Comment on “Ratchet universality in the presence of thermal noise”
(2013)
A recent paper [P. J. Martínez and R. Chacón, Phys. Rev. E 87, 062114 (2013)] presents numerical simulations on a system exhibiting directed ratchet transport of a driven overdamped Brownian particle subjected to a spatially ...

Should we measure plutonium concentrations in marine sediments near Fukushima?
(Springer, 2013)
Pu contamination originating from Fukushima accident has not been detected in marine sediment samples collected outside a 30 km circle around the plant. It is shown, by means of numerical modelling, that if any impact ...

Infinite charge mobility in muscovite at 300K
(IOP, 2017)
Evidence is presented for infinite charge mobility in natural crystals of muscovite mica at room temperature. Muscovite has a basic layered structure containing a flat monatomic sheet of potassium sandwiched between ...

Universal asymptotic behavior in nonlinear systems driven by a two-frequency forcing
(American Physical Society, 2013)
We examine the time-dependent behavior of a nonlinear system driven by a two-frequency forcing. By using a nonperturbative approach, we are able to derive an asymptotic expression, valid in the long-time limit, for the ...

Optical and electrical properties of the transparent conductor SrVO3 without long-range crystalline order
(AIP Publishing, 2018-01-08)
It has been shown recently that the perovskite oxide SrVO3 is a transparent conductor with optical and electrical properties outreaching those of the most used material indium tin oxide (ITO). These properties, observed ...

Growth of nanocolumnar thin films on patterned substrates at oblique angles
(Wiley-VCH Verlag, 2019)
The influence of one dimensional substrate patterns on the nanocolumnar growth of thin films deposited by magnetron sputtering at oblique angles is theoretically and experimentally studied. A well‐established growth model ...

Propagation studies for the construction of atomic macro-coherence in dense media as a tool to investigate neutrino physics
(EDP Sciences, Società Italiana di Fisica, Springer-Verlag, 2017)
In this manuscript we review the possibility of inducing large coherence in a macroscopic dense target by using adiabatic techniques. For this purpose we investigate the degradation of the laser pulse through propagation, ...

Dark lattice solitons in one-dimensional waveguide arrays with defocusing saturable nonlinearity and alternating couplings
(2012)
In the present work, we examine “binary” waveguide arrays, where the coupling between adjacent sites alternates between two distinct values C1 and C2 and a saturable nonlinearity is present on each site. Motivated by ...

Electronic structure of porphyrin-based metal– organic frameworks and their suitability for solar fuel production photocatalysis
(Royal Society of Chemistry, 2015)
Metal–organic frameworks (MOFs) can be exceptionally good catalytic materials thanks to the presence of active metal centres and a porous structure that is advantageous for molecular adsorption and confinement. We present ...

Assessing emergency situations and their aftermath in urban areas: The EMRAS II Urban Areas Working Group
(EDP Sciences, 2011)
The Urban Areas Working Group is part of the International Atomic Energy Agency’s EMRAS II (Environmental Modelling for Radiation Safety) Programme. The goal of this Working Group is to test and improve the capabilities ...
