Accelerating dynamical mean-field theory convergence by preconditioning with computationally cheaper quantum embedding methods
E. M. Makaresz, O. Gingras, Tsung-Han Lee +3
Dynamical mean-field theory (DMFT) is a cornerstone technique for studying strongly correlated electronic systems. However, each DMFT step is computationally demanding, and many it…
Fingerprints of collective magnetic excitations in inelastic electron tunneling spectroscopy
Finnian Rist, Henry L. Nourse, Ben J. Powell
Spin-flip inelastic electron tunneling spectroscopy allows magnetic materials to be probed at the single-atom level via scanning tunneling microscopy. Previously, the local spectra…
Competing quantum effects in spin crossover chains: spin-orbit coupling, magnetic exchange, and elastic interactions
Finnian Rist, Henry L. Nourse, Ben J. Powell
We derive and study a model of square planar, d8 spin crossover materials that treats elastic, magnetic and spin-orbit interactions on an equal footing. For 1D chains density matri…
Raman scattering signatures of spinons and triplons in frustrated antiferromagnets
O. R. Bellwood, H. L. Nourse, B. J. Powell
Magnetically frustrated spin systems compose a significant proportion of topological quantum spin liquid candidates. Evidence for spin liquids in these materials comes largely from…
Local gate control of Mott metal-insulator transition in a 2D metal-organic framework
Benjamin Lowe, Bernard Field, Jack Hellerstedt +5
Electron-electron interactions in materials lead to exotic many-body quantum phenomena including Mott metal-insulator transitions (MITs), magnetism, quantum spin liquids, and super…
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…
Spin- Mott insulator to metal to spin- 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…
Multiple insulating phases due to the interplay of strong correlations and lattice geometry in a single-orbital Hubbard model
H. L. Nourse, Ross H. McKenzie, B. J. Powell
We report ten ground states arising from strong correlations in the single-orbital Hubbard model on the decorated honeycomb lattice; including Dirac metals, flat-band ferromagnets,…
Haldane insulator protected by reflection symmetry in the doped Hubbard model on the three-legged ladder
H. L. Nourse, I. P. McCulloch, C. Janani +1
We demonstrate the existence of an insulating phase in the three-legged Hubbard ladder at two-thirds filling. In this phase chargons are bound because the physics within a unit cel…
