Breit Hamiltonian in the Multiwavelets Framework
Christian Tantardini, Roberto Di Remigio Eikås, Magnar Bjørgve +2
New techniques in core-electron spectroscopy are necessary to resolve the structures of oxides of -elements and other strongly correlated materials that are present only as powd…
