Soliton-Like Pulses in Vertical Granular Chain Under Gravity: Particle-Like or Wave-Like?
We numerically study the propagation, reflection and collision of soliton-like pulses in the vertical granular chain under gravity. For the pure granular chain system, during the propagation and
Power-Law in Depth-Dependence of Signal Speed in Vertical Granular Chain*
The signal generated by an initial perturbation dispersively propagates in the vertical granular chain under gravity. For the power-law-type contact force, the signal speed follows power-law with the
Persistent Current in Two Connected Mesoscopic Rings with Reservoirs
The persistent current and transmission of two connected Aharonov–Bohm rings coupled to external leads are solved analytically. The conditions on which we may observe persistent current, zero or
