With a Lagrangian quadratic in curvature we show that the Einstein-Hilbert action can be induced from a simple gauge model due to quantum corrections of torsion via formation of a gravito-magnetic condensate. An effective theory of cosmic knots at Planckian scale is proposed.6 pages, talk given at International Workshop "Supersymmetries and Quantum Symmetries", JINR, Dubna, Russia, July 27-31, 2005General Relativity and Quantum CosmologyLorentz Gauge Gravity and Induced Effective Theoriestext
