## Abstract We present a new twoβstep temporal discretization of the diffusion equation, which is formally secondβorderβaccurate and unconditionally stable. A novel aspect of the scheme is that it is monotonically damping: the damping rate is a monotonicallyβincreasing function of the diffusion coe
