Emergent transverse-field Ising model in spin-orbit Mott insulators

Jiří Chaloupka

Mott-insulating transition metal oxides containing ions with strong spin-orbit coupling were recently demonstrated to display unusual magnetism due to a dynamical mixing…

Highly frustrated magnetism in relativistic Mott insulators: Bosonic analog of Kitaev honeycomb model

Jiří Chaloupka, Giniyat Khaliullin

We study the orbitally frustrated singlet-triplet models that emerge in the context of spin-orbit coupled Mott insulators with electronic configuration. In these compoun…

Higgs mode and its decay in a two dimensional antiferromagnet

A. Jain, M. Krautloher, J. Porras +9

Condensed-matter analogs of the Higgs boson in particle physics allow insights into its behavior in different symmetries and dimensionalities. Evidence for the Higgs mode has been…

Direct Evidence for Dominant Bond-directional Interactions in a Honeycomb Lattice Iridate Na2IrO3

Sae Hwan Chun, Jong-Woo Kim, Jungho Kim +15

Heisenberg interactions are ubiquitous in magnetic materials and have been prevailing in modeling and designing quantum magnets. Bond-directional interactions offer a novel alterna…

Spin-Orbital Liquid on a Triangular Lattice

Andrzej M. Oleś, Jiří Chaloupka

Using Lanczos exact diagonalization of finite clusters we demonstrate that the spin-orbital model for triply degenerate orbitals on a triangular lattice provides an…

Intense paramagnon excitations in a large family of high-temperature superconductors

M. Le Tacon, G. Ghiringhelli, J. Chaloupka +17

In the search for the mechanism of high-temperature superconductivity, intense research has been focused on the evolution of the spin excitation spectrum upon doping from the antif…
