Description
Understanding correlated electrons remains a challenge slowing advances in Quantum Technologies. We address this challenge with synthetic topological quantum matter built with semiconductor and graphene quantum dots. We start with quantum dots in a topological insulator and describe a strain sensor based on strain induced topological to trivial transition.
We next describe quantum dots and their arrays in semiconductor nanowires and show that they potentially host Haldane and Majorana quasiparticles, macroscopic quantum states and topologically protected qubits. We describe sublattice and twist engineering of flat electronic bands, resulting in correlations and magnetism and spontaneously broken valley and spin symmetry states in bilayer quantum dots.
