Evolution of quasiparticle edge states with Hubbard interaction in Rice-Mele chain
Jyoti Bisht, Brijesh Kumar
We study the behaviour of edge states in Rice-Mele model with Hubbard interaction, U , at half-filling using density matrix renormalization group, exact diagonalization and effecti…

Theoretical investigation of quantum oscillations of specific heat in Kondo insulators
Arnav Pushkar, Brijesh Kumar
The electronic specific heat of Kondo insulators in magnetic field is studied for the half-filled Kondo lattice model on simple cubic lattice using a low-temperature theory in Kuma…

Transmigration of Edge States with Interaction in Su-Schrieffer-Heeger Chain
Jyoti Bisht, Somenath Jalal, Brijesh Kumar
The effect of Hubbard and Kondo interactions on the edge states in the half-filled Su-Schrieffer-Heeger chain of electrons is investigated by studying the behaviour of charge quasi…
