A Kitaev material on the triangular lattice: The case of NaRuO

Aleksandar Razpopov, David A. S. Kaib, Steffen Backes +5

Motivated by recent reports of a quantum disordered ground state in the triangular lattice compound NaRuO, we derive a magnetic model for this system by means…

Projective symmetry group classification of Abrikosov fermion mean-field ansätze on the square-octagon lattice

Atanu Maity, Francesco Ferrari, Ronny Thomale +2

We perform a projective symmetry group (PSG) classification of symmetric quantum spin liquids with different gauge groups on the square-octagon lattice. Employing the Abrikosov fer…

Detecting topological phases in the square-octagon lattice with statistical methods

Paul Wunderlich, Francesco Ferrari, Roser Valentí

Electronic systems living on Archimedean lattices such as kagome and square-octagon networks are presently being intensively discussed for the possible realization of topological i…

Static and dynamical signatures of Dzyaloshinskii-Moriya interactions in the Heisenberg model on the kagome lattice

Francesco Ferrari, Sen Niu, Juraj Hasik +3

Motivated by recent experiments on CsCuSnF and YCu(OH)Cl, we consider the Heisenberg model on the kagome lattice with nearest-neighbor su…

Pinch-points to half-moons and up in the stars: the kagome skymap

Dominik Kiese, Francesco Ferrari, Nikita Astrakhantsev +9

Pinch point singularities, associated with flat band magnetic excitations, are tell-tale signatures of Coulomb spin liquids. While their properties in the presence of quantum fluct…

Charge-density waves in kagome-lattice extended Hubbard models at the van Hove filling

Francesco Ferrari, Federico Becca, Roser Valentí

The Hubbard model on the kagome lattice is presently often considered as a minimal model to describe the rich low-temperature behavior of AVSb compounds (with A=K, Rb,…
