Majorana-Hubbard model on the square lattice [PDF]

open access: yes, 2017
We study a tight-binding model of interacting Majorana (Hermitian) modes on a square lattice. The model may have an experimental realization in a superconducting-film--topological-insulator heterostructure in a magnetic field.

Application of the lattice Green's function for calculating the resistance of an infinite networks of resistors [PDF]

open access: yes, 2000
We calculate the resistance between two arbitrary grid points of several infinite lattice structures of resistors by using lattice Green's functions.

Magnetic structure of the S =1/2 quasi-two-dimensional square-lattice Heisenberg antiferromagnet Sr 2 CuTeO 6 [PDF]

open access: yes, 2016
The magnetic structure of the double perovskite compound Sr$_2$CuTeO$_6$ was determined from neutron powder diffraction data. This material is magnetically described as an $S\,{=}\,1/2$ quasi-two-dimensional square-lattice Heisenberg model with ...

Quantum algorithms for classical lattice models [PDF]

open access: yes, 2011
We give efficient quantum algorithms to estimate the partition function of (i) the six vertex model on a two-dimensional (2D) square lattice, (ii) the Ising model with magnetic fields on a planar graph, (iii) the Potts model on a quasi 2D square lattice,

Simulating excitation spectra with projected entangled-pair states [PDF]

open access: yes, 2018
We develop and benchmark a technique for simulating excitation spectra of generic two-dimensional quantum lattice systems using the framework of projected entangled-pair states (PEPS).

The topologically-disordered square lattice [PDF]

open access: yesJournal de Physique, 1990
The topological defect method, consisting of modifying the topology of a crystalline supercell by breaking and reforming bonds between cations, is applied to a two-dimensional square lattice to simulate four-coordinated AB2 systems after introduction of anions.

Equivariant neural networks for spin dynamics simulations of itinerant magnets

open access: yesMachine Learning: Science and Technology, 2023
I present a novel equivariant neural network architecture for the large-scale spin dynamics simulation of the Kondo lattice model. This neural network mainly consists of tensor-product-based convolution layers and ensures two equivariances: translations ...

Tuning Pore Size in Square-Lattice Coordination Networks for Size-Selective Sieving of CO2.

open access: yesAngewandte Chemie, 2016
Porous materials capable of selectively capturing CO2 from flue-gases or natural gas are of interest in terms of rising atmospheric CO2 levels and methane purification. Size-exclusive sieving of CO2 over CH4 and N2 has rarely been achieved.

On the growth constant for square-lattice self-avoiding walks [PDF]

open access: yes, 2016
The growth constant for two-dimensional self-avoiding walks on the honeycomb lattice was conjectured by Nienhuis in 1982, and since that time the corresponding results for the square and triangular lattices have been sought.
