Parameter: mfreq

Definition

Maximum number of Matsubara frequency points $n_{\text{max}}$. The Matsubara frequency mesh for fermions is defined as follows:

$$\omega_n = \frac{(2n + 1)\pi}{\beta}$$

where $n$ = 0, 1, 2, 3, $\cdots$, $n_{\text{max}}$.

Type

Integer

Default value

8193 $(\equiv 2^{13}+1)$

Component

ALL

Behavior

Determine the size of involved arrays, such as $G(i\omega_n)$, $G_0(i\omega_n)$, $\Sigma(i\omega_n)$, and $\Delta(i\omega_n)$ etc.

Comment

mfreq = 8193 is a safe setting. We don't recommend to change it.
