Feb 14Exact Diagonalization Put Briefly.On key tools for simulating Hamiltonians — TL;DR Exact diagonalization is a common numerical technique employed to simulate Hamiltonians. It leverages the well-known linear algebraic process of diagonalization — whereby you factorize the Hamiltonian into its action with respect to its eigenbasis (finding all eigen[states/values] en route). Read on to find out how. The overarching objective is…Quantum4 min readQuantum4 min read
