Acceleration of quasi-particle modes in Bose-Einstein condensates

TL;DR

This paper analytically investigates how quasi-particle modes in a Bose-Einstein condensate behave under weak acceleration, revealing that their momentum is squeezed instead of accelerated.

Contribution

It introduces an analytical framework showing that quasi-particle mode momentum undergoes squeezing rather than acceleration in a weakly accelerated Bose-Einstein condensate.

Findings

Quasi-particle mode momentum is squeezed under weak acceleration.

Analytical methods reveal non-intuitive mode dynamics.

Results contrast with classical expectations of acceleration.

Abstract

We analytically examine the dynamics of quasi-particle modes occuring in a Bose-Einstein condensate which is subject to a weak acceleration. It is shown that the momentum of a quasi-particle mode is squeezed rather than accelerated.
