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 …

A theoretical overview of the phenomenon of spontaneous magnon decays in quantum
antiferromagnets is presented. The intrinsic zero-temperature damping of magnons in …

We elucidate the role of magnon interaction and spontaneous decays in the spin dynamics
of the triangular-lattice Heisenberg antiferromagnet by calculating its dynamical structure …

Spin-frustrated systems are well known for exhibiting fascinating and exotic magnetic
properties and are often intertwined with other intriguing phenomena. Magnetization and …

We consider frustrated Heisenberg antiferromagnets, whose clean-limit ground state is
characterized by noncollinear long-range order with nonzero vector chirality, and study the …

In geometrically frustrated materials with low-dimensional and small spin moment, the
quantum fluctuation can interfere with the complicated interplay of the spin, electron, lattice …

Hypothetical metals having optical absorption losses as low as those of the transparent
insulators, if found, could revolutionize optoelectronics. We perform a high-throughput …

The effect of substituting iron and zinc for cobalt in CaBaCo4O7 was investigated using
neutron diffraction and X-ray absorption spectroscopy techniques. The orthorhombic …

We investigate the experimental signatures of Raman spectroscopy of bimagnon and
trimagnon excitations in the distorted triangular lattice antiferromagnets α-L Cr 2 O 4 (L= Sr …

Single crystals of the three-dimensional frustrated magnet and spin liquid candidate PbCuTe
2 O 6 were grown using both the traveling solvent floating zone and the top-seeded solution …
