Noble metal surfaces (Au, Ag and Cu etc.) have been extensively studied for the Shockley type surface states (SSs). Very recently, some of these Shockley SSs have been understood from the topological consideration, with the knowledge of global properties of electronic structure. In this letter, we show the existence of Dirac like excitations in the elemental noble metal Ru, Re and Os based on symmetry analysis and first principle calculations. The unique SSs driven Fermi arcs have been…

Nearly-grazing-incidence-high-temperature sputtering of Ruthenium(0001) surface
Abstract An atomically clean and ordered Ru(0001) surface with sharp low energy electron diffraction (LEED) spots, dispersing bands in angle-resolved photoemission spectroscopy, and the
Thermal Stability of Ru–Re NPs in H2 and O2 Atmosphere and Their Activity in VOCs Oxidation: Effect of Ru Precursor
The thermal stability of Ru–Re NPs on γ-alumina support was studied in hydrogen at 800 °C and in air at 250–400 °C. The catalysts were synthesized using Cl-free and Cl-containing Ru precursors and


Dirac Node Lines in Pure Alkali Earth Metals.
It is discovered that this pure metal system, surprisingly, harbors the Dirac node line (DNL) that in turn helps to rationalize many of the existing puzzles and suggests that the fascinating topological property of the DNL might naturally exist in other elemental metals as well.
Are the surface Fermi arcs in Dirac semimetals topologically protected?
It is found that, in marked contrast to Weyl semimetals, the gapless surface states of DSMs are not topologically protected in general, except on time-reversal-invariant planes of surface Brillouin zone.
Deformation and stability of surface states in Dirac semimetals
The unusual surface states of topological semimetals have attracted a lot of attention. Recently, we showed [PNAS 113, 8648 (2016)] that for a Dirac semimetal (DSM) arising from band-inversion, such
Three-component fermions with surface Fermi arcs in tungsten carbide
Topological Dirac and Weyl semimetals not only host quasiparticles analogous to the elementary fermionic particles in high-energy physics, but also have a non-trivial band topology manifested by
Topological semimetal and Fermi-arc surface states in the electronic structure of pyrochlore iridates
We investigate novel phases that emerge from the interplay of electron correlations and strong spin-orbit interactions. We focus on describing the topological semimetal, a three-dimensional phase of
Quaternary Heusler alloy: An ideal platform to realize triple point fermions
The existence of three fold rotational, mirror and time reversal symmetries often give rise to the triply degenerate nodal point (TP) in the band structure of a material. Based on point group
Triply degenerate nodal points and topological phase transitions in NaCu3Te2
Quasiparticle excitations of free electrons in condensed-matter physics, characterized by the dimensionality of the band crossing, can find their elementary-particle analogs in high-energy physics,
Type-II Weyl semimetals
This work proposes the existence of a previously overlooked type of Weyl fermion that emerges at the boundary between electron and hole pockets in a new phase of matter and discovers a type-II Weyl point, which is still a protected crossing, but appears at the contact of electron and Hole pockets in type- II Weyl semimetals.
Observation of three-component fermions in the topological semimetal molybdenum phosphide
An angle-resolved photoemission spectroscopy is used to demonstrate the existence of a triply degenerate point in the electronic structure of crystalline molybdenum phosphide, which opens up a way of exploring the new physics of unconventional fermions in condensed-matter systems.

It is shown via ab initio calculations that fcc calcium, strontium and ytterbium have topological nodal lines with the π Berry phase near the Fermi level, when spin–orbit interaction is neglected.
