We consider the planar restricted $N$-body problem where the $N-1$ primaries are assumed to be in a central configuration whereas the infinitesimal p…

An antimagic labeling a connected graph $G$ is a bijection from the set of edges $E(G)$ to $\{1,2,\dots,|E(G)|\}$ such that all vertex sums are pairw…

We study the free diffusion in two dimensions of active-Brownian swimmers subject to passive fluctuations on the translational motion and to active f…

We presented the different analogies existing between the solution to the Klein–Gordon equation with the solution to the Gross–Pitaevskii equation.

We discuss the analogy between a classical scalar field with a self-interacting potential, in a curved spacetime described by a quasi--bounded state,…

A new coordinate system is defined for the Four-Body dynamical problem with general masses, having as its origin of coordinates the center of mass. T…

Families of alternating knots (links) and tangles are studied using as building block the conway defined as the twisting of two strands. The regular …

This work was partially supported by CONACyT Grant No. 237351 “Implicaciones físicas de la estructura del espacio tiempo” and DGAPA-UNAM Grant No. IN113115 “Teoría de campos en fondos curvos, gravedad cuántica y holografía”.

The success of loop quantum cosmology to resolve classical singularities of homogeneous models has led to its application to the classical Schwarszch…

Polymer quantum systems are mechanical models quantized similarly as loop quantum gravity. It is actually in quantizing gravity that the polymer term…

A complete solution describing a binary system constituted by two unequal counter-rotating black holes with a massless strut inbetween is presented. …

The alternating knots, links and twists projected on the $S_2$ sphere were identified with the phase space of a Hamiltonian dynamic system of one deg…

We propose a new flexible force field for water. The model in addition to the Lennard-Jones and electrostatic parameters, includes the flexibility of…

An algorithm to compute the six distances between particles of a planar Four-Body central configuration is presented according to the following schem…

Elements of the general theory of potential curves for diatomic molecules are presented. For the diatomic molecule He$_2^+$ in Born-Oppenheimer (BO) …

The relativistic equilibrium velocity distribution plays a key role in describing several high-energy and astrophysical effects. Recently, computer s…

Braneworld models may yield interesting effects ranging from high-energy physics to cosmology, or even some low-energy physics. Their mode structure …

Recent developments in speech synthesis have produced systems capable of outcome intelligible speech, but now researchers strive to create models tha…

The authors would like to thank D. Grumiller for his enlightening comments on [8]. They would also like to acknowledge the partial support of CONACyT grant 237351: Implicaciones Físicas de la Estructura del Espaciotiempo. S.R. would like to acknowle…

The saddle point approximation to the partition functions is an important way of deriving the thermodynamical properties of black holes. However, the…

In this work, we have laid out the basis of a novel approach to the emergence of smooth spacetime from a discrete substratum based on purely geometric notions. The approach resembles the Wilsonian renormalization procedure. The starting point or the…

We present a purely geometric renormalization scheme for metric spaces (including uncolored graphs), which consists of a coarse graining and a rescal…

Waveguides have been successfully used to generate magnetic resonance images at 7 T with whole-body systems. The bore limits the magnetic resonance s…

It is shown that the non-relativistic ground state energy of helium-like and lithium-like ions with static nuclei can be easily interpolated in full …
