Observation of multipartite spin entanglement in a cuprate chain
S. F. R. TenHuisen, Z. Shen, V. Bhartiya +17
Quantum materials are believed to host highly entangled states of matter, but probing and quantifying such entanglement has long remained experimentally elusive. Here, we use reson…
Disentangling multi-spin dynamic correlations in the Heisenberg spin- chain
V. K . Bhartiya, U. Kumar, T. Kim +8
Higher-order correlations are essential for understanding exotic phases and uncovering universal aspects of quantum dynamics. While inelastic neutron scattering provides well-estab…
Observation of Switchable Chiral Magnons in an Altermagnet
Zheyuan Liu, Hodaka Kikuchi, Zijun Wei +8
Chiral magnons, the quanta of handed spin waves, transport spin angular momentum without energy loss due to Joule heating. The recently discovered altermagnets were proposed to hos…
Quantum control of Hubbard excitons
D. R. Baykusheva, D. P. Carmichael, C. S. Weber +12
Quantum control of the many-body wavefunction is a central challenge in quantum materials research, as it could yield a precise control knob to manipulate emergent phenomena. Floqu…
Altermagnetic and dipolar splitting of magnons in FeF
J. Sears, V. O. Garlea, D. Lederman +2
FeF is a prototypical rutile antiferromagnet recently proposed as an altermagnet, with a magnetic symmetry that permits spin-split electronic bands and chiral magnons. Using ve…
Peierls Transition and Magnetism in a Dirac Semimetal: CaMnBi
Aashish Sapkota, Niraj Aryal, Xiao Hu +9
Dirac semimetals of the form Mn ( alkaline-earth or divalent rare earth; Bi, Sb) host conducting square-net Dirac-electron layers of atoms interleaved with a…
Emergence of low-energy spin waves in superconducting electron-doped cuprates
Kristine M. L. Krighaar, Jeppe J. Cederholm, Ellen M. S. Schriver +11
In order to fully utilize the technological potential of unconventional superconductors, an enhanced understanding of the superconducting mechanism is necessary. In the best perfor…
EuAuSb: An odd-parity helical variation on altermagnetism
J. Sears, Juntao Yao, Zhixiang Hu +7
EuAuSb is a triangular-lattice Dirac semimetal in which a topological Hall effect has been observed to develop in association with a magnetically-ordered phase. Our single-crystal…
Spin pseudogap in Ni-doped SrCuO2
G. Simutis, S. Gvasaliya, M. Mansson +11
The S=1/2 spin chain material SrCuO2 doped with 1% S=1 Ni-impurities is studied by inelastic neutron scattering. At low temperatures, the spectrum shows a pseudogap Δ~ 8 meV, absen…
Spinons in the strongly correlated copper oxide chains in SrCuO2
I. A. Zaliznyak, H. Woo, T. G. Perring +3
We have investigated the spin dynamics in the strongly correlated chain copper oxide SrCuO for energies up to eV using inelastic neutron scattering. We observe an…
Continuum in the spin excitation spectrum of a Haldane chain, observed by neutron scattering in CsNiCl3
I. A. Zaliznyak, S. -H. Lee, S. V. Petrov
The spin excitation continuum, expected to dominate the low-energy fluctuation spectrum in the Haldane spin chain around the Brillouin zone center, q=0, is directly observed by ine…
