Modelling the electronic structure of many electrons (> 100) with self-consistent Hartree-Fock Simulations

ORAL

Abstract

In moving towards building a scalable quantum computer, it becomes important to consider the role of long-range interconnects between local arrays in scalable architectures. In particular, we are interested in building a multi-electron mediator as an interconnect on silicon MOS heterostructures. Due to the unique properties of silicon, the physics of such a mediator has to be understood for us to fully utilize it to its best. We demonstrate here that we are able to simulate multi-electron systems of up to hundreds of electrons using the Hartree-Fock method. We show the non-trivial formation of multi-electron wavefunctions and also the formation of systems with well-defined spin, paving the way for multi-electron mediators in silicon MOS systems.
