Multiphoton Fingerprints of Altermagnetic Spin Splittings
Sayed Ali Akbar Ghorashi, Andrew M. Rappe
We systematically investigate multiphoton absorption as a polarization-resolved nonlinear optical probe of planar altermagnets (ALMs). We show that the angular harmonic of the alte…

Field-unmasked quantum geometry in a symmetry-forbidden photocurrent
Bumseop Kim, Aaron M. Burger, Zhenbang Dai +6
Frequency- and polarization-resolved photocurrents provide a sensitive probe of hidden symmetry and band geometry in quantum materials. Here we study a chiral cubic sillenite whose…
