Multiphase Magnetism in Yb2Ti2O7
A. Scheie, J. Kindervater, S. Zhang +7
We document the coexistence of ferro- and anti-ferromagnetism in pyrochlore using three neutron scattering techniques on stoichiometric crystals: elastic neutron…

SU(3) Topology of Magnon-Phonon Hybridization in 2D Antiferromagnets
Shu Zhang, Gyungchoon Go, Kyung-Jin Lee +1
Magnon-phonon hybrid excitations are studied theoretically in a two-dimensional antiferromagnet with an easy axis normal to the plane. We show that two magnon bands and one phonon…

Quantum statistics of vortices from a dual theory of the XY ferromagnet
Sayak Dasgupta, Shu Zhang, Ibrahima Bah +1
We extend the well-known mapping between the easy-plane ferromagnet and electrostatics in spatial dimensions to dynamical and quantum phenomena in a spacetime. Ferrom…
