Continuous Spatial Public Goods Game Based on Particle Swarm Optimization with Memory Stability

Mathematics, 2022
Public goods games have been extensively studied to determine the mechanism behind cooperation in social dilemmas. Previous public goods games based on particle swarm algorithms enabled individuals to integrate their past best strategies with the current

Conductivity in the Square Lattice Hubbard Model at High Temperatures: Importance of Vertex Corrections. [PDF]

Physical Review Letters, 2018
Recent experiments on cold atoms in optical lattices allow for a quantitative comparison of the measurements to the conductivity calculations in the square lattice Hubbard model. However, the available calculations do not give consistent results, and the

Rashba Effect on Buckled Square Lattice Ge and Sn chalcogenides (MX, M=Ge,Sn, X=O,S,Se,Te) using DFT method

Indonesian Journal of Chemistry, 2020
The Rashba splitting are found in the buckled square lattice. Here, by applying fully relativistic density-functional theory (DFT) calculation, we confirm the existence of the Rashba splitting in the conduction band minimum of various two-dimensional MX ...

Quantum dynamics of the square-lattice Heisenberg model [PDF]

Physical review B, 2018
Despite nearly a century of study of the $S=1/2$ Heisenberg model on the square lattice, there is still disagreement on the nature of its high-energy excitations.

Estimates of threshold and strength of percolation clusters on square lattices with (1,)-neighborhood [PDF]

Компьютерные исследования и моделирование, 2014
In this paper we consider statistical estimates of threshold and strength of percolation clusters on square lattices. The percolation threshold pc and the strength of percolation clusters P for a square lattice with (1,)-neighborhood depends not only on ...

Thermodynamics of a frustrated quantum magnet on a square lattice [PDF]

Physical review B, 2018
We report the magnetic and calorimetric measurements in single crystal samples of the square lattice $J_{1}-J_{2}$ quantum antiferromagnet BaCdVO(PO$_4$)$_2$.

Effective One-Dimensional Coupling in the Highly Frustrated Square-Lattice Itinerant Magnet CaCo_{2-y}As_{2}. [PDF]

Physical Review Letters, 2017
Inelastic neutron scattering measurements on the itinerant antiferromagnet CaCo_{2-y}As_{2} at a temperature of 8 K reveal two orthogonal planes of scattering perpendicular to the Co square lattice in reciprocal space, demonstrating the presence of ...

Escher squares and lattice links [PDF]

Topology and its Applications, 2019
We give a shorter and simpler proof of the result of [2], which gives a necessary and sufficient condition for when a lattice diagram is the projection of a lattice link.
