TL;DR

This paper applies the flow-equations method to analytically demonstrate the emergence of dispersion in local bosons within a hybridized boson-fermion model.

Contribution

It introduces an analytical approach using flow-equations to study dispersion phenomena in a hybrid boson-fermion system.

Findings

Dispersion occurs for local bosons in the model.

Flow-equations method effectively analyzes hybridized systems.

Analytical results support the understanding of boson behavior.

Abstract

Using the flow-equations method we showed analytically the occurence of dispersion for the local bosons in a model of hybridized of local bosons and fermions.
