A polymer escaping from the metastable potential well.
An order parameter field of a rotated grain within a crystal shrinking and turning as it approaches equilibrium state. White spots correspond to liquid-like regions.
A growing bubble of steam (blue) growing in water (orange) in contact with a hot plate (black surface). The bubble dynamics is faithfully modeled by numerically solving the full set of full, compressible thermohydrodynamic Navier-Stokes equations developed in collaboration with the group of G. Amberg at The Royal Institute of Technology in Stockholm, Sweden [T. Laurila et al., Phys. Rev. E vol. 85, 026320 (2012)]. Inset shows the adaptive numerical grid at the two-phase interface.
Phase-field crystal model of a strained Cu overlayer on Ru(0001) surface. The blue and red colors indicate the two different sublattices for Cu adsorbates, which are separates by yellow domain walls (incommensurate regions).
