To follow up on the unexpectedly good performance of several coupled-cluster models with approximate inclusion of 3-body clusters [Rishi, V.; Valeev, E. F.
Recent research has focused on twistronics in bilayer graphene, highlighting superconducting phases at magic angles, but theoretical studies face challenges due to costly computations.
To overcome this, empirical force field approaches that account for anisotropic interlayer interactions are gaining popularity as effective alternatives.
The study introduces new atomistic empirical potentials, including an improved Lennard-Jones potential and Hod's interlayer potential, calibrated against DFT calculations, to better describe interlayer stacking, sliding, and twisting in bilayer graphynes.
