Backscattering of topologically protected helical edge states by line defects
Mohadese Karimi, Mohsen Amini, Morteza Soltani +1
The quantization of conductance in the presence of non-magnetic point defects is a consequence of topological protection and the spin-momentum locking of helical edge states in two…
Rigorous analysis of the topologically protected edge states in the quantum spin Hall phase of the armchair ribbon geometry
Mozhgan Sadeghizadeh, Morteza Soltani, Mohsen Amini
Studying the edge states of a topological system and extracting their topological properties is of great importance in understanding and characterizing these systems. In this paper…
Explicit derivation of the chiral and (generic) helical edge states for the Kane-Mele model: Closed expressions for the wave function, dispersion relation, and spin rotation
Fatemeh Rahmati, Mohsen Amini, Morteza Soltani +1
While one of the most important and intriguing features of the topological insulators is the presence of edge states, the closed-form expressions for the edge states of some famous…
Multibody expansion of the local integrals of motion: How many pairs of particle-hole do we really need to describe the quasiparticles in the many-body localized phase?
Z. Gholami, M. Amini, M. Soltani +1
The emergent integrability in a many-body localized (MBL) system can be well characterized by the existence of the complete set of local integrals of motion (LIOMs). Such exactly c…
Enhanced thermoelectric efficiency of zigzag bilayer phosphorene nanoribbon; edge states engineering
Shima Sodagar, Hossein Karbaschi, Morteza Soltani +1
We theoretically investigate the thermoelectric properties of zigzag bilayer phosphorene nanoribbons (ZBPNR). We first, draw an analogy between the extended Su-Schrieffer-Heeger (S…
Thermoelectric properties of armchair phosphorene nanoribbons in the presence of vacancy-induced impurity band
Mohsen Rezaei, Hossein Karbaschi, M. Amini +2
Armchair phosphorene nanoribbons (APNRs) are known to be semiconductors with an indirect bandgap. Here, we propose to introduce new states in the gap of APNRs by creating a periodi…
