Caldarelli, Guido and Maritan, Amos and Vendruscolo, Michele Hot sandpiles. EPL (Europhysics Letters), 35 (7). pp. 481-486. ISSN 0295-5075 (1996)Full text not available from this repository.
A temperature-like parameter is introduced in ordinary sandpiles models. A temperature-dependent probability distribution is assigned for the sand toppling on sites of any height. In mean-field theory criticality is obtained for all the values of temperature and no characteristic avalanche size appears. Numerical simulations support the existence of criticality at any temperature with apparently continuously varying critical exponents.
