Normal ordering normal modes [PDF]
European Physical Journal C: Particles and Fields, 2021 In a soliton sector of a quantum field theory, it is often convenient to expand the quantum fields in terms of normal modes. Normal mode creation and annihilation operators can be normal ordered, and their normal ordered products have vanishing ...

Two Chebyshev Spectral Methods for Solving Normal Modes in Atmospheric Acoustics [PDF]
Entropy, 2021 The normal mode model is important in computational atmospheric acoustics. It is often used to compute the atmospheric acoustic field under a time-independent single-frequency sound source.

Detection of Mars Normal Modes From S1222a Event and Seismic Hum
Geophysical Research Letters, 2023 We present the first detection of normal modes on Mars using the vertical records from InSight's broad‐band seismometer following the marsquake that occurred on sol 1222. The proposed catalog lists 60 potential eigenfrequencies between 3 and 12 mHz.

Normal modes of a waveguide as eigenvectors of a self-adjoint operator pencil
Discrete and Continuous Models and Applied Computational Science, 2021 A waveguide with a constant, simply connected section S is considered under the condition that the substance filling the waveguide is characterized by permittivity and permeability that vary smoothly over the section S, but are constant along the ...

Perfect Invisibility Modes in Dielectric Nanofibers
Photonics, 2023 With the help of the original mathematical method for solving Maxwell’s equations, it is shown that in dielectric waveguides along with usual waveguides and quasi-normal modes, there are perfect invisibility modes or perfect non-scattering modes.

Study of IR spectra of thiacalix[4]arene with carboxyl and adamantyl groups [PDF]
E3S Web of Conferences, 2021 The IR spectra of p-(3-carboxy-1-adamantyl)thiacalix[4]arene (1) were studied. IR spectra of compound 1 do not contain bands of free hydroxyl groups. The νOH value at 3377 cm-1 signifies the formation of an intramolecular H-bond along the lower edge of ...
