Can An Uncertainty Relation Generate A Plasma?

We explore the fundamental idea that there may be a role for the Casimir effect, via an uncertainty relation, in the generation of electron-positron and quark-gluon plasmas. We investigate this concept, reviewing the possible contribution of semi-classical electrodynamics to nuclear interactions, specifically focusing on the Casimir effect at sub-Fermi length scales. The main result is a temperature distance relation, derived from the time-energy uncertainty relation, which can have observable consequences at these extreme scales. From a more general perspective, since the energy-time uncertainty relation appears to be a significant physical quantity, we also provide a brief overview of recent developments in this direction in Sec. 3.2.

Temperature-Distance Relations in Casimir Physics

The Casimir-Lifshitz force arises from thermal and quantum mechanical fluctuations between classical bodies and becomes significant below the micron scale. We explore temperature-distance relations based on the concepts of Wick and Bohr arising from energy-time uncertainty relations. We show that temperature-distance relations similar to those arising from the uncertainty principle are found in various Casimir interactions, with an exact relation occurring in the low-temperature regime when the zero point energy contribution cancels the thermal radiation pressure contribution between two plates.
