Thermal rectification in segmented Frenkel-Kontorova lattices with asymmetric next-nearest-neighbor interactions
M. Romero-Bastida, A. Poceros Varela
In this work we conduct an extensive study of the asymmetric heat flow, i.e. thermal rectification, present in the two-segment Frenkel Kontorova model with both nearest-neighbor (N…
Effect of external potential on the energy transport in harmonically driven segmented Frenkel-Kontorova lattices
M. Romero-Bastida
Thermal resonance, that is, the heat flux obtained by means of a periodic external driving, offers the possibility of controlling heat flux in nanoscale devices suitable for power…
Thermal rectification in mass-asymmetric one-dimensional anharmonic oscillator lattices with and without a ballistic spacer
M Romero-Bastida, Brandon Armando Martínez-Torres
In this work we perform a systematic analysis of various structural parameters that have influence on the thermal rectification effect, i.e. asymmetrical heat flow, and the negativ…
Size effects on thermal rectification in mass-graded anharmonic lattices
M. Romero-Bastida, Armando Gonzalez-Alarcon
In this work we study the thermal rectification efficiency of a one-dimensional mass-graded anharmonic oscillator lattice at large system sizes. A modest increase in rectification…
Covariant hydrodynamic Lyapunov modes and strong stochasticity threshold in Hamiltonian lattices
M. Romero-Bastida, Diego Pazó, Juan M. López
We scrutinize the reliability of covariant and Gram-Schmidt Lyapunov vectors for capturing hydrodynamic Lyapunov modes (HLMs) in one-dimensional Hamiltonian lattices. We show that,…
Structure of characteristic Lyapunov vectors in anharmonic Hamiltonian lattices
M. Romero-Bastida, Diego Pazó, Juan M. López +1
In this work we perform a detailed study of the scaling properties of Lyapunov vectors (LVs) for two different one-dimensional Hamiltonian lattices: the Fermi-Pasta-Ulam and …
