Non-Additivity of Microwave-Shielded Interactions between Dipolar Molecules
Fabian Prieschl, Andreas Schindewolf, Robert E. Zillich
Theoretical models of the effective interactions between microwave-shielded polar molecules typically rely on the assumption of pairwise additivity. In this work, we test the valid…
