An investigation of the two-dimensional non-Hermitian Su-Schrieffer-Heeger Model
Udai Prakash Tyagi, Partha Goswami
This communication presents an examination of a two-dimensional, non-Hermitian Su -Schrieffer-Heeger (SSH) model, which is differentiated from its conventional Hermitian counterpar…
Two-dimensional non-Hermitian Su-Schrieffer-Heeger Model
Udai Prakash Tyagi, Partha Goswami
A particle-hole symmetry protected 2D non-Hermitian Su-Schrieffer-Heeger (SSH) model is investigated. This version differs from the usual Hermitian version by the inclusion of gain…
Anomalous Nernst Effect in Ferromagnetic Weyl Semimetal
Udai Prakash Tyagi, Partha Goswami
In a three-dimensional Dirac semimetal the time reversal symmetry (TRS) or the inversion symmetry (IS) is not broken. With either of these symmetries broken, the Dirac points in th…
Theoretical Investigation of the Periodic Anderson Hamiltonian of Samarium Hexaboride
Partha Goswami, Udai Prakash Tyagi
The periodic Anderson Hamiltonian of the bulk samarium hexaboride is investigated in this article assuming the presence of ferromagnetic impurities (FM). The problem of large on-si…
Some information on acoustic topological insulator
Partha Goswami, Udai Prakash Tyagi
In this exceedingly short review article, we have provided some information on acoustic topological insulator for pedagogical purpose. Since, intrinsically acoustic systems do not…
On Weyl Nodes in Ferromagnetic Weyl Semimetal
Udai Prakash Tyagi, Partha Goswami
The ferromagnetic Weyl semimetals, such as Co3Sn2S2, feature pairs of Weyl points characterized by the opposite chiralities.We model this type of semimetals by the inversion symmet…
