An intermediate state between the kagome-ice and the fully polarized state in DyTiO
S. A. Grigera, R. Borzi, D. G. Slobinsky +4
DyTiO is at present the cleanest example of a spin-ice material. Previous theoretical and experimental work on the first-order transition between the kagome-ice and the…
Silent Flocks
Andrea Cavagna, Irene Giardina, Tomas S. Grigera +4
Experiments find coherent information transfer through biological groups on length and time scales distinctly below those on which asymptotically correct hydrodynamic theories appl…
Charge ordering in a pure spin model: dipolar spin-ice
R. A. Borzi, D. Slobinsky, S. A. Grigera
We study the dipolar spin-ice model at fixed density of single excitations, , using a Monte Carlo algorithm where processes of creation and annihilation of such excitations are…
Monopole ordered phases in dipolar and nearest-neighbours Ising pyrochlore: from spin ice to the "all-in--all-out" antiferromagnet
Pamela C. Guruciaga, Santiago A. Grigera, Rodolfo A. Borzi
We study Ising pyrochlores by means of Monte Carlo simulations. We cover a set of exchange constants ranging from the frustrated ferromagnetic case (spin-ice) to the fully-ordered…
Flocking and turning: a new model for self-organized collective motion
Andrea Cavagna, Lorenzo Del Castello, Irene Giardina +8
Birds in a flock move in a correlated way, resulting in large polarization of velocities. A good understanding of this collective behavior exists for linear motion of the flock. Ye…
Stochastic Resonance and Dynamic First-Order Pseudo-Phase Transitions in the Irreversible Growth of Thin Films under Spatially Periodic Magnetic Fields
Ernesto S. Loscar, Julián Candia
We study the irreversible growth of magnetic thin films under the influence of spatially periodic fields by means of extensive Monte Carlo simulations. We find first-order pseudo-p…
Superfluid transport of information in turning flocks of starlings
Alessandro Attanasi, Andrea Cavagna, Lorenzo Del Castello +8
Collective decision-making in biological systems requires all individuals in the group to go through a behavioural change of state. During this transition, the efficiency of inform…
Damage Spreading in a Driven Lattice Gas Model
M. Leticia Rubio Puzzo, Gustavo P. Saracco, Ezequiel V. Albano
We studied damage spreading in a Driven Lattice Gas (DLG) model as a function of the temperature , the magnitude of the external driving field , and the lattice size. The DLG…
Short-Time Critical Dynamics of Damage Spreading in the Two-Dimensional Ising Model
M. Leticia Rubio Puzzo, Ezequiel V. Albano
The short-time critical dynamics of propagation of damage in the Ising ferromagnet in two dimensions is studied by means of Monte Carlo simulations. Starting with equilibrium confi…
Ballistic deposition on deterministic fractals: On the observation of discrete scale invariance
Claudio M. Horowitz, Federico Roma, Ezequiel V. Albano
The growth of ballistic aggregates on deterministic fractal substrates is studied by means of numerical simulations. First, we attempt the description of the evolving interface of…
Non-equilibrium Characterization of Spinodal Points using Short Time Dynamics
Ernesto S. Loscar, Ezequiel E. Ferrero, Tomas S. Grigera +1
Though intuitively appealing, the concept of spinodal is rigourously defined only in systems with infinite range interactions (mean field systems). In short-range systems, a pseudo…
The Magnetic Eden Model
Julián Candia, Ezequiel V. Albano
In the magnetic Eden model (MEM), particles have a spin and grow in contact with a thermal bath. Although Ising-like interactions affect the growth dynamics, deposited spins are fr…
On the occurrence of oscillatory modulations in the power-law behavior of dynamic and kinetic processes in fractals
M. A. Bab, G. Fabricius, Ezequiel V. Albano.
The dynamic and kinetic behavior of processes occurring in fractals with spatial discrete scale invariance (DSI) is considered. Spatial DSI implies the existence of a fundamental s…
Interplay between thermal percolation and jamming upon dimer adsorption on binary alloys

Using Monte Carlo simulations we study jamming and percolation processes upon the random sequential adsorption of dimers on binary alloys with different degrees of structural order…
Critical Behaviour of Irreversible Reaction Systems
Ernesto S. Loscar, Ezequiel V. Albano
An introductory review on the critical behaviour of some irreversible reaction systems is given. The study of these systems has attracted great attention during the last decades du…

Fabio Cecconi, Giuseppe Gonnella, Gustavo P. Saracco
We study a model of interacting random walkers that proposes a simple mechanism for the emergence of cooperation in group of individuals. Each individual, represented by a Brownian…
