Activity of order n in continuous systems
(Sage Publications, 2015-04)
In this work we generalize the concept of activity of continuous time signals. We define the activity of order n of a signal and show that it allows us to estimate the number of sections of polynomials up to order n which ...
Simulación eficiente de sistemas rígidos y conmutados
(2019-03-21)
Las imágenes por resonancia magnética (MRI por sus siglas en inglés) se han constituido como una tecnología que permite estudiar múltiples características de los tejidos in-vivo. En el estudio del cerebro, permiten describir ...
Coulomb integrals and conformal blocks in the AdS3-WZNW model
(IOP Publishing, 2009-11)
We study spectral flow preserving four-point correlation functions in the AdS3- WZNW model using the Coulomb gas method on the sphere. We present a multiple integral realization of the conformal blocks and explicitly ...
Quasi-probability distributions for the simplest dynamical groups
(2005)
We show that any pure, two-mode, N-photon state with N odd or equal to two can be transformed into an orthogonal state using only linear optics. According to a recently suggested definition of polarization degree, this ...
