SUMMARY:TYC Lunctime Seminar: FCIQMC Simulations of Solids
DESCRIPTION:Click here to join the Seminar \n\n\n\nChristopher BradleyDepartment of Physics\, ICL \n\n\n\nAbstract:Quantum Monte Carlo (QMC) refers to a set of stochastic methods used in solving quantum many-body problems. They have a rich history in solid-state physics\, for instance in the production of very accurate benchmarks for better scaling methods like DFT. One such method is Full Configuration Interaction QMC (FCIQMC)\, which solves for the ground state of a system by evolving a population of walkers in a Hilbert space of Slater determinants. Unlike more popular Monte Carlo methods (e.g. Variational QMC\, Diffusion QMC)\, it is not dependent upon the quality of an initial trial function nor does it rely on uncontrolled approximations. This has led to its success in energy calculations of molecular systems as well as in the uniform electron gas. \n\n\n\nIn this talk\, I will give a brief summary of FCIQMC before going on to discuss its application to solids and its performance relative to other methods.

SUMMARY:TYC Lunctime Seminar: Electronic structure of twisted bilayer materials
DESCRIPTION:Click here to join the Seminar \n\n\n\nKemal AtalarDepartment of Materials\, ICL \n\n\n\nAbstract: The discovery of correlated and superconducting states in magic-angle twisted bilayer graphene has generated interest in twisted heterostructures composed of other 2D materials. For example\, signatures of superconductivity and exotic optical behaviour have been observed recently in twisted bilayers of transition metal dichalcogenides (TMDs). The theoretical and computational study of these materials using first-principles methods\, however\, remains challenging due to their large Moiré superlattice sizes at small twist angles. In this work\, accurate and efficient tight-binding models for predicting and understanding the electronic structure of twisted TMD heterostructures are developed. The first-principles TMD tight-binding model of Fang et al. is extended to twisted and hetero-bilayer structure and additional interlayer interactions between pz and dz2 orbitals are included. Finally\, the band structures and effect of twisting in various Moiré heterostructures of TMDs are demonstrated.
