## Description

- description: 'Many topological phases host gapless boundary modes that can be markedly
    modified by electronic interactions. Even for the long-studied edge modes of quantum
    Hall phases1,2, forming at the boundaries of two-dimensional electron systems,
    the nature of such interaction-induced changes has been elusive. Despite advances
    made using local probes3,4,5,6,7,8,9,10,11,12,13, key experimental challenges
    persist: the lack of direct information about the internal structure of edge states
    on microscopic scales, and complications from edge disorder. Here we use scanning
    tunnelling microscopy to image pristine electrostatically defined quantum Hall
    edge states in graphene with high spatial resolution and demonstrate how correlations
    dictate the structures of edge channels on both magnetic and atomic length scales.
    For integer quantum Hall states in the zeroth Landau level, we show that interactions
    renormalize the edge velocity, dictate the spatial profile for co-propagating
    modes and induce unexpected edge valley polarization, which differs from the bulk.
    Although some of our findings can be understood by mean-field theory, others show
    breakdown of this picture, highlighting the roles of edge fluctuations and inter-channel
    couplings. We also extend our measurements to spatially resolve the edge state
    of fractional quantum Hall phases and detect spectroscopic signatures of interactions
    in this chiral Luttinger liquid. Our study establishes scanning tunnelling microscopy
    as a promising tool for exploring the edge physics of the rapidly expanding group
    of two-dimensional topological phases, including recently realized fractional
    Chern insulators.'
