Collective spin excitations in trilayer nickelate LaNiO
Ying Chan, Yuehong Li, Yujie Yan +14
Ruddlesden-Popper (RP) nickelates have recently emerged as a new family of high-temperature superconductors. In bilayer RP nickelates, magnetic excitations with large exchange coup…
Lattice-charge coupling in a trilayer nickelate with intertwined density wave order
Xun Jia, Yao Shen, Harrison LaBollita +16
Intertwined charge and spin correlations are ubiquitous in a wide range of transition metal oxides and are often perceived as intimately related to unconventional superconductivity…
Witnessing Quantum Entanglement Using Resonant Inelastic X-ray Scattering
Tianhao Ren, Yao Shen, Marton Lajer +9
Although entanglement is both a central ingredient in our understanding of quantum many-body systems and an essential resource for quantum technologies, we only have a limited abil…

Intertwined dipolar and multipolar order in the triangular-lattice magnet TmMgGaO
Yao Shen, Changle Liu, Yayuan Qin +6
A phase transition is often accompanied by the appearance of an order parameter and symmetry breaking. Certain magnetic materials exhibit exotic hidden-order phases, in which the o…
Coexistence of ferromagnetic and stripe-type antiferromagnetic spin fluctuations in YFeGe

Heavily electron-doped iron-selenide (HEDIS) high-transition-temperature (high-) superconductors, which have no hole Fermi pockets, but have a notably high …
Evidence for a spinon Fermi surface in a triangular lattice quantum spin liquid candidate
Yao Shen, Yao-Dong Li, Hongliang Wo +16
A quantum spin liquid is an exotic quantum state of matter in which spins are highly entangled and remain disordered down to zero temperature. Such a state of matter is potentially…
