We have performed nuclear magnetic resonance (NMR) experiments on the quasi-one-
dimensional frustrated spin-1/2 system LiCuVO 4 in magnetic fields H applied along the c …

We develop a microscopic theory of finite-temperature spin-nematic orderings in three-
dimensional spatially anisotropic magnets consisting of weakly coupled frustrated spin-1 2 …

We study the excitation spectrum and dynamical response functions for several quasi-one-
dimensional spin systems in magnetic fields without dipolar spin order transverse to the …

We present a detailed study in the paramagnetic regime of the frustrated s= 1/2 spin-
compound linarite PbCuSO 4 (OH) 2 with competing ferromagnetic nearest-neighbor and …

Modern theories of quantum magnetism predict exotic multipolar states in weakly interacting
strongly frustrated spin-1/2 Heisenberg chains with ferromagnetic nearest neighbor (NN) …

We present a direct NMR method to determine whether the interactions in a Tomonaga-
Luttinger liquid (TLL) state of a spin-1/2 Heisenberg antiferromagnetic ladder are attractive …

We develop a theory of spin excitations in a field-induced spin-nematic state, and use it to
show how a spin-nematic order can be indentified using inelastic neutron scattering. We …

We report results of NMR experiments on a single crystal of the quasi one-dimensional
frustrated magnet LiCuVO4. The NMR spectra of 7Li and 51V nuclei indicate a helical spin …

We present a mathematical framework for the multi-boson approach that has been used
several times for treating spin systems. We demonstrate that the multi-boson approach …

The J 1-J 2 spin-chain model with nearest-neighbor J 1 and next-nearest-neighbor
antiferromagnetic J 2 interaction is one of the most popular frustrated magnetic models. This …
