Strain-rate sensitivity of high-entropy alloys and its significance in deformation

Materials Research Letters, 2019
Strain-rate dependence in face centered cubic high entropy alloys still remains controversial despite extensive efforts on this topic. Strain-rate sensitivity reflects underlying thermally-activated deformation and the controversy boils down to the ...

Entanglement entropy from TFD entropy operator [PDF]

International Journal of Modern Physics A, 2021
In this work, a canonical method to compute entanglement entropy is proposed. We show that for two-dimensional conformal theories defined in a torus, a choice of moduli space allows the typical entropy operator of the TFD to provide the entanglement entropy of the degrees of freedom defined in a segment and their complement.

High-Temperature Mechanical Behavior of Cobalt-Free FeMnCrNi(Al) High-Entropy Alloys

Metals, 2023
The high-temperature properties of new alloys need to be investigated to guide the hot working process. The temperature sensitivity of various microstructures of Fe45Mn15Cr15Ni25 and Fe35Mn15Cr15Ni25Al10 cobalt-free high-entropy alloys was investigated ...

Field Theory Entropy, the $H$-theorem and the Renormalization Group [PDF]

, 1996
We consider entropy and relative entropy in Field theory and establish relevant monotonicity properties with respect to the couplings. The relative entropy in a field theory with a hierarchy of renormalization group fixed points ranks the fixed points ...

Modeling Urban Growth and Form with Spatial Entropy

, 2020
Entropy is one of physical bases for fractal dimension definition, and the generalized fractal dimension was defined by Renyi entropy. Using fractal dimension, we can describe urban growth and form and characterize spatial complexity. A number of fractal

Controlling conservation laws I: Entropy–entropy flux [PDF]

Journal of Computational Physics, 2021
We study a class of variational problems for regularized conservation laws with Lax's entropy-entropy flux pairs. We first introduce a modified optimal transport space based on conservation laws with diffusion. Using this space, we demonstrate that conservation laws with diffusion are "flux--gradient flows".
