Fragile Topology is Unstable Under Translation Refinement
Yoonseok Hwang, Saavanth Velury, Taylor L. Hughes
Fragile topological phases become trivial upon the addition of suitable trivial bands, distinguishing them from stable topological phases. Nevertheless, various response phenomena…
Global and Local Topological Crystalline Markers for Rotation-Symmetric Insulators
Saavanth Velury, Yoonseok Hwang, Taylor L. Hughes
Crystalline symmetry can be used to predict bulk and surface properties of topological phases. For non-interacting cases, symmetry-eigenvalue analysis of Bloch states at high symme…
Embedded Topological Semimetals
Saavanth Velury, Taylor L. Hughes
Topological semimetals, such as Dirac, Weyl, or line-node semimetals, are gapless states of matter characterized by their nodal band structures and surface states. In this work, we…
Direct Transition Resonance in Atomically Uniform Topological Sb(111) Thin Films
Guang Bian, Caizhi Xu, Tay-Rong Chang +8
Atomically uniform Sb(111) films are fabricated by the method of molecular beam epitaxy on an optimized Si(111) surface. Two dimensional quantum well states and topological surface…
Drumhead Surface States and Topological Nodal-Line Fermions in TlTaSe2
Guang Bian, Tay-Rong Chang, Hao Zheng +13
A topological nodal-line semimetal is a new condensed matter state with one-dimensional bulk nodal lines and two-dimensional drumhead surface bands. Based on first-principles calcu…
