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…
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…
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…
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…
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…
Magnetism and Peierls distortion in 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…
