In 2022, we have improved our theoretical methods of ab initio calculation of Tc. We combined our methods with structure prediction methods, and proposed a systematical routine to find optimal elements for lanthanum hydrides. We have successfully predicted that by doping calcium we can increase the transition temperature for lanthanum hydride to reach room-temperature with lower pressure.
In 2023, we have studied the effect of self-consistency in the calculation of electronic self-energy. We have found that the inclusion of self-consistency in self-energy is crucial in our Migdal-Eliashberg calculations. Moreover, using our methods, we have successfully reproduced the experimental Tc value of MgB2.
