Molecules show novel properties by assembling themselves. Such properties can often be controlled. For example, variation of the composition, application of pressure, and/or irradiation of molecular assemblies induce changes in their crystal structures, colors, and/or magnetic properties. They may induce even superconductivity. Away from equilibrium, spatially local seeds of such changes may appear, compete with each other, proliferate and finally dominate the global phase. Microscopically, the quantum-mechanical states of many-electron systems are accordingly changed. We theoretically investigate their mechanisms and accompanied phase dynamics.
