Two-dimensional discrete solitons in rotating lattices
(2007)
We introduce a two-dimensional discrete nonlinear Schrödinger (DNLS) equation with self-attractive cubic nonlinearity in a rotating reference frame. The model applies to a Bose-Einstein condensate stirred by a rotating ...

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 ...

Moving discrete breathers in a β-FPU lattice revisited
(Elsevier, 2022-08)
In this work we revisit the existence, stability and dynamical properties of moving discrete breathers in -FPU lattices. On the existence side, we propose a numerical procedure, based on a continuation along a sequence of ...

Influence of spacer layer morphology on the exchange-bias properties of reactively sputtered Co ∕ Ag multilayers
(American Physical Society, 2007-09-25)
We have studied the magnetic properties of [Ag(tAg)/Co(1.2nm)]60 multilayers grown in an oxygen atmosphere. Partial oxidation of the Co layers results in the appearance of tAg dependent exchange-bias properties. A strong ...

Secuencia cronoestratigráfica del Pleistoceno Superior en Sierra Morena: la cueva de La Sima (Constantina, Sevilla)
(Sociedad Geológica de España, 2002)
La Sima of Constantina, located at the northermost part of Seville province, is a karstic cave with a thick terrigenous and chemical (f/owstone) record. These sedimentary formations are representative of the Late Quaternary ...

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 ...
