We consider quantum spin ice in a temperature regime in which its response is dominated by the coherent motion of a dilute gas of monopoles through an incoherent spin background, taken to be quasistatic on the relevant timescales. The latter introduces well-known blocked directions that we find sufficient to reduce the coherent propagation of. Introduction. This book deals with a new class of magnetic materials, spin ice. Spin ice has become the canonical example of modern frustrated magnetism where competing interactions between spins set the rules for an emergent magnetostatic gauge field theory. Excitations take the form of magnetic monopoles or can condense via a Higgs mechanism.

APS -APS March Meeting 2022 - Event - Deconfinement-confinement.

Quantum spin-ice represents a paradigmatic example of how the physics of frustrated magnets is related to gauge theories. In the present work, we address the problem of approximately realizing quantum spin ice in two dimensions with cold atoms in optical lattices. The relevant interactions are obtained by weakly laser-admixing Rydberg states to. Dep. Phys. Astron., Univ. Waterloo, Waterloo, Ont. N2L 3G1, Can. Search for more papers by this author.

Intoduction to Artificial Spin System.

This vindicates Yb2Ti2O7 as a model quantum spin ice. We find that in the perturbative weak quantum regime, such a system has a ferrimagnetic ordered ground state, with two peaks in C(T): a Schottky anomaly signaling the paramagnetic to spin ice crossover, followed at a lower temperature by a sharp peak accompanying a first-order phase. We develop a theory of the dynamical response of a minimal model of quantum spin ice (QSI) by means of inelastic light scattering. In particular, we are interested in the Raman response of the fractionalized U(1) spin liquid realized in the XXZ QSI.We show that the low-energy Raman intensity is dominated by spinon and gauge fluctuations. Spinoff highlights NASA technologies that benefit life on Earth in the form of commercial products.

May 11, 2022 · Because electrons possess a fundamental quantum mechanical property called spin — a measure of the electron’s intrinsic angular momentum — and an electron’s spin can be either +½ or -½. Quantum spin ice is a special class of quantum spin liquid, known as U (1) spin liquid in 3D, whose low-energy fluctuations are described by a U (1) gauge theory (hence the name U (1)). More general spin liquids are not limited to 3D (in fact 2D spin liquids are largely discussed) and the gauge group is not limited to U (1).

In Physical Review B, Owen Benton and his colleagues at the University of Bristol, UK, ask what "photons," which emerge in the quantum version of a spin ice, would look like in an experiment. The most common spin ices have a structure consisting of corner sharing tetrahedra, with a spin at each corner.

A spin ice is a magnetic substance that does not have a single minimal-energy state.It has magnetic moments (i.e. "spin") as elementary degrees of freedom which are subject to frustrated interactions.By their nature, these interactions prevent the moments from exhibiting a periodic pattern in their orientation down to a temperature much below the energy scale set by the said interactions.

Here we report a realization of spin ice in a lattice of superconducting qubits. Unlike conventional artificial spin ice, our system is disordered by both quantum and thermal fluctuations. The ground state is classically described by the ice rule, and we achieve control over a fragile degeneracy point leading to a Coulomb phase.
