Clustering-Enhanced Time- and Angle-Resolved Photoemission Study of LaTe: Absence of a Photoinduced Secondary CDW in the Electronic Structure
Gesa-R. Siemann, Davide Curcio, Anders S. Mortensen +9
Optical control offers a compelling route for tailoring material properties on an ultrafast time scale. Ordered states such as charge density waves (CDWs) can be transiently melted…
Spin-orbit coupling induced Van Hove singularity in proximity to a Lifshitz transition in SrRuO
Carolina A. Marques, Philip A. E. Murgatroyd, Rosalba Fittipaldi +19
Van Hove singularities (VHss) in the vicinity of the Fermi energy often play a dramatic role in the physics of strongly correlated electron materials. The divergence of the density…
Dichotomy of electron-phonon interactions in the delafossite PdCoO: From weak bulk to polaronic surface coupling
Gesa-R. Siemann, Philip A. E. Murgatroyd, Tommaso Antonelli +6
The metallic delafossites host ultra-high mobility carriers in the bulk, while at their polar surfaces, intrinsic electronic reconstructions stabilise markedly distinct electronic…
Ultrafast Electronic Structure Engineering in 1-TaS: Role of Doping and Amplitude Mode Dynamics
J. Jayabalan, Jiyu Chen, Laura Pätzold +12
In strongly correlated transition metal dichalcogenides, an intricate interplay of polaronic distortions, stacking arrangement, and electronic correlations determines the nature of…
Avoided metallicity in a hole-doped Mott insulator on a triangular lattice
Chi Ming Yim, Gesa-R. Siemann, Srdjan StavriÄ +9
Doping of a Mott insulator gives rise to a wide variety of exotic emergent states, from high-temperature superconductivity to charge, spin, and orbital orders. The physics underpin…
Covalency, correlations, and inter-layer interactions governing the magnetic and electronic structure of MnSiTe
Chiara Bigi, Lei Qiao, Chao Liu +16
MnSiTe is a rare example of a layered ferrimagnet. It has recently been shown to host a colossal angular magnetoresistance as the spin orientation is rotated from the i…
