Realization of 2-channel Kondo effect in a junction of three quantum Ising chains

It is shown that a junction of three quantum Ising chains ($\mathrm{\Delta }$-junction) can be described as the 2-channel Kondo model in a box which size is of the order of the Ising model correlation length with spin S=1/2 localized at the junction. The local spin is composed of the zero energy boundary Majorana modes of the Ising models.
