Field-induced spin level crossings within a quasi-XY antiferromagnetic state in Ba $_{2}$ FeSi $_{2}$ O $_{7}$

Minseong Lee, Rico Schoenemann, Hao Zhang +11

We present a high-field study of the strongly anisotropic easy-plane square lattice $S$ = 2 quantum magnet Ba $_{2}$ FeSi $_{2}$ O $_{7}$ . This compound is a rare high-spin antiferromag…

Understanding temperature-dependent SU( $3$ ) spin dynamics in the $S = 1$ antiferromagnet Ba $_{2}$ FeSi $_{2}$ O $_{7}$

Seung-Hwan Do, Hao Zhang, David A. Dahlbom +9

Quantum magnets admit more than one classical limit and $N$ -level systems with strong single-ion anisotropy are expected to be described by a classical approximation based on SU($N…

Incarnation of Majorana Fermions in Kitaev Quantum Spin Lattice

Seung-Hwan Do, Sang-Youn Park, Junki Yoshitake +10

Kitaev quantum spin liquid is a topological magnetic quantum state characterized by Majorana fermions of fractionalized spin excitations, which are identical to their own antiparti…
