In this talk, I will give an overview of Warwick’s regional ‘Centre for Scientific Computing’ (CSC) using four examples from recent research topics studied in my research group ‘Disordered Quantum Systems’. First, I review how to study the Anderson metal-insulator transition and explain the need for large Hamiltonians. Then I shall shift gear and show how numerical methods can give insight to the protein structure-function paradigm. Next, I shall introduce a numerical RG scheme in a disordered one-dimensional quantum magnet and make contact with modern MPS/MPO approaches as well as the AdS/CFT correspondence to compute correlation functions. Last, if time permits, I shall show how disorder can affect the transport properties of graphene.
