Configurational entropy and instability of tachyonic braneworld

Physics Letters B, 2020
We consider tachyonic braneworld with a bulk cosmological constant and investigate a configurational entropy of various magnitudes of scale factor. It is found that for a bulk negative/zero cosmological constant, the configurational entropy has a global ...

A holographic bottom-up description of light nuclide spectroscopy and stability

Physics Letters B, 2022
This work explores a holographic proposal to describe light nuclide spectroscopy by considering extensions to the well-known bottom-up AdS/QCD proposals, the hardwall and softwall models.

Entropies in Electric Circuits

Entropy
The present study examines the relationship between thermal and configurational entropy in two resistors in parallel and in series. The objective is to introduce entropy in electric circuit analysis by considering the impact of system geometry on energy ...

Configurational entropy of polar glass formers and the effect of electric field on glass transition

, 2016
A model of low-temperature polar liquids is constructed that accounts for configurational heat capacity, entropy, and the effect of a strong electric field on the glass transition.

Bounds on topological Abelian string-vortex and string-cigar from information-entropic measure

Physics Letters B, 2016
In this work we obtain bounds on the topological Abelian string-vortex and on the string-cigar, by using a new measure of configurational complexity, known as configurational entropy.

Phase transitions in thick branes endorsed by entropic information

Physics Letters B, 2017
The so-called configurational entropy (CE) framework has proved to be an efficient instrument to study nonlinear scalar field models featuring solutions with spatially-localised energy, since its proposal by Gleiser and Stamapoulos.

Nanoscale chemical and structural investigation of solid solution polyelemental transition metal oxide nanoparticles

iScience, 2023
Summary: Although it has been shown that configurational entropy can improve the structural stability in transition metal oxides (TMOs), little is known about the oxidation state of transition metals under random mixing of alloys.

Gaussian excitations model for glass-former dynamics and thermodynamics

, 2006
We describe a model for the thermodynamics and dynamics of glass-forming liquids in terms of excitations from an ideal glass state to a Gaussian manifold of configurationally excited states.
