Random surface fields in a Bose-Einstein condensate are claimed to generate non-local effective interactions that mimic Euclidean wormholes, with a disorder-induced Casimir pressure as the leading consequence.

abstract
We propose a useful integral representation of the quenched free energy which is applicable to any random systems. Our formula involves the generating function of multi-boundary correlators, which can be interpreted on the bulk gravity side as spacetime D-branes introduced by Marolf and Maxfield in [arXiv:2002.08950]. As an example, we apply our formalism to the Airy limit of the random matrix model and compute its quenched free energy under certain approximations of the generating function of correlators. It turns out that the resulting quenched free energy is a monotonically decreasing function of the temperature, as expected.

Analog model for Euclidean wormholes: Bose-Einstein condensate with dirty surfaces
