Gapless spinons and a field-induced soliton gap in the hyper-honeycomb Cu oxalate framework compound [(C $_{2}$ H $_{5}$ ) $_{3}$ NH] $_{2}$ Cu $_{2}$ (C $_{2}$ O $_{4}$ ) $_{3}$

C. Dissanayake, A. C. Jacko, K. Kumarasinghe +14

We report a detailed study of the specific heat and magnetic susceptibility of single crystals of a spin liquid candidate: the hyper-honeycomb Cu oxalate framework compound [(C $_{2}$ …

Topological superconductivity from doping a triplet quantum spin liquid in a flat band system

Manuel Fernández López, Ben J. Powell, Jaime Merino

We explore superconductivity in strongly interacting electrons on a decorated honeycomb lattice (DHL). An easy-plane ferromagnetic interaction arises from spin-orbit coupling in th…

Flat bands and unconventional superconductivity in a simple model of metal-organic frameworks

M. F. Ohlrich, E. M. Makaresz, H. L. Nourse +1

The superconducting metal-organic framework Cu-BHT forms a kagome lattice with metals at the vertices and ligands along the bonds. This bipartite motif is common in reticular mater…

$C_{3}$ symmetry breaking metal-insulator transitions in a flat band in the half-filled Hubbard model on the decorated honeycomb lattice

H. L. Nourse, Ross H. McKenzie, B. J. Powell

We study the single-orbital Hubbard model on the half-filled decorated honeycomb lattice. In the non-interacting theory at half-filling the Fermi energy lies within a flat band whe…

$x$ -[Pd(dmit) $_{2}$ ] $_{2}$ as a quasi-1D, scalene Heisenberg model

E. P. Kenny, A. C. Jacko, B. J. Powell

From first principles, we calculate the Heisenberg interactions between neighboring dimers in several compounds within the Et $_{n}$ Me $_{4 - n} X$ [Pd(dmit) $_{2}$ ] $_{2}$ (Et = ethyl, Me = m…

Spin- $0$ Mott insulator to metal to spin- $1$ Mott insulator transition in the single-orbital Hubbard model on the decorated honeycomb lattice

H. L. Nourse, Ross H. McKenzie, B. J. Powell

We study the interplay of strong electron correlations and intra-triangle spin exchange at two-thirds filling of the single-orbital Hubbard model on the decorated honeycomb lattice…
