Towards highly accurate calculations of parity violation in chiral molecules: relativistic coupled-cluster theory including QED-effects

Abstract

Parity-violating energies $E_{PV}$ of the $H_2{X}_2$ X = O, S, Se, Te, Po) molecules are reported, calculated as analytical expectation values at the relativistic coupled-cluster singles-and-doubles (CCSD) level using property-optimized basis sets. Radiative corrections to the $E_{PV}$ was investigated using effective QED-potentials and found to reach a maximal value of 2.38% for $H_{2}P{o}_2$ . However, this result depends on the choice of effective self-energy potential and may indicate limitations to their domain of validity.
