Web3 de mai. de 2024 · Soon after the discovery of higher-order TIs, higher-order topological semimetals have also been proposed, which not only support symmetry-protected Weyl points/nodal lines and surface Fermi … Webtion, lead to universal higher-order topology. First we explain a discrete symmetry protecting the 5D Weyl semimetals, and describe dimensional reductions of the 5D Weyl semimetals to the popular HOTIs in the continuum limit. We calculate the topological charge carried by edge states of the 5D Weyl semimetal, for the most generic boundary ...

WebWe investigate higher-order Weyl semimetals (HOWSMs) having bulk Weyl nodes attached to both surface and hinge Fermi arcs. We identify a new type of Weyl node, which we dub a 2nd-order Weyl node, that can be identified as a transition in momentum space in which both the Chern number and a higher order topological invariant change. Web13 de abr. de 2024 · Nanyang Assistant Professor Guoqing Chang, a theoretical physicist at the School of Physical and Mathematical Sciences at Nanyang Technological University (NTU Singapore), has been exploring a new class of materials called higher-fold chiral semimetals.
