Quantum spin-ice and dimer models with Rydberg atoms.
Of particular interest at the moment are "quantum spin-ice" materials, where large quantum fluctuations may permit tunnelling between a macroscopic number of different classical ground states. Here we use zero-temperature quantum Monte Carlo simulations to show how such tunnelling can lift the degeneracy of a spin or charge ice, stabilizing a.

For the Coulomb phase of spin ice, we find quantum effects to be most visible in the gauge-charged monopole excitations. In the presence of weak dilution with nonmagnetic ions we find a particularly crisp phenomenon, namely, the emergence of hydrogenic excited states in which a magnetic monopole is bound to a vacancy at various distances..

Abstract: Quantum spin liquids are low temperature phases of magnetic materials in which quantum fluctuations prevent the establishment of long-range magnetic order. These phases support fractionalized spin excitations (spinons) coupled to emergent photons. In this talk, I will review the basic picture of how quantum electrodynamics emerges in 3D spin ice and then turn to several results. We implemented a two-dimensional (2D) spin ice of superconducting qubits—macroscopic quantum objects ( 14 )—in a quantum annealing (QA) system and drove it between low-energy quasi-classical states by means of primarily quantum rather than thermal fluctuations, thus opening the door to future studies of quantum phases in these systems ( 15, 16 ).

In the presence of quantum fluctuations, one can obtain, in principle, a quantum spin liquid descended from the classical spin ice state characterised by emergent photon-like excitations. Whereas in classical spin ices the excitations are akin to electrostatic charges, in the quantum spin liquid these charges interact through a dynamic and.

The search for experimental realizations of quantum spin liquid and quantum spin ice (QSI) states is of great current interest [1,2] due to the potential for exotic physics within these systems. Geometrically frustrated magnetic materials are central to the discovery of such exotic states [3]. Besides. The Coulombic quantum spin liquid in quantum spin ice is an exotic quantum phase of matter that emerges on the pyrochlore lattice and is currently actively searched for. Motivated by recent experiments on the Yb-based breathing pyrochlore material Ba[subscript 3] Yb[subscript 2] Zn[subscript 5] O[subscript 11], we theoretically study the phase. 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.

[1311.1817] Quantum Spin Ice: A Search for Gapless Quantum.
A spin ice is a three-dimensional network of corner-sharing tetrahedra with spins at the vertices. At low energies the spins obey "ice rules," i.e., they point towards or away from the center of the tetrahedron in a two-in and two-out configuration, similar to positions of protons around an oxygen atom in ordinary ice. In view of the small size of its constrained Hilbert space, this marks out quantum spin ice as an ideal platform for studying exotic quantum field theories and a target for quantum simulation. The large α Q S I implies that experiments probing candidate condensed-matter realizations of quantum spin ice should expect to observe phenomena. S. Chillal Y. Iqbal Department of Physics, Indian Institute of Technology Madras, Chennai 600036, India H. O. Jeschke Research Institute for Interdisciplinary Science, Okayama Uni.

At the most general level, Quantum Spin Ice refers to a pyrochlore system in which ice-rule obeying configurations are endowed with dynamics from quantum fluctuations. To generate such a state experimentally, material candidates must support anisotropic exchange interactions between localized spins on the pyrochlore lattice. Dep. Phys. Astron., Univ.
