Effect of discrete breathers on macroscopic properties of the Fermi-Pasta-Ulam chain
Elena A. Korznikova, Alina Y. Morkina, Mohit Singh +5
The effect of discrete breathers (DBs) on macroscopic properties of the Fermi-Pasta-Ulam chain with symmetric and asymmetric potentials is investigated. The total to kinetic energy…

Effect of discrete breathers on the specific heat of a nonlinear chain
Mohit Singh, Alina Y. Morkina, Elena A. Korznikova +6
A nonlinear chain with six-order polynomial on-site potential is used to analyze the evolution of the total to kinetic energy ratio during development of modulational instability o…
