Flat band and Bulk-Boundary correspondence in a non-Hermitian trimerized lattice model with generic boundary conditions
Supriyo Ghosh, Pijush K. Ghosh, Shreekantha Sil
We consider a Su-Schrieffer-Heeger(SSH)-type trimer model with next-nearest-neighbor(NNN) interaction and balanced loss-gain(BLG) to study the combined effect of lattice symmetries…

Interaction and non-Hermiticity controlled transmission in extended Su-Schrieffer-Heeger models
Syeda Rafisa Rahaman, Shreekantha Sil, Nilanjan Bondyopadhaya
We study the transport characteristics of an extended version of the Su-Schrieffer-Heeger (SSH) model with next-nearest-neighbor (NNN) interactions and non-Hermitian onsite energie…
