Interface thermal resistance between dissimilar anharmonic lattice
Baowen Li, Jing-Hua Lan, Lei Wang
We study interface thermal resistance (ITR) in a system consisting of two dissimilar anharmonic lattices exemplified by Fermi-Pasta-Ulam (FPU) model and Frenkel-Kontorova (FK) mode…

Fidelity of a Bose-Einstein Condensate
Jie Liu, Wenge Wang, Chuanwei Zhang +2
We investigate fidelity, the Loschmidt echo, for a Bose-Einstein Condensate. It is found that the fidelity decays with time in various ways (exponential, Gaussian, and power-law),…
