Query: Domain Walls and Double Bubbles   We study configurations of intersecting domain walls in a Wess-Zumino model
with three vacua. We introduce a volume-preserving flow and show that its
static solutions are configurations of intersecting domain walls that form
double bubbles, that is, minimal area surfaces which enclose and separate two
prescribed volumes. To illustrate this field theory approach to double bubbles,
we use domain walls to reconstruct the phase diagram for double bubbles in the
flat square two-torus and also construct all known examples of double bubbles
in the flat cubic three-torus.
