Majorana Zero Modes Emulated in a Magnetic Molecule Chain

We theoretically predict the presence of Majorana zero modes (MZMs) in a Co trimer molecular magnet. Using parameters extracted from ab initio calculations, we find a low-energy subspace of this trimer which realizes an effective anisotropic spin-1/2 chain. We show the presence of MZMs in this system and find their response to electronic paramagnetic resonance. This response gives a fingerprint for the MZMs in this system and, moreover, can be used to extract the occupation of the MZMs in the fermionic representation.
