DOI: 10.1002/advs.202205940
Abstract: Topological materials have been recently regarded as ideal catalysts for heterogeneous reactions due to their surface metallic states and high carrier mobility. However, the underlying relationship between their catalytic performance and topological states is under… read more here.

DOI: 10.1103/physrevb.103.024529
Abstract: We introduce a very simple and exactly solvable model that supports Fermi arcs in its ground state and excitation spectrum. These arcs come in pairs, and merge into what we call a pseudo-Fermi surface along… read more here.

DOI: 10.1103/physrevb.103.165131
Abstract: Since the discovery of the pseudogap and Fermi arc states in underdoped cuprates, the understanding of such non-Fermi-liquid states and the associated violation of Luttinger's theorem have been the central theme in correlated electron systems.… read more here.

DOI: 10.1103/physrevlett.119.076801
Abstract: The hallmark of Weyl semimetals is the existence of open constant-energy contours on their surface-the so-called Fermi arcs-connecting Weyl points. Here, we show that, for time-reversal symmetric realizations of Weyl semimetals, these Fermi arcs, in… read more here.
