Lippmann-Schwinger Approach for Accurate Photoelectron Wavefunctions and Angle-Resolved Photoemission Spectra from First Principles
Ji Hoon Ryoo, Cheol-Hwan Park
We present a conceptually simple and technically straightforward method for calculating photoelectron wavefunctions that is easily integrable with standard wavefunction-based densi…
Computation of intrinsic spin Hall conductivities from first principles using maximally-localized Wannier functions
Ji Hoon Ryoo, Cheol-Hwan Park, Ivo Souza
We present a method to compute the intrinsic spin Hall conductivity from first principles using an interpolation scheme based on maximally-localized Wannier functions. After obtain…
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…
Bright visible light emission from graphene
Young Duck Kim, Hakseong Kim, Yujin Cho +18
Graphene and related two-dimensional materials are promising candidates for atomically thin, flexible, and transparent optoelectronics. In particular, the strong light-matter inter…
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…
Hidden orbital polarization in diamond, silicon, germanium, gallium arsenide and layered materials
Ji Hoon Ryoo, Cheol-Hwan Park
It was previously believed that the Bloch electronic states of non-magnetic materials with inversion symmetry cannot have finite spin polarizations. However, since the seminal work…
