Effects of weak disorder on the thermalization of Fermi–Pasta–Ulam–Tsingou model

Effects of weak disorder on the thermalization of Fermi–Pasta–Ulam–Tsingou model

We study the effects of two kinds of weak disorders on the thermalization of the Fermi–Pasta–Ulam–Tsingou model by extensive numerical simulations. The disorders are introduced to the mass of atom or coefficient of the quadratic term of potential energy. The initial energy is distributed equally amo...
