Heat conductivity in the beta-FPU lattice. Solitons and breathers as energy carriers
T. Yu. Astakhova, V. N. Likhachev, G. A. Vinogradov
This paper consists of two parts. The first part proposes a new methodological framework within which the heat conductivity in 1D lattices can be studied. The total process of heat…

Vibrational resonances in 1D Morse and FPU lattices
T. Yu. Astakhova, N. S. Erikhman, V. N. Likhachev +1
In the present paper the resonances of vibrational modes in one-dimensional random Morse lattice are found and analyzed. The resonance energy exchange is observed at some values of…
