# Interference of Particles with Fermionic Internal Degrees of Freedom

## TL;DR

This paper explores how fermionic particles interfere in a Mach–Zehnder interferometer when influenced by classical and non-classical controls.

## Contribution

The study introduces new control strategies to understand how internal fermion–fermion interactions affect interference patterns.

## Key findings

- Classical controls alter interference patterns in predictable ways.
- Non-classical controls reveal complex dependencies on internal fermion interactions.
- The results suggest potential for probing quantum correlations in fermionic systems.

## Abstract

The interference of fermionic particles, specifically molecules comprising a small number of fermions, in a Mach–Zehnder interferometer is being investigated under the influence of both classical and non-classical external controls. The aim is to identify control strategies that can elucidate the relationship between the interference pattern and the characteristics of internal fermion–fermion interactions.
