Anomalous ballistic scaling in the tensionless or inviscid Kardar-Parisi-Zhang equation
Rodríguez Fernández, Enrique; Santalla Arribas, Silvia Noemí; Castro Ponce, Mario; Cuerno Rejado, Rodolfo (2022-08-01)The one-dimensional Kardar-Parisi-Zhang (KPZ) equation is becoming an overarching paradigm for the scaling of nonequilibrium, spatially extended, classical and quantum systems with strong correlations. Recent analytical ... -

Redondo Cubero, Andrés; Lorenz, Katharina; Palomares Simón, Francisco Javier; Muñoz Castellanos, Ángel; Castro Ponce, Mario; Muñoz García, J.; Cuerno Rejado, Rodolfo; Vázquez Burgos, Luís Fernando (2018-07-11)We have bombarded crystalline silicon targets with a 40 keV Fe%2B ion beam at different incidence angles. The resulting surfaces have been characterized by Atomic Force, Current-sensing and Magnetic Force Microscopies, ... -
Coupling of morphology to surface transport in ion-beam irradiated surfaces: Oblique incidence
Muñoz García, J.; Cuerno Rejado, Rodolfo; Castro Ponce, Mario (2008-11-15)We propose and study a continuum model for the dynamics of amorphizable surfaces undergoing ion-beam sputtering IBS at intermediate energies and oblique incidence. After considering the current limitations of more standard ... -
Coupling of morphology to surface transport in ion-beam-irradiated surfaces: normal incidence and rotating targets
Muñoz García, J.; Cuerno Rejado, Rodolfo; Castro Ponce, Mario (2009-06-03)Continuum models have proved their applicability to describe nanopatterns produced by ion-beam sputtering of amorphous or amorphizable targets at low and medium energies. Here we pursue the recently introduced ‘hydrodynamic ... -
Dimensional fragility of the Kardar-Parisi-Zhang universality class
Nicoli, Matteo; Cuerno Rejado, Rodolfo; Castro Ponce, Mario (2013-11-01)We assess the dependence on substrate dimensionality of the asymptotic scaling behavior of a whole family of equations that feature the basic symmetries of the Kardar-Parisi-Zhang (KPZ) equation. Even for cases in which, ... -
Dynamical renormalization group study for a class of non-local interface equations
Nicoli, Matteo; Cuerno Rejado, Rodolfo; Castro Ponce, Mario (2011-10-01)We provide a detailed dynamic renormalization group study for a class of stochastic equations that describe non-conserved interface growth mediated by non-local interactions. We consider explicitly both the morphologically ... -
Generic equations for pattern formation in evolving interfaces
Castro Ponce, Mario; Muñoz García, J.; Cuerno Rejado, Rodolfo; Hernández, M.D.G.; Vázquez Burgos, Luís Fernando (2007-04-01)We present a general formalism which allows us to derive the evolution equations describing one-dimensional (1D) and isotropic 2D interface-like systems, that is based on symmetries, conservation laws, multiple scale ... -

Hydrodynamic approach to surface pattern formation by ion beams
Castro Ponce, Mario; Cuerno Rejado, Rodolfo (2012-02-15)On the proper timescale, amorphous solids can flow. Solid flow can be observed macroscopically in glaciers or lead pipes, but it can also be artificially enhanced by creating defects. Ion Beam Sputtering (IBS) is a technique ... -
Independence of interrupted coarsening on initial system order: ion-beam nanopatterning of amorphous versus crystalline silicon targets
Muñoz García, J.; Gago Fernández, Raúl; Cuerno Rejado, Rodolfo; Sánchez García, José Ángel; Redondo Cubero, Andrés; Castro Ponce, Mario; Vázquez Burgos, Luís Fernando (2012-09-19)Interrupted coarsening (IC) has recently been identified as an important feature for the dynamics of the typical length-scale in pattern-forming systems on surfaces. In practice, it can be beneficial to improve pattern ... -
Interplay between morphology and surface transport in nanopatterns produced by ion-beam sputtering
Cuerno Rejado, Rodolfo; Muñoz García, J.; Castro Ponce, Mario; Gago Fernández, Raúl; Vázquez Burgos, Luís Fernando (2007-12-01)A "hydrodynamic" model has been proposed to describe nanopattern formation and dynamics on amorphous surfaces eroded by ion-beam sputtering (IBS), that relates to descriptions of pattern formation in macroscopic systems ... -
