Strong Disorder Fixed Point in Absorbing-State Phase Transitions
Strong Disorder Fixed Point in Absorbing-State Phase Transitions is a scholarly work, published in 2003 in ''Physical Review Letters''. The main subjects of the publication include critical phenomena, phase change, condensed matter physics, many-body problem, Universality, physics, mathematical physics, fixed point, critical exponent, renormalization group, Percolation, Infrared fixed point, critical point, statistical physics, non-equilibrium thermodynamics, directed percolation, interacting particle system, and critical dimension. The authors show that for sufficiently strong disorder the critical behavior is controlled by a strong disorder fixed point and in one dimension the critical exponents are conjectured to be exact: beta=(3-sqrt5)/2 and nu( perpendicular )=2.
