From: Controlled transitions between metastable states of 2D magnetocapillary crystals

The various structures adopted by a floating crystal for a number of particles between \(N=3\) to \(N=19\). Each state is named as the letter “S” followed by a number, which indicates the number of particles, and, if necessary, a letter to distinguish different states with the same number of particles. The possible transfers between states having the same number N of particles (black arrows) are obtained with the magnetic reconfiguration method. Double black arrows indicate that it is possible to switch from one state to another and vice versa. Single black arrows give the only obtained direction of transition between the two states. The possible transfers from states having N particles to ones having \(N+1\) particles (blue arrows) are obtained with the controlled growth method.
