Magnon-Mediated Indirect Exciton Condensation through Antiferromagnetic Insulators
Øyvind Johansen, Akashdeep Kamra, Camilo Ulloa +2
Electrons and holes residing on the opposing sides of an insulating barrier and experiencing an attractive Coulomb interaction can spontaneously form a coherent state known as an i…
Nonlocal Spin Transport as a Probe of Viscous Magnon Fluids
Camilo Ulloa, A. Tomadin, J. Shan +3
Magnons in ferromagnets behave as a viscous fluid over a length scale, the momentum-relaxation length, below which momentum-conserving scattering processes dominate. We show theore…
Magnon spin Hall magnetoresistance of a gapped quantum paramagnet
Camilo Ulloa, R. A. Duine
Motivated by recent experimental work, we consider spin transport between a normal metal and a gapped quantum paramagnet. We model the latter as the magnonic Mott-insulating phase…
Piezospintronic effect in honeycomb antiferromagnets
Camilo Ulloa, Roberto E. Troncoso, Scott A. Bender +2
The emission of pure spin currents by mechanical deformations, the piezospintronic effect, in antiferromagnets is studied. We characterize the piezospintronic effect in an antiferr…
Soliton-like magnetization textures in non-collinear antiferromagnets
Camilo Ulloa, A. S. Nunez
We show that proper control of magnetization textures can be achieved in noncollinear antiferromagnets. This opens the versatile toolbox of domain-wall manipulation in the context…
Antiferromagnetic Magnonic Crystals
Roberto E. Troncoso, Camilo Ulloa, Felipe Pesce +1
We describe the features of magnonic crystals based upon antiferromagnetic elements. Our main results are that with a periodic modulation of either magnetic fields or system charac…
