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…
Quantum relaxation after a quench in systems with boundaries
Ferenc Iglói, Heiko Rieger
We study the time-dependence of the magnetization profile, m_l(t), of a large finite open quantum Ising chain after a quench. We observe a cyclic variation, in which starting with…
Finite-size effects in dynamics of zero-range processes
Janne Juntunen, Otto Pulkkinen, Juha Merikoski
The finite-size effects prominent in zero-range processes exhibiting a condensation transition are studied by using continuous-time Monte Carlo simulations. We observe that, well a…
Lattice-gas model for active vesicle transport by molecular motors with opposite polarities
Sudipto Muhuri, Ignacio Pagonabarraga
We introduce a multi-species lattice gas model for motor protein driven collective cargo transport on cellular filaments. We use this model to describe and analyze the collective m…
Quantum zigzag transition in ion chains
Efrat Shimshoni, Giovanna Morigi, Shmuel Fishman
A string of trapped ions at zero temperature exhibits a structural phase transition to a zigzag structure, tuned by reducing the transverse trap potential or the interparticle dist…
Phase transitions in cellular automata for cargo transport and kinetically constrained traffic
Marko Woelki
A probabilistic cellular automaton for cargo transport is presented that generalizes the totally asymmetric exclusion process with a defect from continuous time to parallel dynamic…
