Toda lattice formed in nonequilibrium steady states of SWCNT
Heeyuen Koh, Shigeo Maruyama
Toda lattice or FPUT chain-like dynamics have been regarded as the prerequisite condition to explain the length dependency of high thermal conductivity of low-dimensional systems a…
Strongly hybridized phonons in one-dimensional van der Waals crystals
Shaoqi Sun, Qingyun Lin, Yihuan Li +7
The phenomena of pronounced electron-electron and electron-phonon interactions in one-dimensional (1D) systems are ubiquitous, which are well described by frameworks of Luttinger l…
Bi-Hamiltonian in Semiflexible Polymers built upon Overdamping Process
Heeyuen Koh, Shigeo Maruyama
Quantifying the interaction between a system of interest and its ambient conditions, the memory effect links the states of two distinct Hamiltonians: one for the target system and…
Heat diffusion related damping process in highly precise coarse-grained model for SWCNT's nonlinearity
Heeyuen Koh, Chiashi Shohei, Junichiro Shiomi +1
Second sound and heat diffusion in single-walled carbon nanotubes (SWCNT) is well-known phenomena which is related to the high thermal conductivity of this material. In this paper,…
