# Coherent-State Approach for Majorana representation

@article{Liu2016CoherentStateAF, title={Coherent-State Approach for Majorana representation}, author={H D Liu and Li-bin Fu and Xiaoguang Wang}, journal={arXiv: Quantum Physics}, year={2016} }

By representing a quantum state and its evolution with the majorana stars on the Bloch sphere, the Majorana representation (MR) provide us an intuitive way to study a physical system with SU(2) symmetry. In this work, based on coherent states, we propose a method to establish generalization of MR for a general symmetry. By choosing a generalized coherent state as a reference state, we give a more general MR for both finite and infinite systems and the corresponding star equations are given…
