## Description

- description: The study of the intricate interplay of electron correlation and topology
    is crucial for discovering new quantum states and phase transitions, such as the
    fractional quantum spin Hall effect and topological superconductors. In contrast
    with conventional linear electrical transport, nonlinear electrical response,
    which encompasses both symmetry and topological information remains largely unexplored
    in systems with electron correlation and topology. Here, we discover a correlated
    state in the few-layer topological semimetal TaIrTe4, using a phase diagram probed
    by the nonlinear Hall effect. Such a new state, characterized by giant nonlinearity,
    is attributed to the formation of a charge density wave (CDW) in topological semimetal,
    as evidenced by observations including Raman amplitude mode of the CDW, enhanced
    second harmonic generation and symmetry analysis in nonlinear Hall effect. The
    first-principles calculations elucidate the giant nonlinear response, resulting
    from the formation of CDW and the associated redistributed Berry curvature. Our
    findings open a new pathway to explore rich phase diagrams by electrical nonlinearity
    and pave the way for developing nonlinear electronics on correlated topological
    materials.
