Observation of correlated plasmons in low-valence nickelates

Using resonant inelastic x-ray scattering, researchers detected correlated plasmons in the low-valence nickelate Pr4Ni3O8, revealing that these collective excitations are more heavily damped, slower, and temperature-softening compared to cuprates, thereby highlighting distinct charge-screening mechanisms and limiting direct analogies between the two material families.

Valley Valves at Domain Walls in Symmetry-Broken Rhombohedral Graphene

This paper demonstrates that in symmetry-broken rhombohedral graphene, valley domain walls act as impenetrable barriers in the metallic regime and require intervalley mixing to support supercurrents in the superconducting phase, highlighting the critical role of intervalley hybridization in governing transport across these boundaries.

Novel dynamical excitations and roton-based measurement of Cooper-pair momentum in a two-dimensional Fulde-Ferrell-Larkin-Ovchinnikov superfluid on optical lattices

This paper theoretically investigates the dynamical excitations of a two-dimensional spin-polarized attractive Hubbard model on optical lattices to identify a roton-based protocol for measuring the center-of-mass momentum of Cooper pairs during the transition from a BCS to an FFLO superfluid.
