Phase Transition in Ant Colony Optimization

open access: yesPhysics
Ant colony optimization (ACO) is a stochastic optimization algorithm inspired by the foraging behavior of ants. We investigate a simplified computational model of ACO, wherein ants sequentially engage in binary decision-making tasks, leaving pheromone ...

Baryon asymmetry from left-right phase transition

open access: yesPhysics Letters B, 2020
We extend the standard model fermions by a mirror copy to realize a left-right symmetry. During a strongly first order phase transition of the spontaneous left-right symmetry breaking, the CP-violating reflections of the mirror fermions off the mirror ...

λ Phase Transition in Horava Gravity

open access: yesAdvances in High Energy Physics, 2018
We present another example of superfluid black hole containing λ phase transition in Horava gravity. After studying the extended thermodynamics of general dimensional Horava-Lifshitz AdS black holes, it is found that only the one with spherical horizon ...

Hamiltonian limited valence model for liquid polyamorphism

open access: yesCondensed Matter Physics
Liquid-liquid phase transitions have been found experimentally or by computer simulations in many compounds such as water, hydrogen, sulfur, phosphorus, carbon, silica, and silicon.

Phase transitions of ε-HNIW in compound systems

open access: yesAIP Advances, 2016
The heat-induced phase transitions of ε-HNIW, both neat and coated with various additives used in plastic bonded explosives, were investigated using powder X-ray diffraction and differential scanning calorimetry.

Effects of phase-transition heat on fracture temperature in self-propping phase-transition fracturing technology

open access: yesPetroleum Exploration and Development
The thermal flux curve of phase-transition fluid (PF) was tested using differential scanning calorimetry, based on which a reaction kinetics model was established to reflect the relationship between phase transition conversion rate, temperature and time.
