## Title

- title: Selective manipulation and tunneling spectroscopy of broken-symmetry quantum
    Hall states in a hybrid-edge quantum point contact
  title_type: original
  lang: en

## Description

- description: We present a device architecture of hybrid-edge and dual-gated quantum
    point contact. We demonstrate improved electrostatic control over the separation,
    position, and coupling of each broken-symmetry compressible strip in graphene.
    Via low-temperature magneto-transport measurement, we demonstrate selective manipulation
    over the evolution, hybridization, and transmission of arbitrarily chosen quantum
    Hall states in the channel. With gate-tunable tunneling spectroscopy, we characterize
    the energy gap of each symmetry-broken quantum Hall state with high resolution
    on the order of ~0.1 meV.
