Josephson junction formed in the wormhole space time from the analysis for the critical temperature of Bose-Einstein condensate

TL;DR

This paper investigates the critical temperature of Bose-Einstein condensates near a wormhole throat and suggests that a Josephson junction-like state always forms there, offering insights into gravitational phenomena.

Contribution

It introduces the concept of a gravitational Josephson junction formed in wormhole spacetime based on BEC behavior near the throat.

Findings

Critical temperature of BEC near wormhole throat is zero.

A Josephson junction-like state always exists near the wormhole throat.

Potential implications for gravitational phenomenology.

Abstract

In this study, considering some gas in the Morris-Thorne traversable wormhole space time, we analyze the critical temperature of the Bose-Einstein condensate in the vicinity of its throat. As a result, we obtain the result that it is zero. Then, from this result, we point out that an analogous state to the Josephson junction is always formed at any temperatures in the vicinity of its throat. This would be interesting as a gravitational phenomenology.
