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…
