# Landauer bound for erasure using non-ideal gas

## TL;DR

This paper investigates how inter-particle interactions in a non-ideal gas can modify the Landauer bound for information erasure, showing that the entropy cost can be reduced with specific interactions.

## Contribution

It extends the Landauer principle to non-ideal gases with interactions, demonstrating a potential reduction in entropy production during erasure.

## Key findings

- Interaction via square-well potential lowers entropy bound
- Non-ideal gas interactions can reduce thermodynamic costs
- Modification of Landauer bound depends on interaction type

## Abstract

Landauer principle states that erasure of $N$ bit information requires an entropic cost of $Nk_B \ln 2$. This fact can easily be demonstrated by relaxation of an ideal gas consisting of $N$ particles inside a fixed volume. In this paper we discuss the modification of Landauer bound when we use non-ideal gas with inter-particle interactions for erasure procedure. We have found that the bound on the entropy production can be lowered when the interaction between particles is square-well potential.
