Hi Kourosh,
I can't reproduce what you're describing. This is how your examples
look for me. N.B. I don't use any themes or any customization to AUCTeX
fonts:
Maybe you disable any themes (if any) and try it again. For the next
time, please also send some code which can be copy&pasted; it is tedious
to type code. Here the code I used:
--8<---------------cut here---------------start------------->8---
\documentclass[10pt]{article}
\usepackage{amsmath}
\begin{document}
\begin{align}
\label{eq:1}
\Phi(\lambda_1, \lambda_2, \lambda_3) = \sum_{n=1}^N
\frac{\mu_n}{\alpha_n} (\lambda_1 ^ {\alpha_n} + \lambda_2 ^
{\alpha_n} + \lambda_3 ^ {\alpha_n} -3),
\end{align}
increment $t$,
\begin{align}
\label{eq:2}
\matr{\ddot{u}} |_{(t)} = \matr{M} ^ {-1 \cdot (\matr{P} - \matr{I})
|_{(t)}}.
\end{align}
\end{document}
--8<---------------cut here---------------end--------------->8---
Best, Arash
