Cluster Monte Carlo and dynamical scaling for long-range interactions
Emilio Flores-Sola, Martin Weigel, Ralph Kenna +1
Many spin systems affected by critical slowing down can be efficiently simulated using cluster algorithms. Where such systems have long-range interactions, suitable formulations ca…
Ferromagnetic order induced on graphene by Ni/Co proximity effects
Mayra Peralta, Luis Colmenarez, Alejandro López +2
We build a tight-binding Hamiltonian describing Co/Ni over graphene, contemplating ATOP (a Co/Ni atom on top of each Carbon atom of one graphene sublattice) and HCP (one Co/Ni atom…
Modeling Kleinian cosmology with electronic metamaterials
David Figueiredo, Felipe Azevedo Gomes, Sébastien Fumeron +2
This paper deals with the propagation of Klein-Gordon particles in flat background spacetime exhibiting discontinuous metric changes from a Lorentzian signature (-,+,+,+) to a Klei…
Gauge transformations and conserved quantities in classical and quantum mechanics
Bertrand Berche, Daniel Malterre, Ernesto Medina
We are taught that gauge transformations in classical and quantum mechanics do not change the physics of the problem. Nevertheless here we discuss three broad scenarios where under…
Universal Finite-Size Scaling for Percolation Theory in High Dimensions
Ralph Kenna, Bertrand Berche
We present a unifying, consistent, finite-size-scaling picture for percolation theory bringing it into the framework of a general, renormalization-group-based, scaling scheme for s…
Propagation of acoustic waves in a von-Kármán vortex street like configuration of disclinations
Sébastien Fumeron, Bertrand Berche, Fernando Moraes +2
We show that a simple model of 1D array of topological defects in a crystalline environment is able to guide acoustic waves, depending on the angle of the incident wave. We comment…
