Published in Phys. Rev. Lett.: Edge-State Wave Functions from Momentum-Conserving Tunneling Spectroscopy
We employ the lowest 5 modes of a quantum wire to probe adjacent edge-states in momentum conserving tunneling spectroscopy. Combined with numerical Schrödinger-Poisson simulations this is a powerful technique to probe edge-state wave functions. Collaboration with UCLA and Sao Paulo on theory and with Harvard and Princeton (samples).
