$\displaystyle \beta=\frac{1}{\tau}=\frac{1}{k_{\text{B}}T}=\frac{ \partial \sigma }{ \partial E }$
- $\displaystyle \tau$ is the [fundamental temperature]
- $\displaystyle T$ is temperature
- $\displaystyle k_{B}$ is the [Boltzmann constant]
- $\displaystyle U$ is the total energy of the system and environment
