Quantum Spin-Ice and Dimer Models with Rydberg Atoms

Glaetzle, A. W.; Dalmonte, M.; NATH, REJISH; Rousochatzakis, I; Moessner, R.; Zoller, P. (American Physical Society, 2014-11)

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 ...
Designing Frustrated Quantum Magnets with Laser-Dressed Rydberg Atoms

Glaetzle, Alexander W.; Dalmonte, Marcello; NATH, REJISH; Gross, Christian; Bloch, Immanuel; Zoller, P. (American Physical Society, 2015-04)

We show how a broad class of lattice spin- 1 / 2 models with angular- and distance-dependent couplings can be realized with cold alkali atoms stored in optical or magnetic trap arrays. The effective spin- 1 / 2 is represented ...
Hexagonal plaquette spin–spin interactions and quantum magnetism in a two-dimensional ion crystal

NATH, REJISH; Dalmonte, M.; Glaetzle, A. W.; Zoller, P.; Schmidt-Kaler, F.; Gerritsma, R. (IOP Publishing, 2015-06)

We propose a trapped ion scheme en route to realize spin Hamiltonians on a Kagome lattice which, at low energies, are described by emergent ${{\mathbb{Z}}}_{2}$ gauge fields, and support a topological quantum spin liquid ...
