Ultrafast All-optical control of Multiple Light Degrees of Freedom through Mode-mixing in a Graphene Nanoribbon Metamaterial

Nikolaos Matthaiakakis, Sotiris Droulias, George Kakarantzas

The evolution of optical technologies necessitates advanced solutions for selective and dynamic manipulation of light's degrees of freedom, including amplitude, phase, polarization…

First-principles derived force field for h-BN monolayer nanostructures: Applications to sheets, nanotubes and nanotori

Aristotelis P. Sgouros, Markos Arapchatzis, Nektarios N. Lathiotakis +2

In this work, we present an empirical force field for hexagonal boron nitride (hBN) monolayers, derived via a bottom-up strategy from first principles calculations. We aim to deliv…

Porous carbon nitride fullerenes: a novel family of porous cage molecules

Zacharias G. Fthenakis, Nektarios N. Lathiotakis

We propose and study theoretically a novel family of cage molecules, the porous carbon nitride fullerenes (PCNFs), which can be considered the zero-dimensional counterparts of the…

Cactus-like Metamaterial Structures for Electromagnetically Induced Transparency at THz frequencies

Savvas Papamakarios, Odysseas Tsilipakos, Ioannis Katsantonis +7

THz metamaterials present unique opportunities for next generation technologies and applications, as they can fill the ``THz gap'' originating from the weak response of natural mat…

Temporal coupled-mode theory in nonlinear resonant photonics: From basic principles to contemporary systems with 2D materials, dispersion, loss, and gain

Thomas Christopoulos, Odysseas Tsilipakos, Emmanouil E. Kriezis

Temporal coupled-mode theory (CMT) is an acclaimed and widely used theoretical framework for modeling the continuous wave (CW) response and temporal dynamics of any integrated or f…

Effective local potentials for density and density-matrix functional approximations with non-negative screening density

Thomas C. Pitts, Sofia Bousiadi, Nikitas I. Gidopoulos +1

A way to improve the accuracy of the spectral properties in density functional theory (DFT) is to impose constraints on the effective, Kohn-Sham (KS), local potential [J. Chem. Phy…
