Site-Specific Orbital Symmetry Breaking in Epitaxial Graphene on Silicon Carbide
Vinod K. Paidi, Yves Joly, Alex Taekyung Lee +5
The epitaxial graphene grown on SiC interface has been the subject of tremendous research efforts to control its electronic transport properties in the quest for graphene electroni…
Delocalized polaron and Burstein-Moss shift induced by Li in -: DFT+DMFT study
Huu T. Do, Alex Taekyung Lee, Hyowon Park +1
We performed density functional theory (DFT)+ and dynamical mean field theory (DMFT) calculations with continuous time quantum Monte Carlo impurity solver to investigate the ele…
Spin-orbit interaction enabled electronic Raman scattering from charge collective modes
Surajit Sarkar, Alexander Lee, Girsh Blumberg +1
Electronic Raman scattering in the fully symmetric channel couples to the charge excitations in the system, including the plasmons. However, the plasmon response has a spectral wei…
Effect of Off-Diagonal Elements in Wannier Hamiltonian on DFT+DMFT for low-symmetry material: Study of LiMnO
Alex Taekyung Lee, Hyowon Park, Anh T. Ngo
We study the effect of the off-diagonal elements of the Wannier Hamiltonian on the electronic structure of low-symmetry material LiMnO (), using dynamical mean field…
Spin and electronic excitations in atomic chains on Au(111) substrates
David W. Facemyer, Naveen K. Dandu, Alex Taekyung Lee +3
High spin systems, like those that incorporate rare-earth elements (REEs), are increasingly relevant in many fields. Although research in such systems is sparse, the large Hil…
Origin of the orbital polarization of Co in LaCoTiO and (LaCoO)+(LaTiO) : a DFT+ and DMFT study
Alex Taekyung Lee, Hyowon Park, Sohrab Ismail-Beigi
The unequal electronic occupation of localized orbitals (orbital polarization), and associated lowering of symmetry and degeneracy, play an important role in the properties of tran…
