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…

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…

Topological Phases of Tight-Binding Trimer Lattice in the BDI Symmetry Class
Mohammad Ghuneim, Raditya Weda Bomantara
In this work, we theoretically study a modified Su-Schrieffer-Heeger (SSH) model in which each unit cell consists of three sites. Unlike existing extensions of the SSH model which…
