Multi-criticality and long-range effects in non-Hermitian topological models
Y R Kartik, Sujit Sarkar
Long-range effects induce some interesting behavior and considered as a gateway to understand the non-local behavior in the quantum systems. Especially, the long-range topological…
A study of topological characterization and symmetries for a quantum simulated Kitaev chain
Y R Kartik, Ranjith R Kumar, S Rahul +1
An attempt is made to quantum simulate the topological classification, such as winding number, geometric phase and symmetry properties for a quantum simulated Kitaev chain. We find…
Multi-critical topological transition at quantum criticality
Ranjith R Kumar, Y R Kartik, S Rahul +1
The investigation and characterization of topological quantum phase transition between gapless phases is one of the recent interest of research in topological states of matter. We…
A Study of Berry Connection and Complex Analysis for Topological Characterization
Y R Kartik, Rahul S, Ranjith Kumar R +1
We study and present the results of Berry connection for the topological states in quantum matter. The Berry connection plays a central role in the geometric phase and topological…
An Interplay of Topology and Quantized Geometric Phase for two Different Symmetry-Class Hamiltonians
Rahul S, Ranjith Kumar R, Y R Kartik +2
Study of symmetry, topology and geometric phase can reveal many new and interesting results on the topological states of matter. Here we present a completely new and interesting re…
