[Pw_forum] Convergence of Magnetization in Graphene Monovacancy Supercell

2014-10-21 Thread Haricharan Padmanabhan
Dear Quantum ESPRESSO users, I am attempting to estimate the value of the magnetism in Graphene with a mono-vacancy, using supercells of different sizes. Some background - - One would expect (from literature) the magnetism to converge to around 1.5 bohr magnetons (uB) as the supercell size is
