Stable topological edge states in a non-Hermitian four-band model
Yüce, C. (Amer Physical Soc, 2018)We introduce a one-dimensional non-Hermitian four-band tight-binding lattice system. We find stable topological edge states protected by particle-hole and parity-time symmetries. We show that a topological phase appears ... -
Super Bloch oscillation in a PT symmetric system
Türker, Z.; Yüce, C. (Elsevier Science BV, 2016)Wannier-Stark ladder in a PT symmetric system is generally complex that leads to amplified/damped Bloch oscillation. We show that a non-amplified wave packet oscillation with very large amplitude can be realized in a ... -
Topological phase in a non-Hermitian PT symmetric system
Yüce, C. (Elsevier Science BV, 2015)In this work, we consider a tight binding lattice with two non-Hermitian impurities. The system is described by a non-Hermitian generalization of the Aubry-Andre model. We show that there exists topologically nontrivial ...
