The Casimir effect shows that quantum field theory allows the energy density in very small regions of space to be negative relative to the ordinary vacuum energy, and the energy densities cannot be arbitrarily negative as the theory breaks down at atomic distances.
Casimir effect, mass gap generation and (de)confinement Consider now a nonperturbative vacuum of a confining (gauge) theory in which a particle and an antiparticle are attracted to each other by a linear potential at large enough distances.
Aug 6, 2020 · A Lorentz symmetry violation aether-type theoretical model is considered to investigate the Casimir effect and the generation of topological mass associated with self-interacting massive scalar fields obeying Dirichlet, Newman, and mixed boundary conditions on two large and parallel plates.

Oct 18, 2022 · Nature Communications - Experimental studies of the Casimir effect have involved only interactions between two bodies so far. Here, the authors observe a micrometer-thick cantilever under the...
Oct 10, 2020 · 15.1: Casimir effect - forces from nothing. For many quantum systems, such as the harmonic oscillator, there is still some energy associated with the lowest quantum state. This “zero-point” energy is real, and can be measured in the ‘Casimir effect’.
7 - The Casimir Effect. from PART I - Basics. Published online by Cambridge University Press: 22 February 2022. Michel Talagrand. Chapter. Get access. Cite. Summary. Two well-polished metallic plates very close to each other in a vacuum feel a (slight) mutual attraction.
Mar 19, 2024 · Further investigations of the Casimir effect at high-temperatures/short-range regimes may offer more evidence for its potential influence in both meson and atom–atom physics. The modern research on van der Waals, Lifshitz, and Casimir interactions was pioneered by Ninham and Parsegian more than 50 years ago.
