متن کاملObservation of topological phase transitions in photonic quasicrystals.
Topological insulators and topological superconductors are distinguished by their bulk phase transitions and gapless states at a sharp boundary with the vacuum. Quasicrystals have recently been found to be topologically nontrivial. In quasicrystals, the bulk phase transitions occur in the same manner as standard topological materials, but their boundary phenomena are more subtle. In this Letter...
متن کاملPhase Transitions in Systems of Interacting Species
We discuss an autocatalytic reaction system: the cyclic competition model A1 + A2 → 2A2, A2 + A3 → 2A3, A3 + A4 → 2A4, A4 + A1 → 2A1), as well as its neutral counterpart. Migrations are introduced into the model. When stochastic phenomena are taken into account, a phase transition between a “fixation” and a “neutral” regime is observed. In the “fixation” regime, species A1 and A3 form an allian...
متن کاملTopological Phase Transitions in the Repulsively Interacting Haldane-Hubbard Model.
Using dynamical mean-field theory and exact diagonalization we study the phase diagram of the repulsive Haldane-Hubbard model, varying the interaction strength and the sublattice potential difference. In addition to the quantum Hall phase with Chern number C=2 and the band insulator with C=0 present already in the noninteracting model, the system also exhibits a C=0 Mott insulating phase, and a...
متن کاملPhase transitions in isolated strongly interacting systems
Thermodynamical properties of nuclear matter at sub-saturation densities were investigated using a simple van der Waals-like equation of state with an additional term representing the symmetry energy. First-order isospin-asymmetric liquid-gas phase transition appears restricted to isolated isospin-asymmetric systems while the symmetric systems will undergo fragmentation decay resembling the sec...
