Abstract
We experimentally investigate the critical behavior of a phase transition between two topologically different turbulent states of electrohydrodynamic convection in nematic liquid crystals. The statistical properties of the observed spatiotemporal intermittency regimes are carefully determined, yielding a complete set of static critical exponents in full agreement with those defining the directed percolation class in (2+1) dimensions. This constitutes the first clear and comprehensive experimental evidence of an absorbing phase transition in this prominent non-equilibrium universality class.
