Fluctuation-induced spin nematic order in magnetic charge-ice
A. Hemmatzade, K. Essafi, M. Taillefumier +3
Disorder in materials may be used to tune their functionalities, but much more strikingly, its presence can entail entirely new behavior. This happens in charge-ice where structura…
Universal behaviors in the wrinkling transition of disordered membranes
O. Coquand, K. Essafi, J. -P. Kownacki +1
The wrinkling transition experimentally identified by Mutz et al. [Phys. Rev. Lett. 67, 923 (1991)] and then thoroughly studied by Chaieb et al. [Phys. Rev. Lett. 96, 078101 (2006)…
Effect of perturbations on the kagome antiferromagnet at all temperatures
Bernard Bernu, Laurent Pierre, Karim Essafi +1
The ground state of the kagome Heisenberg antiferromagnet is now recognized as a spin liquid, but its precise nature remains unsettled, even if more and more clues point to…
A glassy phase in quenched disordered graphene and crystalline membranes
O. Coquand, K. Essafi, J. -P. Kownacki +1
We investigate the flat phase of -dimensional crystalline membranes embedded in a -dimensional space and submitted to both metric and curvature quenched disorders using a non…
Generic nearest-neighbour kagome model: XYZ & Dzyaloshinskii-Moriya, and comparison to pyrochlore
Karim Essafi, Owen Benton, L. D. C. Jaubert
The kagome lattice is a paragon of geometrical frustration, long-studied for its association with novel ground-states including spin liquids (SLs). Many recently synthesized kagome…
A Kagome Map of Spin Liquids: from XXZ to Dzyaloshinskii-Moriya Ferromagnet
K. Essafi, Owen Benton, Ludovic D. C. Jaubert
The kagome lattice sits at the crossroad of present research efforts in quantum spin liquids, chiral phases, emergent skyrmion excitations and anomalous Hall effects to name but a…
