  We study Bose-Einstein condensation in a harmonic trap with a dimple
potential. We specifically consider the case of a tight and deep dimple
potential which is modelled by a Dirac delta function. This allows for simpler,
explicit numerical and analytical investigations of noninteracting gases. Thus,
the Schrodinger equation is used instead of the Gross-Pitaevski equation.
Calculating the atomic density, chemical potential, critical temperature and
condensate fraction, the role of the relative depth of the dimple potential
with respect to the harmonic trap in large condensate formation at enhanced
temperatures is clearly revealed.
