We develop a FORTRAN code to compute fluctuations in atomic condensates (FACt) by solving the Bogoliubov-de Gennes (BdG) equations for two component Bose-Einstein condensate (TBEC) in quasi two dimensions. The BdG equations are recast as matrix equations and solved self consistently. The code is suitable for handling quantum fluctuations as well as...

... finite temperature computations, solving the HFB-Popov equations require it- erations and we consider ITMAX = 15 for all the finite temperature computations reported in this work. The density profiles of n ic corresponding to each HFB-Popov iterations are stored in the file den00x.dat where x runs from 0 to ITMAX. When T = 0, at each iteration, the number of condensate atoms decreases, whereas the number of thermal (non condensate) atoms increases. Fig. 5 shows the equilibrium profiles of n ic and?and?and? ic for three different temperatures in miscible domain. The plots in Fig. 5(a) correspond to n ic at T = 0nK, and hence in Fig.5(d) ? n ic are negligibly small. The plots in Fig. 5(b) and (c) correspond to n ic at T = 5nK and T = 10nK, respectively. To obtain the plots in the top row, we plotted column 1, column 3 and column 5 file of den00x.dat with column 3 and column 5 multiplied by number of condensate atoms N 01 and N 02 (taken from hfb2d2s.out), respectively. Although, the changes in n ic are not dramatic, there is a large change i? n ic as shown in Fig.5(e)- (f). From Fig. 5, there is a notable feature of?of?of? ic : it has a minimum where n ic has maximum value. For the side by side configuration the density profiles at finite temperature are shown in Fig. 6. Like in the miscible domain, here as well, we observe growth i?i? n ic with the increase of temperature and thereby lowering the number of condensate atoms. It is to be noted that at the interface of two species, where the n ic are low, ? n ic have maximum value. ...
