Simulating decoherence of two coupled spins using the generalized cluster correlation expansion
Xiao Chen, Silas Hoffman, James N. Fry +1
We simulate the coherence of two coupled electron spins interacting with a bath of nuclei using the generalized cluster correlation expansion (gCCE) method. An exchange interaction…

Floquet Engineering Clock Transitions in Magnetic Molecules
Andrew Cupo, Shuanglong Liu, Silas Hoffman +2
We theoretically study Floquet engineering of magnetic molecules via a time-periodic magnetic field that couples to the emergent total electronic spin of the metal center. By focus…

Dominant spin-spin relaxation mechanism at clock transition of the complex at different concentrations
Xiao Chen, Haechan Park, Silas Hoffman +2
Spin decoherence poses a significant challenge in molecular magnets, with the nuclear spin bath serving as a prominent source. Intriguingly, spin qubits at the clock transition exh…
