Description
To answer the open questions in the fundaments of physics, new theories that reach beyond the standard model of particle physics are needed. Many of these predict a nonzero electron electric dipole moment (eEDM). While over the last decades, measurements in atomic and molecular beams and ion traps provided the most successful eEDM searches, only quite recently did the method of matrix isolation spectroscopy arise. It has the potential advantage of performing spectroscopy on unprecedented numbers of atoms/molecules. To perform such a measurement in the future, it is necessary first to understand how the trapping of atoms inside the cryogenic matrix looks in detail. In this contribution, I present what we learned so far through experiments and simulations of cesium trapped in inert argon and parahydrogen matrices.
