\section{Mixed Modes}
Acoustic waves (p-modes) excited by turbulent convection in red giant envelopes can couple to internal gravity waves. This is because, as a red giant increase its radius, the frequency $\omega$ of p-modes decreases and becomes comparable to the frequency of waves in the g-mode cavity. In this situation some of the energy in the p-modes can leak into the g-modes cavity, where waves with frequency $\omega < N$ can be excited ($N$ is the Brunt-Vaisala frequency). These pulsation modes, called mixed-modes, are characterized by significant displacements in both the envelope and the core of a red giant. Their particular nature has enabled important asteroseismic discoveries, in particular the ability to distinguish He-burning clump stars from red giant stars burning hydrogen in a shell \cite{Bedding_2011}, as well as the measurement of core-envelope differential rotation in RGB stars \cite{Beck_2011}.
\begin{itemize}
\item Excitation of stochastically excited p-modes
\item Coupling to g-modes
\item Canonical Damping mechanisms (radiative damping) \cite{Dupret_2009}
\item Tunneling and evolution of tunneling integral for l=1,2
\end{itemize}
\subsection{Tunneling Integral}
The radial displacement
\begin{equation}
\label{eqn:dr}
k_r^2=\Bigg( 1 - \frac{N^2}{\omega^2}\Bigg) \Bigg(1 - \frac{S_\ell^2}{\omega^2}\Bigg)\,\frac{\omega^2}{c_s^2}
\end{equation}
Here, $\omega$ is the angular frequency of the wave, $N$ is the Brunt-Vaisala frequency, $S_\ell$ is the Lamb frequency for waves with harmonic degree $\ell$ and $c_s$ is the sound speed.
