Electrical Probing of Sub-Néel Spin Dynamics in Two-Dimensional Antiferromagnets Using Graphene Heterostructures
Adrián García-Martín, Sara Gullace, Nicolás Montenegro-Pohlhammer +4
Low-dimensional antiferromagnetic van der Waals materials have emerged as a versatile platform for exploring exotic spin dynamics and magnetic phases, yet electrically accessing th…
Tuning the confinement potential between spinons in the Ising chain CoNb2O6 using longitudinal fields and quantitative determination of the microscopic Hamiltonian
Leonie Woodland, David Macdougal, Ivelisse M. Cabrera +4
The Ising chain realizes the fundamental paradigm of spin fractionalization, where locally flipping a spin creates two domain walls (spinons) that can separate apart at no energy c…
Quasiparticle Breakdown and Spin Hamiltonian of the Frustrated Quantum Pyrochlore YbTiO in Magnetic Field
J. D. Thompson, P. A. McClarty, D. Prabhakaran +3
The frustrated pyrochlore magnet YbTiO has the remarkable property that it orders magnetically, but has no propagating magnons over wide regions of the Brillouin zone.…
"Quasi-particle breakdown" in the quasi-one-dimensional Ising ferromagnet CoNbO
Neil J. Robinson, Fabian H. L. Essler, Ivelisse Cabrera +1
We present experimental and theoretical evidence that an interesting quantum many-body effect -- quasi-particle breakdown -- occurs in the quasi-one-dimensional spin-1/2 Ising-like…
Excitations in the quantum paramagnetic phase of the quasi-one-dimensional Ising magnet CoNbO in a transverse field: Geometric frustration and quantum renormalization effects
I. Cabrera, J. D. Thompson, R. Coldea +5
The quasi-one-dimensional (1D) Ising ferromagnet CoNbO has recently been driven via applied transverse magnetic fields through a continuous quantum phase transition from sp…
Neutron scattering study of a quasi-2D spin-1/2 dimer system Piperazinium Hexachlorodicuprate under hydrostatic pressure
Tao Hong, C. Stock, I. Cabrera +5
We report inelastic neutron scattering study of a quasi-two-dimensional S=1/2 dimer system Piperazinium Hexachlorodicuprate under hydrostatic pressure. The spin gap Δ becomes softe…
