Minkowski Vacuum Stress Tensor Fluctuations [PDF]

Physical Review D, 2005
We study the fluctuations of the stress tensor for a massless scalar field in two and four-dimensional Minkowski spacetime in the vacuum state. Covariant expressions for the stress tensor correlation function are obtained as sums of derivatives of a ...

Measuring the stress tensor in nitrogen-doped CVD diamond using solid-state quantum sensor [PDF]

Science and Technology of Advanced Materials
We measured the residual stress tensor in a nitrogen-doped chemical vapor deposition (001) diamond film. The stress tensor was evaluated from the amount of the shift in optically detected magnetic resonance (ODMR) spectra of NV center in the diamond.

Definition and symmetry of averaged stress tensor in granular media and its 3D DEM inspection under static and dynamic conditions

International Journal of Solids and Structures, 2019
The paper aims to clarify the stress tensor definition and its symmetry property that applies to granular media, and conducts 3D Discrete Element Method (DEM) inspection of the stress tensor definitions provided in the literature.

Stress tensor determination by modified hydraulic tests on pre-existing fractures: Method and stress constraints

Journal of Rock Mechanics and Geotechnical Engineering
The hydraulic testing of pre-existing fractures (HTPF) is one of the most promising in situ stress measurement methods, particularly for three-dimensional stress tensor determination.

Duality-invariant nonlinear electrodynamics and stress tensor flows [PDF]

Physical Review D, 2023
Given a model for self-dual non-linear electrodynamics in four spacetime dimensions, any deformation of this theory which is constructed from the duality-invariant energy-momentum tensor preserves duality invariance. In this work we present new proofs of

Loop-corrected subleading soft theorem and the celestial stress tensor [PDF]

Journal of High Energy Physics, 2022
We demonstrate that the one-loop exact subleading soft graviton theorem automatically follows from conservation of the BMS charges, provided that the hard and soft fluxes separately represent the extended BMS algebra at null infinity.

A perspective on the microscopic pressure (stress) tensor: History, current understanding, and future challenges. [PDF]

Journal of Chemical Physics, 2022
The pressure tensor (equivalent to the negative stress tensor) at both microscopic and macroscopic levels is fundamental to many aspects of engineering and science, including fluid dynamics, solid mechanics, biophysics, and thermodynamics.

The Impact of Fractal Dimension, Stress Tensors, and Earthquake Probabilities on Seismotectonic Characterisation in the Red Sea

Fractal and Fractional, 2023
The frequency–magnitude statistics of 6527 earthquakes with 1.0 ≤ ml ≤ 5.7 and focal depths between 0 and 49 km in the Red Sea region between 1980 and 2021 show that the threshold magnitude, above which most of the Red Sea earthquakes are precisely ...
