Spinon Confinement and Longitudinal Interchain modes in Yb2Pt2Pb
The f-electron metal Yb2Pt2Pb is best thought of as a one dimensional (1D) quantum spin chain system, despite the fact that the magnetic moments are large and anisotropic with... -
Magnetic critical scattering in UGe2 under pressure
The proposal is to measure the low-energy spin dynamics of the ferromagnetic superconductor UGe2 at the pressure which maximizes superconducting transition temperature and at... -
Fractional spinon excitations in triangular-lattice quantum-spin-liquid candi...
A quantum spin liquid (QSL) is an exotic state of matter, which shows no magnetic order down to zero temperature but the spins are highly entangled. Its elementary excitations... -
Fractionalized excitations in the zigzag pseudospin-1/2 quantum chain compoun...
One-dimensional (1D) S = 1/2 spin chains are a subject of long-standing interest, because conventional long-range ordering can be prevented and novel Luttinger-liquid phase may... -
Fractionalized spin excitation and crystal electric field study in the rare-e...
A new rare-earth triangular quantum spin liquid (QSL) candidate, YbMgGaO4, has an odd number of electrons per unit cell and spin-orbit entangled effective spin-1/2 (Yb3+).... -
Spin dynamics in the extended Kagome system YBaCo4O(7+x)
A recently discovered new class of geometrically frustrated magnets is the family of cobalt oxides RBaCo4O7 (R=rare earth or Y). The structure is built up CoO4 tetrahedra which...
