Momentum-dependent spin selection rule in photoemission with glide symmetry
Ji Hoon Ryoo, Cheol-Hwan Park
We present a comprehensive theory on the spin- and angle-resolved photoemission spectroscopy (SARPES) of materials with glide-mirror symmetry, focusing on the role of glide symmetr…

Breakdown of the Chiral Anomaly in Weyl Semimetals in a Strong Magnetic Field
Pilkwang Kim, Ji Hoon Ryoo, Cheol-Hwan Park
The low-energy quasiparticles of Weyl semimetals are a condensed-matter realization of the Weyl fermions introduced in relativistic field theory. Chiral anomaly, the nonconservatio…

Spin-conserving and reversing photoemission from the surface states of BiSe and Au (111)
Ji Hoon Ryoo, Cheol-Hwan Park
We present a theory based on first-principles calculations explaining (i) why the tunability of spin polarizations of photoelectrons from BiSe (111) depends on the band ind…
