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…
Topological transitions in Ising models
Somenath Jalal, Rishabh Khare, Siddhartha Lal
The thermal dynamics of the two-dimensional Ising model and quantum dynamics of the one-dimensional transverse-field Ising model (TFIM) are mapped to one another through the transf…
Quantum Ising Systems, Edge Modes, and Rabi Lattice
Somenath Jalal
The thesis contains theoretical study of number of systems in low dimension, which are related to quantum Ising model. The main results are emergence of Majorana fermions in conden…
Edge modes in a frustrated quantum Ising chain
Somenath Jalal, Brijesh Kumar
The ground state properties of an Ising chain with nearest () and next-nearest neighbor () interactions in a transverse field are investigated using the density matri…
Quantum Ising dynamics and Majorana-like edge modes in the Rabi lattice model
Brijesh Kumar, Somenath Jalal
The atomic dipoles in the Rabi lattice model exhibit quantum Ising dynamics in the limit of strong atom-photon interaction. It governs the para- to ferro-electric phase transition…
