Characterization of Majorana-Ising phase transition in a helical liquid system
Sudip Kumar Saha, Dayasindhu Dey, Monalisa Singh Roy +2
We map an interacting helical liquid system, coupled to an external magnetic field and s-wave superconductor, to an XYZ spin system, and it undergoes Majorana-Ising transition by t…

A Study of Topological Quantum Phase Transition and Majorana Localization Length for the Interacting Helical Liquid System
Dayasindhu Dey, Sudip Kumar Saha, P. Singha Deo +2
We consider a helical spin liquid system which shows majorana fermion modes at the edge. The interaction between the quasiparticles in this system induces phase transition, Majoran…
