We review ground states and excitations of a quantum antiferromagnet on triangular and
other frustrated lattices. We pay special attention to the combined effects of magnetic field h …

Among the broad spectrum of systems predicted to exhibit topological superconductivity and
Majorana fermions, one-dimensional wires with strong spin-orbit coupling provide one of the …

The ground-state phase diagram of a spin-1 2 XXZ chain with competing ferromagnetic
nearest-neighbor (J 1< 0) and antiferromagnetic second-neighbor (J 2> 0) exchange …

Motivated by the novel phenomena observed in the layered material SrCu 2 (BO 3) 2, the
Shastry-Sutherland model (SSM) has been extensively studied as the minimal model for …

We report a thorough theoretical study of the low temperature phase diagram of Cs 2 Cu Cl
4, a spatially anisotropic spin S= 1∕ 2 triangular lattice antiferromagnet, in a magnetic field …

We investigate the phase diagram of the anisotropic spin-1/2 triangular lattice
antiferromagnet, with interchain diagonal exchange J′ much weaker than the intrachain …

We present analysis of the interacting quantum wire problem in the presence of magnetic
field and spin-orbital interaction. We show that an interesting interplay of Zeeman and spin …

We study a three-leg spin-1/2 ladder with geometrically frustrated interleg interactions. We
call this model an anisotropic triangular-strip (ATS) model. We numerically and field …

We study the transverse dynamical susceptibility of an antiferromagnetic spin-1/2 chain in
the presence of a longitudinal Zeeman field. In the low magnetization regime in the gapless …

We study the ground-state phase diagram of a spin-1 2 frustrated XXZ ladder, in which two
antiferromagnetic chains are coupled by competing rung and diagonal interactions, J⊥ and …
