alma::Nabla_T_distribution Class Reference

Objects of this class allow us to sample from a discrete distribution over a q-point grid with a PMF proportional to one component of the group velocity and to each mode's contribution to the specific heat. More...

Detailed Description

Objects of this class allow us to sample from a discrete distribution over a q-point grid with a PMF proportional to one component of the group velocity and to each mode's contribution to the specific heat.

Make sure to select the right sign after sampling from this distribution.
