Sign control of photocurrents by spin-group-symmetry breaking in altermagnetic insulators
Gastón Blatter, Xiao Zhang, Jeroen van den Brink +2
Controlling physical responses through symmetry breaking is a central paradigm in quantum materials, enabling novel functionalities. Here we determine the effects of spin-group-sym…

Impact of crystal symmetries and Weyl nodes on high-harmonic generation in Weyl semimetal TaAs
Xiao Zhang, Jeroen van den Brink, Jinbin Li
High-harmonic generation (HHG) offers an all-optical approach to discern structural symmetries through its selection rules and probe topological phases with its spectral signatures…

Layer dependent topological phases and transitions in TaRhTe: From monolayer and bilayer to bulk
Xiao Zhang, Ning Mao, Oleg Janson +2
The recently synthesized ternary quasi-2D material TaRhTe is a bulk Weyl semimetal with an intrinsically layered structure, which poses the question how the topology of its ele…
