Published in 2019 at "Chemical Physics"

DOI: 10.1016/j.chemphys.2019.04.024

Abstract: Abstract Large-scale four-component relativistic calculations have been carried out for excited states of the tris-(allyl)-iridium complex, Ir(C3H5)3, using the relativistic polarization propagator method. The main focus was on providing insight into the lowest excited states… read more here.

Published in 2020 at "Physical Review A"

DOI: 10.1103/physreva.101.012511

Abstract: We analyze the molecular electric dipole moments (PDMs) and static electric dipole polarizabilities of heteronuclear alkali dimers in their ground states by employing coupled-cluster theory, both in the non-relativistic and four-component relativistic frameworks. The roles… read more here.

Published in 2020 at "International Journal of Modern Physics A"

DOI: 10.1142/s0217751x20500761

Abstract: Recently, the deviation of the ratios $R(D)$, $R(D^{*})$ and $R(J/\psi)$ have been found between experimental data and the Standard Model predictions, which may be the hint of New Physics. In this work, we calculate these… read more here.
