Existence and uniqueness of a finite energy solution for the mixed value problem of porous thermoelastic bodies

open access: yesBoundary Value Problems, 2021
We consider the mixed problem with boundary and initial data in thermoelasticity of porous bodies with dipolar structure. By generalizing some known results developed by Dafermos in a more simple case of the classical theory of elasticity, we prove new ...

Weak solutions in Elasticity of dipolar bodies with stretch [PDF]

open access: yesCarpathian Journal of Mathematics, 2013
In the present paper we generalize the results obtained by Iesan and Quintanilla for microstretch elastic bodies in order to cover the dipolar elastic materials with stretch. For the boundary value problem considered in this context, we use some results from the theory of semigroups of the linear operators in order to prove the existence and uniqueness

An extension of Gronwall inequality in the theory of bodies with voids

open access: yesOpen Physics, 2020
In this paper, we obtain a generalization of the Gronwall’s inequality to cover the study of porous elastic media considering their internal state variables.

Many-Body Localization in Dipolar Systems

open access: yesPhysical Review Letters, 2014
Systems of strongly interacting dipoles offer an attractive platform to study many-body localized phases, owing to their long coherence times and strong interactions. We explore conditions under which such localized phases persist in the presence of power-law interactions and supplement our analytic treatment with numerical evidence of localized states

Ab Initio Study of Fine and Hyperfine Interactions in Triplet POH

open access: yesMolecules, 2022
Phosphorous-containing molecules have a great relevance in prebiotic chemistry in view of the fact that phosphorous is a fundamental constituent of biomolecules, such as RNA, DNA, and ATP.

Vorticity Determines the Force on Bodies Immersed in Active Fluids. [PDF]

open access: yesPhysical Review Letters, 2021
When immersed into a fluid of active Brownian particles, passive bodies might start to undergo linear or angular directed motion depending on their shape.

On a generalized relaxed Saint–Venant principle

open access: yesBoundary Value Problems, 2018
The goal of this paper is to obtain an extension of the relaxed Saint–Venant principle in order to cover the thermoelasticity of dipolar porous bodies. According to this principle, for a finite time t>0 $t>0$, we identify a bounded domain Dt $\mathcal{D ...

Giant frequency-selective near-field energy transfer in active--passive structures [PDF]

open access: yes, 2016
We apply a fluctuation electrodynamics framework in combination with semianalytical (dipolar) approximations to study amplified spontaneous energy transfer (ASET) between active and passive bodies.

The Effects of Rotation Rate on Deep Convection in Giant Planets with Small Solid Cores [PDF]

open access: yes, 2006
We study how the pattern of thermal convection and differential rotation in the interior of a giant gaseous planet is affected by the presence of a small solid core as a function of the planetary rotation rate.
