Arbitrary Chern number generation in the three-band model from momentum space
Soo-Yong Lee, Jin-Hong Park, Gyungchoon Go +1
A simple, general rule for generating a three-band model with arbitrary Chern numbers is given. The rule is based on the idea of monopole charge-changing unitary operations and can…
Exploration of the helimagnetic and skyrmion lattice phase diagram in Cu2OSeO3 using magnetoelectric susceptibility
A. A. Omrani, J. S. White, K. Prša +6
Using SQUID magnetometry techniques, we have studied the change in magnetization versus applied ac electric field, i.e. the magnetoelectric (ME) susceptibility dM/dE, in the chiral…
Microscopic mechanism for asymmetric charge distribution in Rashba-type surface states and the origin of the the energy splitting scale
Beomyoung Kim, Panjin Kim, Wonsig Jung +9
Microscopic mechanism for the Rashba-type band splitting is examined in detail. We show how asymmetric charge distribution is formed when local orbital angular momentum (OAM) and c…
Soliton Defects in One-dimensional Topological Three-band Hamiltonian
Gyungchoon Go, Kyeong Tae Kang, Jung Hoon Han
Defect formation in the one-dimensional topological three-band model is examined within both lattice and continuum models. Classic results of Jackiw-Rebbi and Rice-Mele for the sol…
Emergent p-wave Kondo Coupling in Multi-Orbital Bands with Mirror Symmetry Breaking
Jun Won Rhim, Jung Hoon Han
We examine Kondo effect in the periodic Anderson model for which the conduction band is of multi-orbital character and subject to mirror symmetry breaking field imposed externally.…
