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…
Observation of anisotropic dispersive dark exciton dynamics in CrSBr
J. Sears, B. Zager, W. He +15
Many-body excitons in CrSBr are attracting intense interest in view of their highly anisotropic magneto-optical coupling and their potential for novel optical interfaces within spi…
Exploring Quantum Materials with Resonant Inelastic X-Ray Scattering
M. Mitrano, S. Johnston, Young-June Kim +1
Understanding quantum materials -- solids in which quantum-mechanical interactions among constituent electrons yield a great variety of novel emergent phenomena -- is a forefront c…
Magnetically propagating Hund's exciton in van der Waals antiferromagnet NiPS3
W. He, Y. Shen, K. Wohlfeld +9
Magnetic van der Waals (vdW) materials have opened new frontiers for realizing novel many-body phenomena. Recently NiPS3 has received intense interest since it hosts an excitonic q…
Quadrupolar magnetic excitations in an isotropic spin-1 antiferromagnet
A. Nag, A. Nocera, S. Agrestini +5
The microscopic origins of emergent behaviours in condensed matter systems are encoded in their excitations. In ordinary magnetic materials, single spin-flips give rise to collecti…
