Macroscopically degenerate flat bands (FB) in periodic lattices host compact localized states
which appear due to destructive interference and local symmetry. Interference provides a …

We suggest a simple method to engineer a tight-binding quantum network based on proper
coupling to an auxiliary non-Hermitian cluster. In particular, it is shown that effective complex …

We theoretically investigate a topological Kitaev chain connected to a double quantum-dot
(QD) setup hybridized with metallic leads. In this system we observe the emergence of two …

By using first principle calculations we have studied the magnetic, electronic and transport
properties of zigzag-graphene nanoribbon (zGNR) with a topological line defect (LD) …

In this paper, we study the effect of PT-symmetric complex potentials on the transport
properties of one non-Hermitian system, which is formed by the coupling between a triple …

We report on a theoretical investigation of the interplay between vacuum fluctuations,
Majorana quasiparticles (MQPs), and bound states in the continuum (BICs) by proposing a …

Majorana-induced Andreev reflection (AR) is theoretically investigated by considering the
interplay between two AR channels, each of which is formed by the lead and its coupled …

Here, the quantization of Dirac fermions in lithographically defined graphene
nanoconstrictions is studied. Quantized conductance is observed in single nanoconstrictions …

We explore theoretically the formation of bound states in the continuum (BICs) in graphene
hosting two collinear adatoms situated at different sides of the sheet and at the center of the …

The present paper casts light upon the performance of an armchair graphene nanoribbon
(AGNR) field effect transistor in the presence of one-dimensional topological defects. The …
