Vacancy Effect on the Ground-State Energy of a Bose Gas Trapped by 1D Imperfect Artificial Crystal
E. I. Guerrero-Cruz, O. A. Rodríguez-López, M. A. Solís
For a weakly interacting Bose gas trapped by an imperfect one-dimensional artificial crystal, we study the effect of its punctual defects, i.e. vacancies, on the ground state prope…

I. Chávez, P. Salas, M. A. Solís +1
A detailed analysis is given of the effects of common and recurring approximations used in conventional superconductivity theories on the condensation energy values, whose magnitud…
Performance of Deep Learning models with transfer learning for multiple-step-ahead forecasts in monthly time series
Martín Solís, Luis-Alexander Calvo-Valverde
Deep Learning and transfer learning models are being used to generate time series forecasts; however, there is scarce evidence about their performance prediction that it is more ev…
