Landauer formula for phonon heat conduction: relation between energy transmittance and transmission coefficient [PDF]
, 2012 The heat current across a quantum harmonic system connected to reservoirs at different temperatures is given by the Landauer formula, in terms of an integral over phonon frequencies ω, of the energy transmittance \hbox{$\mathcal{T}(\omega)$}𝒯(ω).

OLIFE: Tight Binding Code for Transmission Coefficient Calculation
, 2018 A new and human friendly transport calculation code has been developed. It requires a simple tight binding Hamiltonian as the only input file and uses a convenient graphical user interface to control calculations. The effect of magnetic field on junction

Approximate Transmission Coefficients in Heavy Ion Fusion [PDF]
Brazilian Journal of Physics, 2017 In this paper we revisit the one-dimensional tunnelling problem. We consider different approximations for the transmission through the Coulomb barrier in heavy ion collisions at near-barrier energies. First, we discuss approximations of the barrier shape by functional forms where the transmission coefficient is known analytically.

Transmission Eigenvalues for Operators with Constant Coefficients [PDF]
SIAM Journal on Mathematical Analysis, 2010 In this paper we study the interior transmission problem and transmission eigenvalues for multiplicative perturbations of linear partial differential operator of order $\ge 2$ with constant real coefficients. Under suitable growth conditions on the symbol of the operator and the perturbation, we show the discreteness of the set of transmission ...

Light Transmission in Fog: The Influence of Wavelength on the Extinction Coefficient
Applied Sciences, 2019 Autonomous driving is based on innovative technologies that have to ensure that vehicles are driven safely. LiDARs are one of the reference sensors for obstacle detection. However, this technology is affected by adverse weather conditions, especially fog.

Atmospheric transmission coefficient modelling in the infrared for thermovision measurements
, 2016 . The aim of this paper is to discuss different models that describe atmospheric transmission in the infrared. They were compared in order to choose the most appropriate one for certain atmospheric conditions.

FEBS Open Bio, EarlyView.Amino acids sequence of two different proteins with the same sequence (chameleon sequence—black boxes) represent in 3D structure of the proteins different secondary structures: HHHH—helical and BBB—Beta‐structural. The chains folded in water environment adopt different III‐order structures in which the chameleon fragments appear to adopt similar status

Power Summation in an Open Resonator with Aperture Coupling Elements
Advanced ElectromagneticsThe paper considers the powers summation of two sources in a hemispherical open resonator (OR). A scheme with a E- tee waveguide was used. The study was carried out in the four-millimeter wavelength range.

Tunable Transparency and Group Delay in Cavity Optomechanical Systems with Degenerate Fermi Gas
Photonics, 2023 We theoretically investigate the optical response and the propagation of an external probe field in a Fabry–Perot cavity, which consists of a mechanical mode of trapped, ultracold, fermionic atoms inside and simultaneously driven by an optical laser ...

A closed formula for the barrier transmission coefficient in quaternionic quantum mechanics [PDF]
, 2010 In this paper, we analyze, by using a matrix approach, the dynamics of a nonrelativistic particle in presence of a quaternionic potential barrier. The matrix method used to solve the quaternionic Schrodinger equation allows us to obtain a closed formula ...
