First-principles modelling for time-resolved ARPES under different pump-probe conditions
Umberto De Giovannini, Shunsuke A. Sato, Hannes Hübener +1
First-principles methods for time-resolved angular resolved photoelectron spectroscopy play a pivotal role in providing interpretation and microscopic understanding of the complex…
Excited-state band structure mapping
M. Puppin, C. W. Nicholson, C. Monney +10
Angle-resolved photoelectron spectroscopy is an extremely powerful probe of materials to access the occupied electronic structure with energy and momentum resolution. However, it r…
Floquet Engineering of Magnetism in Topological Insulator Thin Films
Xiaoyu Liu, Peizhe Tang, Hannes Hübener +3
Dynamic manipulation of magnetism in topological materials is demonstrated here via a Floquet engineering approach using circularly polarized light. Increasing the strength of the…
Simulating terahertz field-induced ferroelectricity in quantum paraelectric SrTiO
Dongbin Shin, Simone Latini, Christian Schafer +5
Recent experiments have demonstrated that light can induce a transition from the quantum paraelectric to the ferroelectric phase of SrTiO. Here, we investigate this terahertz f…
Terahertz driven extremely nonlinear bulk photogalvanic currents in non-resonant conditions
Ofer Neufeld, Nicolas Tancogne-Dejean, Umberto De Giovannini +2
We report on the generation of bulk photocurrents in materials driven by non-resonant bi-chromatic fields that are circularly polarized and co-rotating. The nonlinear photocurrents…
Common microscopic origin of the phase transitions in TaNiS and the excitonic insulator candidate TaNiSe
Lukas Windgätter, Malte Rösner, Giacomo Mazza +5
The structural phase transition in TaNiSe has been envisioned as driven by the formation of an excitonic insulating phase. However, the role of structural and electronic in…
