Rupture and healing of one-dimensional chains in a parametric magnetic ratchet potential.
نویسندگان
چکیده
Transverse paramagnetic particle chains parametrically driven by a magnetic ratchet potential rupture and heal upon collision with an obstacle. The overdamped transverse dynamics is frozen during the time the particles stay in the ratchet potential wells and kicked during the time the particles hop to the next well. On time scales large compared to the parametric modulation period the healing of the hole in the chain is determined by dipolar repulsion and hydrodynamic friction of the paramagnetic particles.

A Parametric Study on the Progressive Collapse Potential of Steel Buildings under Truck Collision
In this paper, the initiation and propagation of structural damage in a building due to the truck collision to one of its corner columns were investigated. For this purpose, a three-dimensional 4-story moment resisting steel frame with intermediate ductility was considered. The structure was designed using ETABS software under standard dead, live, and earthquake loads, and then impact loading w...
متن کاملSimultaneous Decentralized Competitive Supply Chain Network Design under Oligopoly Competition
This paper discusses a problem in which decentralized supply chains enter the market simultaneously with no existing rival chains, shape the supply chains’ networks, and set wholesale and retail prices in a noncooperative manner. All the chains produce either identical or highly substitutable products. Customer demand is elastic and price-dependent. A three-step algorithm is proposed to solve ...
متن کاملCalculation of Quasi-one-dimensional Interacting Electron Gas Using the Hartree-Fock Method
In this paper, the Hartree-Fock method has been formulated to investigate some of the ground state properties of quasi-one-dimensional interacting electron gas in the presence of the magnetic field. The bare coulomb interaction between electrons has been assumed. For this system, we have also computed some of its thermodynamic and magnetic properties such as the energy, pressure, incompressibil...
متن کاملInterplay between quantum dissipation and an in-plane magnetic field in the spin ratchet effect
We investigate the existence of the pure spin ratchet effect in a dissipative quasi-one-dimensional system with Rashba spin-orbit interaction. The system is additionally placed into a transverse uniform stationary in-plane magnetic field. It is shown that the effect exists at low temperatures and pure spin currents can be generated by applying an unbiased ac driving to the system. An analytical...
