X-ray magnetic circular dichroism and resonant inelastic X-ray scattering explained: role of many-body correlation and valence fluctuations
Beom Hyun Kim, Sang-Jun Lee, H. Huang +12
X-ray magnetic circular dichroism (XMCD) and resonant inelastic X-ray scattering with magnetic circular dichroism (RIXS-MCD) provide unparalleled insights into the electronic and m…
Quantum Geometry and Topology of Bulk Plasmons in Weyl Metals
Hong-Yi Xie, Peter Abbamonte, Bruno Uchoa
We address the quantum geometric structure of plasmons in Fermi surfaces enclosing a topological charge. We demonstrate that Weyl fermion plasmons have monopole structure, are topo…
Plasmon-driven exciton formation in a non-equilibrium Fermi liquid
Rishi Acharya, Eli Gerber, Nina Bielinski +13
Collective modes in Fermi liquids are usually regarded as dissipation channels that relax electronic excitations through Landau damping. Whether such modes can instead mediate the…
Kondo driven suppression of charge density wave in Van der Waals material UTe
Justin Shotton, Jiahui Zhu, David Martinez +22
Competing electronic instabilities lie at the heart of emergent phenomena in quantum materials. In low-dimensional metals, Fermi-surface nesting can drive charge density wave (CDW)…
Reexamining the strange metal charge response with transmission inelastic electron scattering
Niels de Vries, Eric Hoglund, Dipanjan Chaudhuri +8
The strange metal remains one of the great unsolved problems for 21st century science. Since the early development of the marginal Fermi liquid phenomenology, it has been clear tha…
Fundamental Tests of Quantum Geometric Bounds in Ionic and Covalent Insulators using Inelastic X-Ray Scattering
David BaÅut, Barry Bradlyn, Marcus D. Collins +1
Quantum geometry underlies many fundamental properties of materials, but it has remained largely inaccessible to direct experiment. Here we demonstrate that inelastic x-ray scatter…
