Boson-Fermion pairing in a Boson-Fermion environment

TL;DR

This paper explores the formation of stable boson-fermion pairs within a boson-fermion environment, revealing a new type of correlated pairs that significantly alter the Fermi surface, with potential implications across various physical systems.

Contribution

It introduces a novel pairing mechanism for boson-fermion pairs in a B-F environment, leading to a new correlated Fermi gas with a modified Fermi surface.

Findings

Stable strongly correlated B-F pairs can form within the continuum.

The correlated B-F pairs create a new Fermi gas with a modified Fermi surface.

Interaction between like particles is neglected in this initial study.

Abstract

Propagation of a Boson-Fermion (B-F) pair in a B-F environment is considered. The possibility of formation of stable strongly correlated B-F pairs, embedded in the continuum, is pointed out. The new Fermi gas of correlated B-F pairs shows a strongly modified Fermi surface. The interaction between like particles is neglected in this exploratory study. Various physical situations where our new pairing mechanism could be of importance are invoked.
