The kinetic model of opinion formation by Deffuant-Neau-Amblard-Weisbush (DNAW), one of the most well-known in sociophysics, describes the process of opinion formation towards consensus or homogeneous opinions. This is done by considering exchanges of opinion between pairs of agents, in such a way that these exchanges have limited influence as they are confined within a range of opinion and...
The distribution by regions of electoral voting is frequently studied in the sociopolitical field. Making use of the databases on presidential and congressional voting reported by the Registraduria NAcional del Estado Civil (RNEC) in Colombia, by the Servicio Electoral de Chile (SERVEL) and by the Instituto Nacional Electoral (INE) in Mexico, it is found that the votes obtained in properly...
Most stochastic processes are solved by knowing the probability distribution of the process increments or the transition probability distribution that satisfies a Fokker-Planck equation. Also, a rather interesting and known application of stochastic processes is in the Feynman-Kac formula, which presents the equivalence of parabolic partial differential equation problems and stochastic...
In this paper, we explore the reduction of functionality in a complex system as a consequence of cumulative random damage and imperfect reparation, a phenomenon modeled as a dynamical process on networks. We analyze the global characteristics of the diffusive movement of random walkers on networks where the walkers hop considering the capacity of transport of each link. The links are...
When a system deviates from equilibrium, it is possible to manipulate and control it to drive it towards equilibrium within a finite time $t_f$, even reducing its natural relaxation time scale $\tau_{relax}$. Although numerous theoretical and experimental studies have explored these shortcut protocols, few have yielded analytical results for the probability distribution of work, heat and...
In this work, the ferromagnetic phase transition in a monolayer of chromium triiodide (CrI3) was examined. Employing a microcanonical ensemble approach, entropy was evaluated as a function of internal energy and magnetization was calculated with respect to energy across various spin configurations. In this way, a methodology was found to observe phase transitions using thermodynamic quantities...
Using the mean-field renormalization group method (MFRG) and starting from the Ising Hamiltonian, magnetic phase diagrams were successfully reproduced in various systems composed of different types of magnetic atoms, such as FeMnAl, FeNiMn, and FeAl alloys. Quadratic errors we obtained below 0.016, and a preliminary approximation of the binding energy between atoms of this type was achieved....
An important task in quantum thermodynamics consists of the characterization of work and heat in the quantum domain. A common approach to this problem, known as the two-point measurement (TPM) scheme, consists of performing two projective energy measurements at the beginning and at the end of a given evolution protocol. Although its importance for the development of the understanding of work...
We study the non-equilibrium dynamics for no-fusion and fusion events in a Dyson gas of $N$ charged particles interacting through a logarithmic Coulomb potential surrounded by a thermal bath at a reduced temperature $\beta=q_0^2/(k_BT)$, where $q_0$ is the charge per particle and $T$ is temperature of the bath. First, we characterize the relaxation-time, $\tau$, in the regime for no-fusion...
In the conventional quantum mechanics of conserved systems, Hamiltonian is assumed to be a Hermitian operator. However, when it comes to quantum systems in presence of dissipation and/or noise, including open quantum optical systems, the strict hermiticity requirement is no longer necessary. In fact, it can be substantially relaxed: the non-Hermitian part of a Hamiltonian is allowed, in order...
