title: Majorana fermion realization of a two-channel Kondo effect in a junction of three quantum Ising chains.
abstract: It is shown that a junction of three critical quantum Ising chains (Delta junction) can be described as a two-channel Kondo model with a spin S=1/2 localized at the junction, which is composed of the respective Ising, zero energy boundary Majorana modes.
