Relativistic Lévy processes
Lucas G. B. de Souza, M. G. E. da Luz, E. P. Raposo +2
We study sums of independent and identically distributed random velocities in special relativity. We show that the resulting one-dimensional velocity distributions are not only sta…
Lattice Thermal Conductivity of 2D Nanomaterials: A Simple Semi-Empirical Approach
R. M. Tromer, I. M. Felix, L. F. C. Pereira +3
Extracting reliable information on certain physical properties of materials, like thermal behavior, such as thermal transport, which can be very computationally demanding. Aiming t…
Asymmetric space-dependent systems: Partial stabilization through the addition of noise and exact solutions for the corresponding nonlinear Langevin equations
K. S. Fa, C. -L. Ho, Y. B. Matos +1
In many instances, the dynamical richness and complexity observed in natural phenomena can be related to stochastic drives influencing their temporal evolution. For example, random…
What does it take to solve the 3D Ising model? Minimal necessary conditions for a valid solution
G. M. Viswanathan, M. A. G. Portillo, E. P. Raposo +1
Exact solution of the Ising model on the simple cubic lattice is one of the long-standing open problems in rigorous statistical mechanics. Indeed, it is generally believed that set…
Threshold-free estimation of entropy from a Pearson matrix
H. Felippe, A. Viol, D. B. de Araujo +5
There is demand in diverse fields for a reliable method of estimating the entropy associated with correlations. The estimation of a unique entropy directly from the Pearson correla…
Finite-size scaling for discontinuous nonequilibrium phase transitions
Marcelo M. de Oliveira, M. G. E. da Luz, Carlos E. Fiore
A finite size scaling theory, originally developed only for transitions to absorbing states [Phys. Rev. E {\bf 92}, 062126 (2015)], is extended to distinct sorts of discontinuous n…
Green's function approach for quantum graphs: an overview
Fabiano M. Andrade, A. G. M. Schmidt, E. Vicentini +2
Here we review the many aspects and distinct phenomena associated to quantum dynamics on general graph structures. For so, we discuss such class of systems under the energy domain…
Generic finite size scaling for discontinuous nonequilibrium phase transitions into absorbing states
M. M. de Oliveira, M. G. E. da Luz, C. E. Fiore
Based on quasi-stationary distribution ideas, a general finite size scaling theory is proposed for discontinuous nonequilibrium phase transitions into absorbing states. Analogously…
Determining efficient temperature sets for the simulated tempering method
A. Valentim, M. G. E. da Luz, Carlos E. Fiore
In statistical physics, the efficiency of tempering approaches strongly depends on ingredients such as the number of replicas , reliable determination of weight factors and the…
Exploiting a semi-analytic approach to study first order phase transitions
Carlos. E. Fiore, M. G. E. da Luz
In a previous contribution, Phys. Rev. Lett 107, 230601 (2011), we have proposed a method to treat first order phase transitions at low temperatures. It describes arbitrary order p…
Green function approach for scattering quantum walks
F. M. Andrade, M. G. E. da Luz
In this work a Green function approach for scattering quantum walks is developed. The exact formula has the form of a sum over paths and always can be cast into a closed analytic e…

C. E. Fiore, M. G. E. da Luz
By combining different ideas, a general and efficient protocol to deal with discontinuous phase transitions at low temperatures is proposed. For small 's, it is possible to deri…
A simple protocol for the probability weights of the simulated tempering algorithm: applications to first-order phase transitions
Carlos E. Fiore, M. G. E. da Luz
The simulated tempering (ST) is an important method to deal with systems whose phase spaces are hard to sample ergodically. However, it uses accepting probabilities weights which o…
Equivalence between discrete quantum walk models in arbitrary topologies
F. M. Andrade, M. G. E. da Luz
Coin and scattering are the two major formulations for discrete quantum walks models, each believed to have its own advantages in different applications. Although they are related…
Average Time Spent by Levy Flights and Walks on an Interval with Absorbing Boundaries
S. V. Buldyrev, S. Havlin, A. Ya. Kazakov +4
We consider a Levy flyer of order alpha that starts from a point x0 on an interval [O,L] with absorbing boundaries. We find a closed-form expression for the average number of fligh…
