Collapse in boson-fermion mixtures with all-repulsive interactions

TL;DR

This paper investigates the collapse phenomena in boson-fermion mixtures with purely repulsive interactions, highlighting early and super-slow collapse behaviors caused by pressure from a large fermionic component.

Contribution

It introduces the concept of collapse in all-repulsive boson-fermion mixtures and describes the dynamics of early and super-slow collapse phases.

Findings

Collapse occurs in all-repulsive boson-fermion mixtures due to fermionic pressure.

Identifies early and super-slow collapse regimes.

Provides theoretical description of collapse dynamics.

Abstract

We describe the collapse of the bosonic component in a boson-fermion mixture due to the pressure exerted on them by a large fermionic component, leading to collapse in a system with all-repulsive interactions. We describe the phenomena early collapse and of super-slow collapse of the mixture.
