String theory phenomenology and quantum many body systems
Sergio Gutiérrez, Abel Camacho, Héctor Hernández
The main idea in the present work is the definition of an experimental proposal for the detection of the number of extra{compact dimensions contained as a core feature in String Th…
Mass bounds for Newtonian bosonic starts in theory of ultra-cold gases
Sergio Gutiérrez, Belen Carvente, Abel Camacho
In the present work we address the issue concerning the relation mass versus radius for bosonic stars, all this in the context of the theory of ultra-cold gases in the dilute regim…
Superfluidity as a Tool for Constraining Energy-Momentum Relations
Abel Camacho, Sergio Gutiérrez
The present work explores the possibilities that superfluidity could offer in the context of quantum gravity phenomenology, at least in the realm of deformed dispersion relations.…
Quantum spacetime fluctuations: Lamb Shift and hyperfine structure of the hydrogen atom
Juan Israel Rivas, Abel Camacho, Ertan Goeklue
We consider the consequences of the presence of metric fluctuations upon the properties of a hydrogen atom. Particularly, we introduce these metric fluctuations in the correspondin…
Space--time fluctuations and the spreading of wavepackets
E. Göklü, C. Lämmerzahl, A. Camacho +1
Using a density matrix description in space we study the evolution of wavepackets in a fluctuating space-time background. We assume that space-time fluctuations manifest as classic…
Quantal Definition of the Weak Equivalence Principle
Abel Camacho, Arturo Camacho-Guardian
The present work analyzes the meaning of the Weak Equivalence Principle in the context of quantum mechanics. A quantal definition for this principle is introduced. This definition…
Test of some Fundamental Principles in Physics via Quantum Interference with Neutrons and Photons
Abel Camacho, Abel Camacho-Galvan
The limitations and possibilities that the concept of quantum interference offers as a tool for testing fundamental physics are explored here. The use of neutron interference as an…
Critical points in a relativistic bosonic gas induced by the quantum structure of spacetime
Elias Castellanos, Abel Camacho
It is well known that phase transitions arise if the interaction among particles embodies an attractive as well as a repulsive contribution. In this work it will be shown that the…
Midisuperspace Supersymmetric Quantum Cosmology
Alfredo Macias, Abel Camacho, Jutta Kunz +1
We investigate the canonical quantization in the framework of N=1 simple supergravity for the case of a very simple gravitational midisuperspace described by Gowdy cosmologic…
Thermodynamics of a photon gas and deformed dispersion relations
A. Camacho, A. Macias
We resort to the methods of statistical mechanics in order to determine the effects that a deformed dispersion relation has upon the thermodynamics of a photon gas. The ensuing mod…
White dwarfs as test objects of Lorentz violations
Abel Camacho
In the present work the thermodynamical properties of bosonic and fermionic gases are analyzed under the condition that a modified dispersion relation is present. This last conditi…
Deformed dispersion relations and the degree of coherence function
A. Camacho, A. Macias
The analysis of the modifications that the presence of a deformed dispersion relation entails in the roots of the so--called degree of coherence function, for a beam embodying two…
Continuous distribution of frequencies and deformed dispersion relations
Abel Camacho
The possibilities that, in the realm of the detection of the so--called deformed dispersion relation, a light source with a continuous distribution of frequencies offers is discuss…

In the present work we analyze the possibility of detecting some deformed dispersion relations, emerging in some quantum--gravity models, resorting to the so--called Hanbury--Brown…
Sagnac interferometry and non-Newtonian gravity
Abel Camacho, Abel Camacho-Galvan
Sagnac interferometry has been employed in the context of gravity as a proposal for the detection of the so called gravitomagnetic effect. In the present work we explore the possib…
