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…
Symmetry pattern transition in cellular automata with complex behavior
J. R. Sanchez, R. Lopez-Ruiz
A transition from asymmetric to symmetric patterns in time-dependent extended systems is described. It is found that one dimensional cellular automata, started from fully random in…
Explicit factorization of external coordinates in constrained Statistical Mechanics models
Pablo Echenique, Ivan Calvo
If a macromolecule is described by curvilinear coordinates or rigid constraints are imposed, the equilibrium probability density that must be sampled in Monte Carlo simulations inc…
Transport in chaotic quantum dots: effects of spatial symmetries which interchange the leads
Victor A. Gopar, Stefan Rotter, Henning Schomerus
We investigate the effect of spatial symmetries on phase coherent electronic transport through chaotic quantum dots. For systems which have a spatial symmetry that interchanges the…
Phase transition in the assignment problem for random matrices
J. G. Esteve, F. Falceto
We report an analytic and numerical study of a phase transition in a P problem (the assignment problem) that separates two phases whose representatives are the simple matching prob…
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…
Definition of Systematic, Approximately Separable and Modular Internal Coordinates (SASMIC) for macromolecular simulation
Pablo Echenique, J. L. Alonso
A set of rules is defined to systematically number the groups and the atoms of organic molecules and, particularly, of polypeptides in a modular manner. Supported by this numeratio…
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…
Numerical Simulations of Random Phase Sine-Gordon Model and Renormalization Group Predictions
D. J. Lancaster, J. J. Ruiz-Lorenzo
Numerical Simulations of the random phase sine-Gordon model suffer from strong finite size effects preventing the non-Gaussian component of the spatial correlator from f…
Statistical study of the conductance and shot noise in open quantum-chaotic cavities: Contribution from whispering gallery modes
Evgeny N. Bulgakov, Victor A. Gopar, Pier A. Mello +1
In the past, a maximum-entropy model was introduced and applied to the study of statistical scattering by chaotic cavities, when short paths may play an important role in the scatt…
Symmetry and environment effects on rectification mechanisms in quantum pumps
Liliana Arrachea
We consider a paradigmatic model of quantum pumps and discuss its rectification properties in the framework of a symmetry analysis proposed for ratchet systems. We discuss the role…
Can one predict DNA Transcription Start Sites by studying bubbles?
Titus S. van Erp, Santiago Cuesta-Lopez, Johannes-Geert Hagmann +1
It has been speculated that bubble formation of several base-pairs due to thermal fluctuations is indicatory for biological active sites. Recent evidence, based on experiments and…
A Model of Coupled-Maps for Economic Dynamics
J. R. Sanchez, R. Lopez-Ruiz
An array system of coupled maps is proposed as a model for economy evolution. The local dynamics of each map or agent is controlled by two parameters. One of them represents the gr…
Numerical study of the enlarged O(5) symmetry of the 3-D antiferromagnetic RP2 spin model
L. A. Fernandez, V. Martin-Mayor, D. Sciretti +2
We investigate by means of Monte Carlo simulation and Finite-Size Scaling analysis the critical properties of the three dimensional O(5) non linear sigma model and of the antiferro…
A way to synchronize models with seismic faults for earthquake forecasting: Insights from a simple stochastic model
Alvaro Gonzalez, Miguel Vazquez-Prada, Javier B. Gomez +1
Numerical models are starting to be used for determining the future behaviour of seismic faults and fault networks. Their final goal would be to forecast future large earthquakes.…
Quantum Monte Carlo method for models of molecular nanodevices
Liliana Arrachea, Marcelo J. Rozenberg
We introduce a quantum Monte Carlo technique to calculate exactly at finite temperatures the Green function of a fermionic quantum impurity coupled to a bosonic field. While the al…
A Green-function approach to transport phenomena in quantum pumps
Liliana Arrachea
We present a general treatment to study transport phenomena in systems described by tight-binding Hamiltonians coupled to reservoirs and with one or more time-periodic potentials.…
Order in Binary Sequences and the Routes to Chaos
Ricardo Lopez-Ruiz
The natural order in the space of binary sequences permits to recover the -sequence. Also the scaling laws of the period-doubling cascade and the intermittency route to chaos de…
A physically meaningful method for the comparison of potential energy functions
J. L. Alonso, Pablo Echenique
In the study of the conformational behavior of complex systems, such as proteins, several related statistical measures are commonly used to compare two different potential energy f…
On the critical behavior of the specific heat in glass-formers
L. A. Fernandez, V. Martin-Mayor, P. Verrocchio
We show numeric evidence that, at low enough temperatures, the potential energy density of a glass-forming liquid fluctuates over length scales much larger than the interaction ran…
The occupation of a box as a toy model for the seismic cycle of a fault
Alvaro Gonzalez, Javier B. Gomez, Amalio F. Pacheco
We illustrate how a simple statistical model can describe the quasiperiodic occurrence of large earthquakes. The model idealizes the loading of elastic energy in a seismic fault by…
