摘要: We study a discrete two-dimensional nonlinear system that allows for breather solutions. perform spectral analysis of the lattice dynamics at thermal equilibrium and use cooling technique to measure amount breathers equilibrium. Our results confirm existence an energy threshold breathers. The method provides novel way measuring analyzing distribution properties in
