In spintronics, the two main approaches to actively control electrons' spin involve static magnetic or electric fields. An alternative avenue relies on use of optical fields generate currents, which can bolster spin-device performance, allowing for faster and more efficient logic. To date, research has mainly focused injection currents through photogalvanic effect, little is known about direct intrinsic spin-splitting. explore manipulation a material's properties, we consider Rashba effect....
We present a generic procedure for quantifying the interplay of electronic and lattice degrees freedom in photodoped insulators through comparative analysis theoretical many-body simulations time- angle-resolved photoemission spectroscopy (TR-ARPES) transient response candidate excitonic insulator ${\mathrm{Ta}}_{2}\mathrm{Ni}{\mathrm{Se}}_{5}$. Our demonstrates that electron-electron interactions dominate electron-phonon ones. In particular, detailed TR-ARPES spectrum enables clear...
High-temperature superconducting cuprates exhibit an intriguing phenomenology for the low-energy elementary excitations. In particular, unconventional temperature dependence of coherent spectral weight (CSW) has been observed in phase by angle-resolved photoemission spectroscopy (ARPES), both at antinode where d-wave paring gap is maximum, as well along gapless nodal direction. Here, we combine equilibrium and time-resolved ARPES to track dependent meltdown CSW Bi-based with unprecedented...
We present the development of a versatile apparatus for 6.2 eV laser-based time and angle-resolved photoemission spectroscopy with micrometer spatial resolution (time-resolved μ-ARPES). With combination tunable down to ∼11 μm, high energy (∼11 meV), near-transform-limited temporal (∼280 fs), 1.55 pump fluence up 3 mJ/cm2, this time-resolved μ-ARPES system enables measurement ultrafast electron dynamics in exfoliated inhomogeneous materials. demonstrate performance our by correlating spectral...

We present the development of a versatile apparatus for 6.2 eV laser-based time and angle-resolved photoemission spectroscopy with micrometer spatial resolution (time-resolved $\mu$-ARPES). With combination tunable down to $\sim$11 $\mu$m, high energy ($\sim$11 meV), near-transform-limited temporal ($\sim$280 fs), 1.55 pump fluence up $\sim$3 mJ/cm$^2$, this time-resolved $\mu$-ARPES system enables measurement ultrafast electron dynamics in exfoliated inhomogeneous materials. demonstrate...
In article number 2006301, Satya N. Guin, Claudia Felser, and co-workers report a layered topological nodal-line magnet MnAlGe, which is composed of magnetic Mn square-net layers that are separated by nonmagnetic Al–Ge spacers. The material exhibits large anomalous Hall conductivity driven the unique 2D Berry curvature distribution. From this work search for new magnets exploration magnetism properties enabled.
