Spinon confinement and a sharp longitudinal mode in Yb(2)Pt(2)Pb in magnetic fields
The fundamental excitations in an antiferromagnetic chain of spins-1/2 are spinons, de-confined fractional quasiparticles that when combined in pairs, form a triplet excitation continuum. In an Ising-like spin chain the continuum is gapped and the ground state is Néel ordered. Here, we report high r...
