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…
Dispersive dark excitons in van der Waals ferromagnet CrI3
W. He, J. Sears, F. Barantani +11
Spin-flip dark excitons are optical-dipole-forbidden quasiparticles with remarkable potential in optoelectronics, especially when they are realized within cleavable van der Waals m…
Coupling of Electronic Transitions to Ferroelectric Order in a 2D Semiconductor
Chun-Ying Huang, Daniel G. Chica, Zhi-Hao Cui +16
A ferroelectric material often exhibits a soft transvers optical (TO) phonon mode which governs it phase transition. Charge coupling to this ferroelectric soft mode may further med…
Capping effects on spin and charge excitations in parent and superconducting Nd1-xSrxNiO2
S. Fan, H. LaBollita, Q. Gao +19
Superconductivity in infinite layer nickelates Nd1-xSrxNiO2 has so far been achieved only in thin films raising questions on the role of substrates and interfaces. Given the challe…
Magnetically propagating Hund's exciton in van der Waals antiferromagnet NiPS3
