Photostationary Lifshitz transition in High Tc superconductor Bi2Sr2CaCu2O8+δ

Ji Dai, Lukas Hellbrück, Michele Puppin +12

To date, controlling the steady-state electronic band structure in high-Tc cuprate superconductors has been achieved primarily through chemical doping or magnetic fields. Here, we…

Discerning ground state and photoemission-induced spin textures in altermagnetic -MnTe

D. A. Usanov, S. W. D'Souza, A. Dal Din +12

The recently discovered class of altermagnets provide a physical realization of an unconventional compensated magnetic phase with a higher partial-wave type of ordering, reminiscen…

Large differential attosecond delays in solid state photoemission

Andreas Gebauer, Walter Enns, Sergej Neb +11

Time-resolved photoelectron spectroscopy provides access to the electronic structure and non-equilibrium electron dynamics in matter. At solid surfaces photoemission dynamics can b…

Unconventional relativistic spin polarization of electronic bands in an altermagnet

A. Dal Din, D. A. Usanov, L. Å mejkal +22

Altermagnetism is a recently identified phase with a d, g or i-wave spin symmetry of magnetic ordering. Its discovery opens new research fronts at intersections of magnetism and sp…

Floquet topological state induced by light-driven band inversion in SnTe

F. Chassot, G. Kremer, A. Pulkkinen +7

High intensity coherent light can dress matter, realizing new hybrid phases that are not accessible in equilibrium. This effect results from the coherent interaction between Bloch…
