Critical slowing down and hyperuniformity on approach to jamming.
Hyperuniformity characterizes a state of matter that is poised at a critical point at which density or volume-fraction fluctuations are anomalously suppressed at infinite wavelengths. Recently, much attention has been given to the link between strict jamming (mechanical rigidity) and (effective or exact) hyperuniformity in frictionless hard-particle packings. However, in doing so, one must nece...
متن کاملSlow Relaxation due to Entropy Effect – Entropic Slowing Down –
We study entropic slowing down in a decorated bond system. Though it is commonly known that complicate energy landscape in random spin systems causes slow relaxations, we find that the slowing down also appears due to an entropic effect even if the energy barrier between the stable and the metastable states is very small. The concept of the entropic slowing down is proposed by using a decorated...
متن کاملCritical Slowing Down Governs the Transition to Neuron Spiking
Many complex systems have been found to exhibit critical transitions, or so-called tipping points, which are sudden changes to a qualitatively different system state. These changes can profoundly impact the functioning of a system ranging from controlled state switching to a catastrophic break-down; signals that predict critical transitions are therefore highly desirable. To this end, research ...
متن کاملSlowing down pension indexing: the foreign experience.
Between 1975 and 1983, Canada, Finland, Sweden, the United Kingdom, and the Federal Republic of Germany--countries faced with immediate or long-term financing difficulties in their social security systems--modified their social security pension adjustment procedures. These changes in pension adjustments very often were made in conjunction with other restrictive measures such as increased contri...
متن کاملCritical slowing down in polynomial time algorithms.
Combinatorial optimization algorithms that compute exact ground states for disordered magnets are seen to exhibit critical slowing down at zero temperature phase transitions. Using the physical features of the models, such as vanishing stiffness on one side of the transition and the ground state degeneracy, the number of operations needed in the push-relabel algorithm for the random field Ising...
