The hexagonal versus the square lattice [PDF]
Mathematics of Computation, 2002 We establish Schmutz Schaller's conjecture that the hexagonal lattice is `better' than the square lattice. Schmutz Schaller (Bulletin of the AMS 35 (1998), p.

Skyrmions in square-lattice antiferromagnets [PDF]
Physical Review B, 2016 The ground states of square-lattice two-dimensional antiferromagnets with anisotropy in an external magnetic field are determined using Monte Carlo simulations and compared to theoretical analysis.

Emotional agents at the square lattice [PDF]
Acta Physica Polonica A, 2010 We introduce and investigate by numerical simulations a number of models of emotional agents at the square lattice. Our models describe the most general features of emotions such as the spontaneous emotional arousal, emotional relaxation, and transfers ...

Coincidence isometries of a shifted square lattice [PDF]
Journal of Physics: Conference Series, 2010 We consider the coincidence problem for the square lattice that is translated by an arbitrary vector. General results are obtained about the set of coincidence isometries and the coincidence site lattices of a shifted square lattice by identifying the ...

Interacting classical dimers on the square lattice [PDF]
Physical Review Letters, 2005 We study a model of close-packed dimers on the square lattice with a nearest neighbor interaction between parallel dimers. This model corresponds to the classical limit of quantum dimer models [D.S. Rokhsar and S.A. Kivelson, Phys. Rev.

The Heisenberg antiferromagnet on the square-kagomé lattice [PDF]
Condensed Matter Physics, 2009 We discuss the ground state, the low-lying excitations as well as high-field thermodynamics of the Heisenberg antiferromagnet on the two-dimensional square-kagomé lattice.

Nanometric square skyrmion lattice in a centrosymmetric tetragonal magnet [PDF]
Nature Nanotechnology, 2020 Magnetic skyrmions are topologically stable spin swirls with a particle-like character and are potentially suitable for the design of high-density information bits.

Finite crystallization in the square lattice [PDF]
Nonlinearity, 2014 This paper addresses two-dimensional crystallization in the square lattice. A suitable configurational potential featuring both two- and three-body short-ranged particle interactions is considered. We prove that every ground state is a connected subset of the square lattice. Moreover, we discuss the global geometry of ground states and their optimality
