Conversion Rules for Weyl Points and Nodal Lines in Topological Media. [PDF]
Physical Review Letters, 2018 According to a widely held paradigm, a pair of Weyl points with opposite chirality mutually annihilate when brought together. In contrast, we show that such a process is strictly forbidden for Weyl points related by a mirror symmetry, provided that an ...

New nanoporous graphyne monolayer as nodal line semimetal: Double Dirac points with an ultrahigh Fermi velocity [PDF]
Carbon, 2018 Two-dimensional (2D) carbon materials play an important role in nanomaterials. We propose a new carbon monolayer, named hexagonal-4,4,4-graphyne (H4,4,4-graphyne), which is a nanoporous structure composed of rectangular carbon rings and triple bonds of ...

Left-right asymmetry: Nodal points [PDF]
Journal of Cell Science, 2003 The striking left-right asymmetry of visceral organs is known to depend on left- and right-side-specific cascades of gene expression during early embryogenesis. Now, developmental biologists are characterizing the earliest steps in asymmetry determination that dictate the sidedness of asymmetric gene expression.

Surface and 3D Quantum Hall Effects from Engineering of Exceptional Points in Nodal-Line Semimetals. [PDF]
Physical Review Letters, 2017 We show that, under a strong magnetic field, a 3D nodal-line semimetal is driven into a topological insulating phase in which the electronic transport takes place at the surface of the material. When the magnetic field is perpendicular to the nodal ring,

Limit Weierstrass points on nodal reducible curves [PDF]
Transactions of the American Mathematical Society, 2007 In the 1980s D. Eisenbud and J. Harris posed the following question: “What are the limits of Weierstrass points in families of curves degenerating to stable curves not of compact type?” In the present article, we give a partial answer to this question.

Performative Control and Rhetoric in Aotearoa New Zealand’s Response to COVID-19
Frontiers in Political Science, 2021 This article analyses how specific nodal points of performative control developed and consequently structured the discourse on Aotearoa New Zealand’s response to the COVID-19 pandemic.

Mathematical Model of Drilling Mud Movement along a Shale Shaker Screen
Advanced Engineering ResearchIntroduction. When drilling oil or gas wells, rock from the bottomhole is brought to the surface by drilling mud, which is cleaned of sludge by shale shakers at the first stage.

Intrinsic in-plane nodal chain and generalized quaternion charge protected nodal link in photonics
Light: Science & Applications, 2021 Nodal lines are degeneracies formed by crossing bands in three-dimensional momentum space. Interestingly, these degenerate lines can chain together via touching points and manifest as nodal chains.

Topological Semimetals in the SnTe Material Class: Nodal Lines and Weyl Points. [PDF]
Physical Review Letters, 2018 We theoretically show that IV-VI semiconducting compounds with low-temperature rhombohedral crystal structure represent a new potential platform for topological semimetals.
