Floquet Bosonic Kitaev Chain
Raditya Weda Bomantara
We propose a class of periodically driven (Hermitian) modified bosonic Kitaev chains that effectively hosts rich nonHermitian Floquet topological phenomena. Two particular models a…
Zero and Nonzero Energy Majorana Modes in an Extended Kitaev Chain
Mohammad Ghuneim, Raditya Weda Bomantara
This paper studies an extended Kitaev chain with three sublattices per unit cell. This extended version is obtained by hybridizing a modified Su-Schrieffer-Heeger model featuring t…
NonHermitian Topological Phases in a Hermitian Modified Bosonic Kitaev Chain
Raditya Weda Bomantara, Ibsal Assi, J. P. F. LeBlanc +1
We present a modification to the bosonic Kitaev chain that, despite being Hermitian, supports both nonHermitian skin effect and nontrivial topological edge modes in its excitation…
Anomalous topological edge modes in a periodically-driven trimer lattice
Mohammad Ghuneim, Raditya Weda Bomantara
Periodically driven systems have a longstanding reputation for establishing rich topological phenomena beyond their static counterpart. In this work, we propose and investigate a p…
