Sharp Nash inequalities on manifolds with boundary in the presence of symmetries
Athanase Cotsiolis, Nikos Labropoulos
In this paper we establish the best constant for the Trace Nash inequality on a dimensional compact Riemannian manifold in the presence of symmetr…
Exponential elliptic boundary value problems on a solid torus in the critical of supercritical case
Athanase Cotsiolis, Nikos Labropoulos
In this paper we investigate the behavior and the existence of positive and non-radially symmetric solutions to nonlinear exponential elliptic model problems defined on a solid tor…
Weak Chaos and the "Melting Transition" in a Confined Microplasma System
Chris Antonopoulos, Vasileios Basios, Tassos Bountis
We present results demonstrating the occurrence of changes in the collective dynamics of a Hamiltonian system which describes a confined microplasma characterized by long--range Co…
Role of defects on the electronic and magnetic properties of CrAs/InAs and CrAs/CdSe half-metallic interfaces
I. Galanakis, I. Lekkas
We present an extended study of single impurity atoms at the interface between the half-metallic ferromagnetic zinc-blende CrAs compound and the zinc-blende binary InAs and CdSe se…
Energy localization on q-tori, long term stability and the interpretation of FPU recurrences
H. Christodoulidi, C. Efthymiopoulos, T. Bountis
We focus on two approaches that have been proposed in recent years for the explanation of the so-called FPU paradox, i.e. the persistence of energy localization in the `low-q' Four…
Theory of phonon-drag thermopower of extrinsic semiconducting single-wall carbon nanotubes and comparison with previous experimental data
Margarita Tsaousidou
A theoretical model for the calculation of the phonon-drag thermopower, , in degenerately doped semiconducting single-wall carbon nanotubes (SWCNTs) is proposed. Detailed ca…
