Injection and nucleation of topological defects in the quench dynamics of the Frenkel-Kontorova model
Oksana Chelpanova, Shane P. Kelly, Giovanna Morigi +2
Topological defects have strong impact on both elastic and inelastic properties of materials. In this article, we investigate the possibility to controllably inject topological def…
Noise-induced network topologies
Frederic Folz, Kurt Mehlhorn, Giovanna Morigi
We analyze transport on a graph with multiple constraints and where the weight of the edges connecting the nodes is a dynamical variable. The network dynamics results from the inte…
Interplay of periodic dynamics and noise: insights from a simple adaptive system
Frederic Folz, Kurt Mehlhorn, Giovanna Morigi
We study the dynamics of a simple adaptive system in the presence of noise and periodic damping. The system is composed by two paths connecting a source and a sink, the dynamics is…
From classical to quantum criticality
Daniel Podolsky, Efrat Shimshoni, Pietro Silvi +4
We study the crossover from classical to quantum phase transitions at zero temperature within the framework of theory. The classical transition at zero temperature can be des…
Full characterization of the quantum linear-zigzag transition in atomic chains
Pietro Silvi, Gabriele De Chiara, Tommaso Calarco +2
A string of repulsively interacting particles exhibits a phase transition to a zigzag structure, by reducing the transverse trap potential or the interparticle distance. The transi…
Quantum structural phase transition in chains of interacting atoms
Efrat Shimshoni, Giovanna Morigi, Shmuel Fishman
A quasi one--dimensional system of trapped, repulsively interacting atoms (e.g., an ion chain) exhibits a structural phase transition from a linear chain to a zigzag structure, tun…
