There are few phenomena in condensed matter physics that are defined only by the fundamental constants and do not depend on material parameters. Examples are the resistivity quantum, h/e2 (h is Planck's constant and e the electron charge), that appears in a variety of transport experiments and the magnetic flux quantum, h/e, playing an important role in the physics of superconductivity. By and large, sophisticated facilities and special measurement conditions are required to observe any of… Expand

Universal layer number in graphite
Graphene absorbs light in accordance with the fine-structure constant α  ≃ 1/137. The α value is universal in the sense that it is unrelated to material parameters but solely related to theExpand
Light absorption in distorted graphene
We model the low energy dynamics of graphene in the continuum in terms of a version of reduced quantum electrodynamics (QED) restricting fermions to a (2 + 1)-dimensional brane, while photons remainExpand
Fine structure constant and quantized optical transparency of plasmonic nanoarrays.
A plasmonic system in which relative optical transparency is determined solely by the fine structure constant is described and it is shown that its relative transparency can be quantized in the near-infrared, which is attributed to the quantized contact resistance between the nanoparticles and the metallic sublayer.

Refractive Properties of Graphene in a Medium-Strong External Magnetic field
1-loop quantum corrections are shown to induce large effects on the refractive index n inside a graphene strip in the presence of a constant and uniform external magnetic field B orthogonal to it.Expand
1 Electronic Transport and Optical Properties of Graphene
The enormous list of publications on transport measurements in graphene starts with the seminal papers by the groups from Manchester and Columbia [1a]. Already these studies indicated a very robustExpand
“Relativistic” Nonlinear Electromagnetic Processes in Graphene
As a condensed matter with unique nonlinear electromagnetic properties and, moreover, of “relativistic” nature of the interaction with strong electromagnetic radiation fields, in this chapter we willExpand
Graphene(s): Tuning their Nonlinear Optical Response
The present results can shed more light on the N LO response of graphene derivatives and the operational physical mechanisms while they can provide a guide for the efficient tuning of the NLO properties in view of specific applications in photonics and optoelectronics. Expand
Dirac electrons in graphene-based quantum wires and quantum dots.
The study reveals that zero-energy edge states are also present in graphene quantum dots, and due to the formation of sub-bands in the ribbons it is possible to spatially localize some of the electronic modes using a p-n-p junction. Expand
Ultrafast electron transport in graphene and magnetic nanostructures
Ultrafast terahertz spectroscopy is an ideal tool for observation of dynamics of charge, lattice and spin in solids on the most elementary timescale: in the regime ωτ ~ 1, where ω is theExpand
The evolution of electronic structure in few-layer graphene revealed by optical spectroscopy
Using the Kubo formula, it is found that the complete infrared conductivity spectra for the different FLG crystals can be reproduced reasonably well within the framework a tight-binding model. Expand


The rise of graphene.
Owing to its unusual electronic spectrum, graphene has led to the emergence of a new paradigm of 'relativistic' condensed-matter physics, where quantum relativistic phenomena can now be mimicked and tested in table-top experiments. Expand
Unusual microwave response of dirac quasiparticles in graphene.
It is shown that microwaves are an excellent probe of their unusual dynamics and the diagonal and Hall conductivities at small Omega become independent of B but remain nonzero and show a structure associated with the lowest Landau level. Expand
Universal optical conductance of graphite.
The calculations within the Slonczewski-Weiss-McClure model explain well why the interplane hopping leaves the conductance of graphene sheets in graphite almost unchanged for photon energies between 0.1 and 0.6 eV, even though it significantly affects the band structure on the same energy scale.

Electromechanical Resonators from Graphene Sheets
The thinnest resonator consists of a single suspended layer of atoms and represents the ultimate limit of two-dimensional nanoelectromechanical systems and is demonstrated down to 8 × 10–4 electrons per root hertz. Expand
Dynamical Conductivity and Zero-Mode Anomaly in Honeycomb Lattices
A topological anomaly present at zero energy is shown to give rise to a peculiar and singular behavior of the dynamic and static conductivity in two-dimensional honeycomb lattices. A calculation in aExpand

I am writing with a simple plea to balance the voluminous articles about treatment in your journal with a modicum of information about nature and caring effects to rekindle the perception of physicians as healers, not only treaters, who relish the gifts of nature, and foster the humanistic aspect of medicine that has thrived for millennia.
