Exploring Overlapping Mechanisms of Dynamic Nuclear Polarization in Type 1b HPHT Diamond
Brendan C. Sheehan, Margaret Hubble, Daphna Shimon +1
The inhomogeneous distribution of P1 centers in type 1b HPHT diamond samples allows multiple DNP mechanisms to occur within the same crystal, resulting in complex DNP spectra. At s…

Enhancing Coherence with a Clock Transition and Dynamical Decoupling in the CrMn Molecular Nanomagnet
Guanchu Chen, Brendan C. Sheehan, Ilija Nikolov +8
Molecular magnets are attractive as spin qubits due to their chemical tunability, addressability through electron-spin resonance techniques, and long coherence times. Clock transit…

Clock Transitions Generated by Defects in Silica Glass
Brendan C. Sheehan, Guanchu Chen, Jonathan R. Friedman
Clock transitions (CTs) in spin systems, which occur at avoided level crossings, enhance quantum coherence lifetimes T because the transition becomes immune to the decohering e…
