Triply degenerate nodal points and topological phase transitions in NaCu3Te2 [PDF]
, 2017 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, such as Majorana, Weyl, and Dirac fermions, while ...

Topological transition from nodal to nodeless Zeeman splitting in altermagnets [PDF]
Physical review B, 2023 In an altermagnet, the symmetry that relates configurations with flipped magnetic moments is a rotation. This makes it qualitatively different from a ferromagnet, where no such symmetry exists, or a collinear antiferromagnet, where this symmetry is a ...

Unstable Points, Ergodicity and Born’s Rule in 2d Bohmian Systems
Entropy, 2023 We study the role of unstable points in the Bohmian flow of a 2d system composed of two non-interacting harmonic oscillators. In particular, we study the unstable points in the inertial frame of reference as well as in the frame of reference of the ...

Topological semimetals with triply degenerate nodal points in θ -phase tantalum nitride [PDF]
, 2016 Using first-principles calculation and symmetry analysis, we propose that $\ensuremath{\theta}$-TaN is a topological semimetal having a new type of point nodes, i.e., triply degenerate nodal points.

Quantitative analytical theory for disordered nodal points [PDF]
, 2017 Disorder effects are especially pronounced around nodal points in linearly dispersing bandstructures as present in graphene or Weyl semimetals. Despite the enormous experimental and numerical progress, even a simple quantity like the average density of ...

(Dis)trust, (un)sefety and Cohesion: Discourses of Vaccinations in Ukraine
Український соціологічний журнал, 2021 The article is devoted to the analysis of vaccination discourses as ways of constructing and transforming social reality. Vaccination is considered, firstly, as a direction of state policy in the social and medical sphere; secondly, as a basis for ...

Coexistence of Weyl fermion and massless triply degenerate nodal points [PDF]
, 2016 By using first-principles calculations, we propose that WC-type ZrTe is a new type of topological semimetal (TSM). It has six pairs of chiral Weyl nodes in its first Brillouin zone, but it is distinguished from other existing TSMs by having additional ...

Disorder-induced exceptional points and nodal lines in Dirac superconductors [PDF]
Physical review B, 2019 We consider the effect of disorder on the spectrum of quasiparticles in the point-node and nodal-line superconductors. Due to the anisotropic dispersion of quasiparticles disorder scattering may render the Hamiltonian describing these excitations non ...

Winding numbers of nodal points in Fe-based superconductors [PDF]
, 2017 We analyze the nodal points in multi-orbital Fe-based superconductors from a topological perspective. We consider the $s^{+-}$ gap structure with accidental nodes, and the $d$-wave gap with nodes along the symmetry directions.
