. After quite some time, I was able to publish a single-author work again. My paper on a sandpile-based model of earthquakes was accepted in EPL (Europhysics Letters) . R.C. Batac, Clustering regimes in a sandpile with targeted triggering, EPL ( Europhysics Letters ) 135 , 19003, DOI:10.1209/0295-5075/135/19003 (2021). This work is an extension of an idea that came to me during one of the discussions with my principal investigator during my postdoc work. Prof. Dr. Holger Kantz, himself an early researcher on discrete models of self-organized criticality (SOC), noted that the sandpile model, while exhibiting SOC, in fundamentally different from earthquakes, which are perhaps the most famous large-scale examples of SOC. Whereas earthquakes dissipate energy is bursts of correlated activity, the sandpile generates single-shot avalanches. When energy is depleted in a sandpile grid, it has to wait again before a new significant event can be generated. Because of this, for t...
