Detailed Description

Exc class. It is a helper class to Ropewalk, used to describe a pair of excitations needed for shoving. It is kept away from users, as there are a lot of raw pointers floating around.

Member Function Documentation

void setParticlePtrs ( Particle p1,
Particle p2 
)
inline

Set pointers to the two excitation particles.

Set a pointer to the excitation in the dipole.

void shove ( double  dpx,
double  dpy 
)
inline

Give the excitation a kick in the x and y direction,.

The old momenta.

The new momenta, after the shove.

The differences between the two.

Now check if we can add these two excitations to the dipoles.
