Geometric Constraints on Quantum Gravity-Inspired Dispersion Relations
Gines R. Perez Teruel
Modified dispersion relations (MDRs) arise in many quantum-gravity approaches, often in non-polynomial or non-analytic form beyond the reach of effective field theory (EFT). Logari…
A Modified Gravitational Theory of the Matter Sector of the Type
Gines R. Pérez Teruel, Antonio Peña Peña
We investigate a modified gravity framework where the geometric Einstein--Hilbert sector remains untouched while the matter Lagrangian is weighted by a nontrivial function o…
Cause-effect relationships in Maxwell's equations and their implications in the teaching of electromagnetism in introductory physics courses
Alvaro Suarez, Arturo C. Marti, Kristina Zuza +1
A thoughtless treatment of Maxwell's equations can lead to the interpretation of the existence of a causal relationship between their different terms and, therefore, that an electr…
A dynamical model of remote-control model cars
Álvaro Suárez, Daniel Baccino, Arturo C Martí
Simple experiments for which differential equations cannot be solved analytically can be addressed using an effective model that satisfactorily reproduces the experimental data. In…
