The importance of selection rate in the evolution of cooperation
Carlos P. Roca, Jose A. Cuesta, Angel Sanchez
How cooperation emerges in human societies is still a puzzle. Evolutionary game theory has been the standard framework to address this issue. In most models, every individual plays…
Electrostatic models for zeros of polynomials: old, new, and some open problems
F. Marcellan, A. Martinez-Finkelshtein, P. Martinez-Gonzalez
We give a survey concerning both very classical and recent results on the electrostatic interpretation of the zeros of some well-known families of polynomials, and the interplay be…
From zero resistance states to absolute negative conductivity in microwave irradiated 2D electron systems
J. Inarrea, G. Platero
Recent experimental results regarding a 2D electron gas subjected to microwave radiation reveal that magnetoresistivity, apart from presenting oscillations and zero resistance stat…
Soliton ratchets in homogeneous nonlinear Klein-Gordon systems
Luis Morales-Molina, Niurka R. Quintero, Franz G. Mertens +1
We study in detail the ratchet-like dynamics of topological solitons in homogeneous nonlinear Klein-Gordon systems driven by a bi-harmonic force. By using a collective coordinate a…
On the discrete Peyrard-Bishop model of DNA: stationary solutions and stability
Sara Cuenda, Angel Sanchez
As a first step in the search of an analytical study of mechanical denaturation of DNA in terms of the sequence, we study stable, stationary solutions in the discrete, finite and h…
Interactions and disorder in 2D graphite sheets
Francisco Guinea, M. Pilar Lopez-Sancho, Maria A. H. Vozmediano
The present work discusses theoretical models which address the effects of electron--electron interactions and disorder in graphene planes. The starting point for the study is a si…
Modelling Disorder: the Cases of Wetting and DNA Denaturation
Saul Ares, Angel Sanchez
We study the effect of the composition of the genetic sequence on the melting temperature of double stranded DNA, using some simple analytically solvable models proposed in the fra…
Complex-temperature phase diagram of Potts and RSOS models
Jesper Lykke Jacobsen, Jean-Francois Richard, Jesus Salas
We study the phase diagram of Q-state Potts models, for Q=4 cos^2(PI/p) a Beraha number (p>2 integer), in the complex-temperature plane. The models are defined on L x N strips of t…
Fourier-Padé approximants for Angelesco systems
M. Bello-Hernández, G. López-Lagimasino, J. Mínguez-Ceniceros
In this paper we study linear and non-linear Fourier-Padé approximation for Angelesco systems of functions. This construction is similar to that of Hermite-Padé approximation. Inst…
Temperature effects on microwave-induced resistivity oscillations and zero resistance states in 2D electron systems
J. Iñarrea, G. Platero
In this work we address theoretically a key issue concerning microwave-induced longitudinal resistivity oscillations and zero resistance states, as is tempoerature. In order to exp…
Non-negativity preserving numerical algorithms for stochastic differential equations
Esteban Moro, Henri Schurz
Construction of splitting-step methods and properties of related non-negativity and boundary preserving numerical algorithms for solving stochastic differential equations (SDEs) of…
Spreading of thin films assisted by thermal fluctuations
Benny Davidovitch, Esteban Moro, Howard A. Stone
We study the spreading of viscous drops on a solid substrate, taking into account the effects of thermal fluctuations in the fluid momentum. A nonlinear stochastic lubrication equa…
Stability of smectic phases in hard-rod mixtures
Yuri Martinez-Raton, Enrique Velasco, Luis Mederos
Using density-functional theory, we have analyzed the phase behavior of binary mixtures of hard rods of different lengths and diameters. Previous studies have shown a strong tenden…
Demixing behavior in two-dimensional mixtures of anisotropic hard bodies
Yuri Martinez-Raton, Enrique Velasco, Luis Mederos
Scaled particle theory for a binary mixture of hard discorectangles and for a binary mixture of hard rectangles is used to predict possible liquid-crystal demixing scenarios in two…
Inhomogeneous soliton ratchets under two ac forces
Luis Morales-Molina, Franz G. Mertens, Angel Sanchez
We extend our previous work on soliton ratchet devices [L. Morales-Molina et al., Eur. Phys. J. B 37, 79 (2004)] to consider the joint effect of two ac forces including non-harmoni…
Self-Organized Ordering of Nanostructures Produced by Ion-Beam Sputtering
Mario Castro, Rodolfo Cuerno, Luiz Vazquez +1
We study the self-organized ordering of nanostructures produced by ion-beam sputtering (IBS) of targets amorphizing under irradiation. By introducing a model akin to models of patt…
Moduli Spaces for Principal Bundles in Arbitrary Characteristic
T. L. G'omez, A. Langer, A. H. W. Schmitt +1
In this article, we solve the problem of constructing moduli spaces of semistable principal bundles (and singular versions of them) over smooth projective varieties over algebraica…
Non-linear ripple dynamics on amorphous surfaces patterned by ion-beam sputtering
Javier Muñoz-García, Mario Castro, Rodolfo Cuerno
Erosion by ion-beam sputtering (IBS) of amorphous targets at off-normal incidence frequently produces a (nanometric) rippled surface pattern, strongly resembling macroscopic ripple…
Local defects and ferromagnetism in graphene layers
M. A. H. Vozmediano, M. P. Lopez-Sancho, T. Stauber +1
We study the changes in the electronic structure induced by lattice defects in graphene planes. In many cases, lattice distortions give rise to localized states at the Fermi level.…
Complex Networks as Hypergraphs
Ernesto Estrada, Juan A. Rodriguez-Velazquez
The representation of complex systems as networks is inappropriate for the study of certain problems. We show several examples of social, biological, ecological and technological s…
Subgraph Centrality in Complex Networks
Ernesto Estrada, Juan A. Rodriguez-Velazquez
We introduce a new centrality measure that characterizes the participation of each node in all subgraphs in a network. Smaller subgraphs are given more weight than larger ones, whi…
Spectral Measures of Bipartivity in Complex Networks
Ernesto Estrada, Juan A. Rodriguez-Velazquez
We introduce a quantitative measure of network bipartivity as a proportion of even to total number of closed walks in the network. Spectral graph theory is used to quantify how clo…
Lattice density functional for colloid-polymer mixtures: Multi-occupancy versus Highlander version
Jose A. Cuesta, Luis Lafuente, Matthias Schmidt
We consider a binary mixture of colloid and polymer particles with positions on a simple cubic lattice. Colloids exclude both colloids and polymers from nearest neighbor sites. Pol…
Cluster density functional theory for lattice models based on the theory of Mobius functions
Luis Lafuente, Jose A. Cuesta
Rosenfeld's fundamental measure theory for lattice models is given a rigorous formulation in terms of the theory of Mobius functions of partially ordered sets. The free-energy dens…
