Experimental study of a noisy dissipative-driven ring lattice with Morse interactions

摘要

An experimental study has been carried out of a noisy dissipative-driven ring lattice of units coupled via Morse potentials. An electronic circuit mimicking the lattice dynamics and noise sources is used. We show that inclusion of long range attractive forces facilitates clustering (at variance with the repulsive Toda ring) and van der Waals-like transition phenomena.
