Pairing in graphene: A quantum Monte Carlo study
Pairing in graphene A quantum Monte Carlo study
2014/5/28
To address the issue of electron correlation driven superconductivity in graphene, we perform a systematic quantum Monte Carlo study of the pairing correlation in the t -U-V Hubbard model on a honeyco...
Impact of the Electron Density on the Fixed-Node Errors in Quantum Monte Carlo
the Electron Density the Fixed-Node Errors Quantum Monte Carlo
2011/8/5
Abstract: We analyze the effect of increasing charge density on the Fixed Node Errors in Diffusion Monte Carlo by comparing FN-DMC calculations of the total ground state energy on a 4 electron system ...
