# Testing Continuous Spontaneous Localization with Fermi liquids

## TL;DR

This paper provides a comprehensive analysis of the Continuous Spontaneous Localization (CSL) collapse model applied to Fermi liquids, exploring both white and non-white noise scenarios and their astrophysical implications.

## Contribution

It introduces a detailed treatment of the CSL model for Fermi liquids, extending previous work to include non-white noise and astrophysical applications.

## Key findings

- Derived bounds on collapse parameters from astrophysical sources
- Extended CSL model analysis to non-white noise scenarios
- Provided theoretical framework for experimental tests of collapse models

## Abstract

Collapse models describe phenomenologically the quantum-to-classical transition by adding suitable nonlinear and stochastic terms to the Schroedinger equation, thus (slightly) modifying the dynamics of quantum systems. Experimental bounds on the collapse parameters have been derived from various experiments involving a plethora of different systems, from single atoms to gravitational wave detectors. Here, we give a comprehensive treatment of the Continuous Spontaneous Localization (CSL) model, the most studied among collapse models, for Fermi liquids. We consider both the white and non-white noise case. Application to various astrophysical sources is presented.
