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…
Quantum anomalous Hall effect induced by circularly polarized light on samarium hexaboride surface
Udai Prakash Tyagi, Partha Goswami
We examine a time-dependent, surface Hamiltonian for the 3D compound samarium hexaboride based on the slave boson protocol linked version of the periodic Anderson model reported ea…
