The most striking example of vacuum fluctuations affecting experiments

Click For Summary
SUMMARY

The discussion centers on the impact of quantum field theory (QFT) vacuum state fluctuations on experimental results in condensed matter physics, particularly in the context of cuprate superconductors. Participants emphasize the significance of quantum criticality, where electron interactions with the vacuum deviate from classical predictions. The conversation highlights the need for specific examples and references to peer-reviewed publications that illustrate these phenomena. The request for shared resources underscores the collaborative nature of the scientific community in addressing complex topics.

TL;DR
What do you think is the most striking example of vacuum fluctuations affecting the results of an experiment?
This is a question for experimentalists working in Condensed Matter Physics. What do you think is the most striking example of QFT vacuum state fluctuations affecting the results of an experiment?

I have vague memory of reviewing some abstracts about quantum criticality in cuprate superconductors. The results were differing from classical predictions in ways explained by electron interactions with the vacuum. But I have since lost all my links to them. Would be happy to see what you have.

Yeah that's fine and all. I'm looking for some examples of how the vacuum state plays a role in quantum criticality. I remember reading publications about cuprate superconductors from peer-reviewed journals. I just have lost all of my notes and bookmarks in the hustle-bustle of life over the years. I was just wondering if anyone on the forum has any of those kinds of experiments "at their fingertips".
