## Description

- description: Bernal-stacked tetralayer graphene (4LG) exhibits intriguing low-energy
    properties, featuring two massive subbands and showcasing diverse features of
    topologically dis- tinct, anisotropic Fermi surfaces, including Lifshitz transitions
    and trigonal warping. Here, we study the influence of the band structure on electron
    dynamics within 4LG us- ing transverse magnetic focusing. Our analysis reveals
    two distinct focusing peaks cor- responding to the two subbands. Furthermore,
    we uncover a pronounced dependence of the focusing spectra on crystal orientations,
    indicative of an anisotropic Fermi surface. Utilizing the semiclassical model,
    we attribute this orientation-dependent behavior to the trigonal warping of the
    band structure. This phenomenon leads to variations in electron trajectories based
    on crystal orientation. Our findings not only enhance our understanding of the
    dynamics of electrons in 4LG, but also offer a promising method for probing anisotropic
    Fermi surfaces in other materials.
