Symmetry-protected exceptional and nodal points in non-Hermitian systems
SciPost Physics, 2023 One of the unique features of non-Hermitian (NH) systems is the appearance of NH degeneracies known as exceptional points (EPs). The extensively studied defective EPs occur when the Hamiltonian becomes non-diagonalizable.

Automated determination of internal points of the coordinate grid of the blasted rock mass [PDF]
E3S Web of Conferences, 2020 An automated method for determining the internal points of the coordinate grid of the blasted rock mass is described. It is based on the method of determining the nodal points of the coordinate grid of the blasted rock mass, which is based on taking into

Nodal degeneracy of guided modes in uniaxial crystal slabs
Frontiers in Physics, 2023 We study the dispersions of the guided modes in the continuous uniaxial crystal slab waveguide and engineer their degeneracies through dielectric anisotropy.

Ideal topological phononic nodal chain in K2O materials class
New Journal of Physics, 2021 Nodal-chain semimetals are characterized by linked nodal rings in Brillouin zone and they have not been reported in the phonon system of atomic crystals yet. Here, based on first-principles calculations and tight-binding model analysis, we propose nearly

On the approximation of class C(0) components of physical quantities in curved coordinate systems [PDF]
Известия Саратовского университета. Новая серия: Математика. Механика. Информатика, 2022 In numerical methods for calculating the strength of technospheric objects approximating expressions of the desired values in terms of their nodal values are widely used.

Dynamics of Nodal Points and the Nodal Count on a Family of Quantum Graphs [PDF]
Annales Henri Poincaré, 2011 We investigate the properties of the zeros of the eigenfunctions on quantum graphs (metric graphs with a Schrödinger-type differential operator). Using tools such as scattering approach and eigenvalue interlacing inequalities we derive several formulas relating the number of the zeros of the n-th eigenfunction to the spectrum of the graph and of some ...

From nodal points to non-equidistribution at the Planck scale
Comptes Rendus. Mathématique, 2022 In this note, we make an observation that Laplacian eigenfunctions fail equidistribution at the Planck scale. Furthermore, equidistribution at the same scale also fails around the points where the eigenfunctions have large values.
