Idea

The Scherk-Schwarz mechanism (Scherk-Schwarz 79) is the spontaneous supersymmetry breaking by KK-compactification on a circle whose spin structure imposes anti-periodic boundary conditions for fermion fields.

Examples and applications

Witten-Sakai-Sugimoto brane model for quantum chromodynamics

In the Witten-Sakai-Sugimoto model non-supersymmetric QCD is geometrically engineered from the D=5 super Yang-Mills theory on D4-branes by wrapping these on a Scherk-Schwarz circle (Witten 98, p. 19)
