Direct view of exciton and carrier dynamics in twisted bilayer graphene
Gianmarco Gatti, Anders S. Mortensen, Zhihao Jiang +12
Twisted bilayer graphene (tBLG) on H-intercalated SiC (twist angle of ) is studied by position\mbox{-}, time\mbox{-}, and angle-resolved photoemission spectroscopy…
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…
Line shapes in time- and angle-resolved photoemission spectroscopy explored by machine learning
Tami C. Meyer, Gesa-R. Siemann, Paulina Majchrzak +6
Time- and angle-resolved photoemission spectroscopy is a powerful technique for investigating the dynamics of excited carriers in quantum materials. Typically, data analysis procee…
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 Stavrić +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…
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…
Hierarchy of Lifshitz transitions in the surface electronic structure of SrRuO under uniaxial compression
Edgar Abarca Morales, Gesa-R. Siemann, Andela Zivanovic +12
We report the evolution of the electronic structure at the surface of the layered perovskite SrRuO under large in-plane uniaxial compression, leading to anisotropic $B_{1g}…
The planar triangular magnet AgCrSe: magnetic frustration, short range correlations, and field tuned anisotropic cycloidal magnetic order
M. Baenitz, M. M. Piva, S. Luther +25
Our studies evidence an anisotropic magnetic order below ~K. Susceptibility data in small fields of about 1~T reveal an antiferromagnetic (AFM) order for , whe…
