We consider a pure square spin ice, that is a square ice where only nearest neighbors are coupled. A gauge-free duality between the perpendicular and collinear structure leads to a natural description in terms of topological currents and charges as the relevant degrees of freedom. That, in turn, can be expressed via a continuous field theory where the discrete spins are subsumed into entropic interactions among charges and currents. This approach produces structure factors, correlations, and…

Equilibrium field theory of magnetic monopoles in degenerate square spin ice: Correlations, entropic interactions, and charge screening regimes
We describe degenerate square spin as an ensemble of magnetic monopoles coupled via an emergent entropic field that subsumes the effect of the underlying spin vacuum. We compute their effective free
The concept of spin ice graphs and a field theory for their charges
Spin ices can now be fabricated in a variety of geometries which control their collective behavior and exotic properties. Therefore, their proper framework is graph theory. We relate spin ice notions
From confinement to deconfinement of magnetic monopoles in artificial rectangular spin ices
We study a frustrated two-dimensional array of dipoles forming an artificial rectangular spin ice with horizontal and vertical lattice parameters given by a and b respectively. We show that the ice
Extensive degeneracy, Coulomb phase and magnetic monopoles in artificial square ice
All of the characteristics of the square-ice model are observed in an artificialsquare-ice system that consists of two sublattices of nanomagnets that are vertically separated by a small distance, and provides a protocol that could be used to investigate collective magnetic phenomena, including Coulomb phases and the physics of ice-like materials.
Brownian motion and quantum dynamics of magnetic monopoles in spin ice
The results clarify the origin of the relatively high frequency response in spin ice and establish adiabatic susceptibility as a revealing characteristic of exotic spin systems.

We relate the anomaly in the noise color of spin ice to the emergent nature of its magnetic monopoles and their non-trivial random walk. Monopoles are quasi-particles, and the spin vacuum in which
Monopole Crystallization and Magnetic Moment Fractionalization on a Pyrochlore Lattice
The decomposition of the magnetic moments in spin ice into freely moving magnetic monopoles has added a new dimension to the concept of fractionalization, showing that classical geometrical
Classical spin liquid: Exact solution for the infinite-component antiferromagnetic model on the kagomé lattice
Thermodynamic quantities and correlation functions (CFs) of the classical antiferromagnet on the kagom\'e lattice are studied for the exactly solvable infinite-component spin-vector model, D \to
The Colored Noise of Spin Ice: Subdiffusion of Magnetic Monopoles in a Coevolving Vacuum
We relate the anomalous noise found experimentally in spin ice to the subdiffusion of magnetic monopoles. As emergent particles, monopoles do not move in a structureless vacuum. Rather, the
Coulomb and liquid dimer models in three dimensions.
It is conjectured that extended critical phases are realized only on bipartite lattices, even in higher dimensions, and that these models have both confined and exponentially deconfined but no critical phases.
