Mean-field spin glass models are known to have a rather complex
low-temperature phase, which has not been clearly observed so far in
numerical simulations of finite-dimensional models with short range
interactions.
One-dimensional spin glass models with power law decaying
interactions allow to explore both regimes (long and short-range) by
changing the exponent of the power law.
Moreover a map can be set between the exponent value and the effective
dimension of an equivalent short range interacting model.
Nonetheless numerical simulations of this kind of models, where each
variable interacts with all the others, are very computer demanding when
increasing the system size and do not lead to any clear numerical
evidence supporting a specific spin glass theory over the others.
We introduce a diluted version of this model, where each variable
interacts only with a finite number of others and the probability of
having a link decreases as a power law with the distance of the
interacting spins.
The computing effort is thus substantially reduced, allowing us to
simulate larger sizes for longer times.
We present both the static and dynamic analysis of this model.
