摘 要：

We present a general-purpose Collective Coordinate Model for scalar field dynamics in 1+1 dimensions that we dubb "mechanization". The idea is to "chop up" a continuous field into N straight segments. The positions of joints and slopes of the segments become the collective coordinates in a family of effective mechanical theories. We show that even such a simplistic "triangulation" of configuration space does capture all essential phenomena of field dynamics in the case of the Φ⁴ model. We emphasize the benefits and drawbacks of our approach and point out future directions.
