It is argued that thick domain wall junction may be formed during heavy ion collisions and play the role of a trap for charged quasi-particles. Confinement is lost inside the trap of a finite size. There exists a critical size of the stable trap, beyond which the emerging tachyonic gluon modes destroy it.

The paper is organized as follows. Section II is devoted to the domain wall network construction. The spectrum of scalar color charged field in the background of infinitely thin domain wall is discussed in section III. In the fourth section we discuss the chromomagnetic trap formation and evaluate the spectrum and eigenmodes of the color charged scalar, vector and spinor quasiparticles inside the trap.

The calculation of the effective quantum action for the Abelian (anti-)self-dual homogeneous gluon field within the functional renormalization group approach [@Pawlowski] has indicated that this configuration is a serious candidate for the role of global minimum of QCD effective action and has enhanced the older one-loop results [@Minkowski; @Leutwyler; @Pagels]. The functional RG result also supported conclusions of [@NK1; @NG2011] based on the Ginzburg-Landau type effective
