Non ho accesso all'articolo:
Vitaly A. Kuzkin et al, Ballistic resonance and thermalization in the Fermi-Pasta-Ulam-Tsingou chain at finite temperature, Physical Review E (2020). DOI: 10.1103/PhysRevE.101.042209
e non sono sicuro di aver capito bene quanto si afferma nell'articolo:
<<Researchers from the Peter the Great St.Petersburg Polytechnic University (SPbPU) have discovered and theoretically explained a new physical effect: amplitude of mechanical vibrations can grow without external influence.>>
