Landau Phase Transition Principles Balance Exploration and Exploitation in Swarm Optimization
Researchers have derived a swarm optimization algorithm from the Landau theory of phase transitions, using spontaneous symmetry breaking to govern ...
Flexible ligands give symmetric nanoparticles spontaneous valency
Flexible polymer ligands let isotropic nanoparticles acquire effective valency during assembly, forming lower-coordination, lower-symmetry superlattices than hard-sphere packing predicts.
Acoustic Dirac Equation Turns Sound Waves Into a Model of Topological Insulators
Researchers at the University of Arizona have shown that the Dirac factorization of a simple mass-and-spring chain exposes acoustic pseudospins, ...
