Kovacs Memory Effect in a Thin Granular Layer: Experimental Evidence and Its Physical Origin
feeds.aps.org · By Francisco Vega Reyes, Álvaro Rodríguez-Rivas, Pablo Maynar & M. Isabel García de Soria ·
The Brief
- The anomalous Kovacs memory effect has been experimentally observed in a granular system for the first time.
- The study is reported in Physical Review Letters, volume 137, article 208201, by Francisco Vega Reyes, Álvaro Rodríguez-Rivas, Pablo Maynar and M. Isabel García de Soria.
- The paper presents experimental evidence and an analysis of the physical origin of the effect in a thin granular layer.
Why it matters
It extends a memory effect previously studied in other systems to granular matter, giving physicists an experimental case for testing theories of non-equilibrium behaviour.
Who’s affected
- physicists studying granular matter and non-equilibrium systems
