On Padmanabhan's duality invariance and the quantum of length
P. Fernandez de Cordoba, J. M. Isidro, A. Pereira Garcia
We provide a field-theoretic construction of Padmanabhan's duality-invariant Feynman propagator for a massive point particle in Euclidean space . Padmanabhan's propag…
Thermality of the zero-point length and gravitational selfduality
P. Fernandez de Cordoba, J. M. Isidro, Rudranil Roy
It has been argued that the existence of a zero-point length is the hallmark of quantum gravity. In this letter we suggest a thermal mechanism whereby this quantum of length arises…
Spacetime metric from quantum-gravity corrected Feynman propagators
P. Fernandez de Cordoba, J. M. Isidro, Rudranil Roy
Differentiation of the scalar Feynman propagator with respect to the spacetime coordinates yields the metric on the background spacetime that the scalar particle propagates in. Now…
Spherical space in the Newtonian limit: The cosmological constant
J. M. Isidro, P. Fernandez de Cordoba, J. C. Castro-Palacio
We compute the cosmological constant of a spherical space in the limit of weak gravity. To this end we use a duality developed by the present authors in a previous work. This duali…
Machinery Failure Approach and Spectral Analysis to study the Reaction Time Dynamics over Consecutive Visual Stimuli
M. E. Iglesias-Martínez, M. Hernaiz-Guijarro, J. C. Castro-Palacio +3
The reaction times of individuals over consecutive visual stimuli have been studied using spectral analysis and a failure machinery approach. The used tools include the fast Fourie…
The cosmological constant of emergent spacetime in the Newtonian approximation
J. C. Castro-Palacio, P. Fernandez de Cordoba, J. M. Isidro
We present a simple quantum-mechanical estimate of the cosmological constant of a Newtonian Universe. We first mimic the dynamics of a Newtonian spacetime by means of a nonrelativi…
