Abstract: | Here we generalize the results of the work of Myung () in modified Chaplygin gas model and tachyonic field model. Here we have studied the thermodynamical behavior and the equation
of state in terms of volume and temperature for both models. We have used the solution and the corresponding equation of state
of our previous work (Chattopadhyay et al., Astrophys. Space Sci. 314:41, 2008). for tachyonic field model. We have also studied the thermodynamical stability using thermal equation of state for the tachyonic
field model and have shown that there is no critical points during thermodynamical expansion. The determination of T
∗ due to expansion for the tachyonic field have been discussed by assuming some initial conditions. Here, the thermal quantities
have been investigated using some reduced parameters. |
