The technique involves shining light on a surface and measuring the energy and momentum of ejected electrons. This allows for the explicit determination of both bulk nodes and the Fermi-arc surface states.

Webpacs: Time-reversal symmetry is one of the most fundamental symmetries of nature. Classically, it is associated with the perfect reversibility of an individual particle’s path. In quantum mechanics, it is represented by invariance under an anti-unitary operator T. WebMay 26, 2024 · Over the past two decades, ARPES as a technique has matured dramatically with ever-improving resolution and continued expansion into the space, time, and spin domains. Simultaneously, the capability to synthesize new materials and apply nonthermal tuning parameters in situ has unlocked new dimensions in the study of all quantum …

WebThe TaAs family is the ideal materials class to introduce the signatures of Weyl points in a pedagogical way, from Fermi arcs to the chiral magnetotransport properties, followed by hunting for the type-II Weyl semimetals in WTe 2, MoTe 2, and related compounds. Many materials are members of big families, and topological properties can be tuned. WebJun 2, 2024 · Below, we will focus on presenting our angle-resolved photoemission spectroscopy (ARPES) data on LaAlGe and show how these data demonstrate type II Weyl fermions without relying on the agreement with theoretical calculations. Figure 2A shows the measured kz − kx Fermi surface contours of the bulk bands on the ky = 0 plane.
