Resumen:
We study a Frustration-induced separable ground state in a bilayer-honeycomblattice antiferromagnet. Using a combination of numerical techniques, the quantumphase diagram is obtained. Around a particular line in the parameter space, the groundstate can be exactly determined and consists in a dimer phase. Beyond this exact linea dimerized phase evolving adiabatically from the exact state and extends over a wide region around this line.
