Quantum fluctuations drive nonmonotonic correlations in a qubit lattice

A Lopez-Bezanilla, AD King, C Nisoli… - Nature …, 2024 - nature.com
Fluctuations may induce the degradation of order by overcoming ordering interactions,
consequently leading to an increase of entropy. This is particularly evident in magnetic …

Order and disorder, crossovers, and phase transitions in dipolar artificial spin ice on the Cairo lattice

Y Shevchenko, V Strongin, V Kapitan, K Soldatov… - Physical Review E, 2022 - APS
We study the thermodynamic properties of the magnetic dipolar spin ice on a 2D pentagonal
Cairo lattice by using the numerical Metropolis and the complete enumeration methods. We …

Magnetic monopole free motion in two-dimensional artificial spin ice

DG Duarte, LB de Oliveira, FS Nascimento… - Applied Physics …, 2024 - pubs.aip.org
Magnetic monopole motion (without its partner in a pair) as a function of external magnetic
fields is presented as a fingerprint of freedom of these emergent quasi-particles in a two …

Approaching the Topological Low-Energy Physics of the Model in a Two-Dimensional Magnetic Lattice

V Schánilec, O Brunn, M Horáček, S Krátký… - Physical Review Letters, 2022 - APS
We demonstrate that the physics of the F model can be approached very closely in a two-
dimensional artificial magnetic system. Faraday lines spanning across the lattice and …

Polymerization in magnetic metamaterials
