Casimir Effect in Yang-Mills Theory in D=2+1

Area of Science:

• Theoretical Physics
• Quantum Field Theory
• Condensed Matter Physics

Background:

• The Casimir effect describes a physical force arising from quantum field fluctuations.
• Non-Abelian gauge theories are fundamental to understanding particle interactions.
• Previous studies have not explored the Casimir effect within these complex theories.

Purpose of the Study:

• To investigate the Casimir effect in non-Abelian gauge theory for the first time.
• To explore the behavior of chromoelectric conductors under quantum vacuum influence.
• To identify novel phenomena arising from the interplay of gauge theory and vacuum effects.

Main Methods:

• First-principles numerical simulations in two spatial dimensions.
• Zero-temperature quantum field theory calculations.
• Analysis of conductor spacing and vacuum properties.

Main Results:

• Observed attraction between closely spaced perfect chromoelectric conductors.
• Quantified a small anomalous scaling dimension for the attractive force.
• Discovered a new Casimir mass, distinct from the glueball mass, suppressing attraction at large separations.

Conclusions:

• The Casimir effect in non-Abelian gauge theory exhibits unique characteristics, including a novel Casimir mass.
• The vacuum's backreaction to chromoelectric conductors induces a phase transition towards color deconfinement.
• This work provides foundational insights into quantum vacuum phenomena in non-Abelian theories.
