Beyond Dunbar circles: a continuous description of social relationships and resource allocation
Ignacio Tamarit, Angel Sánchez, José A. Cuesta
We discuss the structure of human relationship patterns in terms of a new formalism that allows to study resource allocation problems where the cost of the resource may take contin…
Paid and hypothetical time preferences are the same: Lab, field and online evidence
Pablo Brañas-Garza, Diego Jorrat, Antonio M. Espín +1
The use of hypothetical instead of real decision-making incentives remains under debate after decades of economic experiments. Standard incentivized experiments involve substantial…
The emergence of segregation: from observable markers to group specific norms
Juan Ozaita, Andrea Baronchelli, Angel Sánchez
Observable social traits determine how we interact in society and remain pervasive even in our globalized world. While a popular hypothesis states that they may help promote cooper…
Kicks of magnetized strange quark stars induced by anisotropic emission of neutrinos
Alejandro Ayala, D. Manreza Paret, A. Pérez Martínez +3
We study the anisotropic neutrino emission from the core of neutron stars induced by the star's magnetic field. We model the core as made out of a magnetized ideal gas of strange q…
More network science for teenagers
Angel Sánchez, Cristina Brändle
Recently, Harrington et al.\ (2013) presented an outreach effort to introduce school students to network science and explain why researchers who study networks should be involved i…
Chiral phase transition in relativistic heavy-ion collisions with weak magnetic fields: ring diagrams in the linear sigma model
Alejandro Ayala, Adnan Bashir, Alfredo Raya +1
Working in the linear sigma model with quarks, we compute the finite-temperature effective potential in the presence of a weak magnetic field, including the contribution of the pio…
Effective potential at finite temperature in a constant magnetic field I: Ring diagrams in a scalar theory
Alejandro Ayala, Angel Sánchez, Gabriella Piccinelli +1
We study symmetry restoration at finite temperature in the theory of a charged scalar field interacting with a constant, external magnetic field. We compute the finite temperature…
Lattice model for kinetics and grain size distribution in crystallization
Mario Castro, Angel Sánchez, Francisco Domínguez-Adame
We propose a simple, versatile and fast computational model tounderstand the deviations from the well-known Kolmogorov-Johnson-Mehl-Avrami kinetic theoryfound in metal recrystalliz…
DC motion of ac driven sine-Gordon solitons
Niurka R. Quintero, Angel Sánchez
We investigate the possibility of dc soliton motion sustained by pure ac driving in the sine-Gordon model. We show by means of the collective coordinate formalism that ac driving i…
Nonlinear Resonant Tunnelling Through Double Barrier Structures
Enrique Diez, Francisco Dominguez-Adame, Angel Sánchez
We study resonant tunnelling through double-barrier structures under an applied bias voltage, in which nonlinearities due to self-interaction of electrons in the barrier regions ar…
