Extended Data Fig. 8: Enhanced relaxation rate near level degeneracy.
The spin relaxation time T1 measuring across the full target charge configurations for Device A (a) and Device D (b) in VJ and ΔVP gate space. The locations of level crossings are indicated as red dashed lines. This shows an enhanced spin relaxation rate near the point of level degeneracy in the respective systems. Interestingly, there are two visible transitions in Device D, between which the spin relaxation is faster than the background, potentially indicating the population of an alternative ground state.
