Multi-Parameter Step-by-Step Inversion of Resistivity Anisotropy and Application

open access: yesCejing jishu, 2023
Electromagnetic resistivity logging while drilling is widely used, which has become a required item in the inclined and horizontal offshore wells. However, due to the comprehensive influence of reservoir anisotropy, drilling fluid invasion and other ...

Linear-$T$ resistivity from low to high temperature: axion-dilaton theories

open access: yes, 2020
The linear-$T$ resistivity is one of the hallmarks of various strange metals regardless of their microscopic details. Towards understanding this universal property, the holographic method or gauge/gravity duality has made much progress.

Relativistic resistive magnetohydrodynamic reconnection and plasmoid formation in merging flux tubes [PDF]

open access: yes, 2019
We apply the general relativistic resistive magnetohydrodynamics code {\tt BHAC} to perform a 2D study of the formation and evolution of a reconnection layer in between two merging magnetic flux tubes in Minkowski spacetime.

BLOCH WAVE – ZRP SCATTERING AS A KEY ELEMENT OF SOLID STATE PHYSICS COMPUTATION: 1D EXAMPLE

open access: yesTASK Quarterly, 2016
This paper presents calculation of the electron-impurity scattering coefficient of Bloch waves for one dimensional Dirac comb potential. The impurity is also modeled as delta function pseudopotential that allows explicit solution of the Schrodinger ...

Origin of the Resistivity Anisotropy in the Nematic Phase of FeSe. [PDF]

open access: yesPhysical Review Letters, 2015
The in-plane resistivity anisotropy is studied in strain-detwinned single crystals of FeSe. In contrast to other iron-based superconductors, FeSe does not develop long-range magnetic order below the tetragonal-to-orthorhombic transition at T_{s}≈90  K ...

Modelling of changes in the resistivity of semi-insulating materials [PDF]

open access: yesMetrology and Measurement Systems, 2021
Electrical properties of semiconductor materials depend on their defect structure. Point defects, impurities or admixture contained in a semiconductor material, strongly affect its properties and determine the performance parameters of devices made on ...

Electrical Resistivity of Concrete for Durability Evaluation: A Review

open access: yes, 2017
Degradation processes in reinforced concrete structures that affect durability are partially controlled by transport of aggressive ions through the concrete microstructure. Ions are charged and the ability of concrete to hold out against transfer of ions

Introduction to tensorial resistivity probability tomography

open access: yes, 2005
The probability tomography approach developed for the scalar resistivity method is here extended to the 2D tensorial apparent resistivity acquisition mode.

Normal state resistivity of Ba$_{1-x}$K$_x$Fe$_2$As$_2$: evidence for multiband strong-coupling behavior [PDF]

open access: yes, 2011
We present theoretical analysis of the normal state resistivity in multiband superconductors in the framework of Eliashberg theory. The results are compared with measurements of the temperature dependence of normal state resistivity of high-purity Ba$_{0.

Interplay between phonon and impurity scattering in 2D hole transport

open access: yes, 2012
We investigate temperature dependent transport properties of two-dimensional p-GaAs systems taking into account both hole-phonon and hole-impurity scattering effects. By analyzing the hole mobility data of p-GaAs in the temperature range 10 K$
