Prediction for the singlet-triplet excitation energy for the spinel MgTiO using first-principles diffusion Monte Carlo
Brian Busemeyer, Gregory J. MacDougall, Lucas K. Wagner
The spinel, MgTiO, undergoes a transition into a dimerized state at low temperatures that is expected to be a spin singlet. However, no signature of a singlet-triplet trans…

Computation of the unifying thread in high temperature superconductors from first principles quantum Monte Carlo
Awadhesh Narayan, Brian Busemeyer, Lucas K. Wagner
It has long been a challenge to describe the origin of unconventional superconductivity. The two known examples with high Tc, based on iron and copper, have very different electron…
