We have developed a numerical model system for a single active electron in an environment of three nuclei with tunable charges arranged as an equilateral triangle. This enables mimicking of both symmetric and asymmetric nuclear charge configurations, while keeping the ionization potential fixed. We investigate the interaction of these model systems with intense, few-cycle, circularly polarized infrared laser pulses and examine the asymmetries between the photoelectron spectra induced by the left- and right-circularly polarized fields. We show that these asymmetries are influenced by the initial symmetry of nuclear charge configurations. We demonstrate that few-cycle laser pulses can induce an additional asymmetry in the photoelectron spectra, which can weaken or enhance the asymmetry imprinted by the initial symmetry properties of the model system.
