Theory Meets Experiment in Low-Dimensional Structures with Correlated Electrons
Prague, Czech Republic, July 1 – 4, 2019
Spin correlations in graphene nanostructures probed with STM
In this talk I will discuss the emergence of non-trivial quantum spin correlations in a variety nanographene nanostructures, using a full quantum description based on exact diagonalization of the Hubbard model, in a restricted Hilbert space. In addition, I will present our theoretical understanding of how STM spectroscopy can provide information about the spin excitations in these systems.
