Surface-atom force out of thermal equilibrium and its effect on ultra-cold atoms
نویسنده
چکیده
The surface-atom Casimir-Polder-Lifshitz force out of thermal equilibrium is investigated in the framework of macroscopic electrodynamics. Particular attention is devoted to its large distance limit that shows a new, stronger behaviour with respect to the equilibrium case. The frequency shift produced by the surface-atom force on the the center-of-mass oscillations of a harmonically trapped Bose-Einstein condensate and on the Bloch oscillations of an ultra-cold fermionic gas in an optical lattice are discussed for configurations out of thermal equilibrium.

Interfacing cold atoms and nanostructures
Trapping and manipulating atoms by means of microscopic traps has seen enormous advances within the last decade. Today, ultra-cold atom clouds, Bose-Einstein condensates, and Fermi gases are routinely trapped in conservative potential at the surface of microchips. Such experiments have delivered important insights into fundamental interactions between atoms and surfaces and pave the way towards...
متن کاملMolecular Dynamics Simulation of Al Energetic Nano Cluster Impact (ECI) onto the Surface
On the atomic scale, Molecular Dynamic (MD) Simulation of Nano Al cluster impact on Al (100) substrate surface has been carried out for energies of 1-20 eV/atom to understand quantitatively the interaction mechanisms between the cluster atoms and the substrate atoms. The many body Embedded Atom Method (EAM) was used in this simulation. We investigated the maximum substrate temperature Tmax and...
متن کاملThermally Induced Losses in Ultra-Cold Atoms Magnetically Trapped Near Room-Temperature Surfaces
We have measured magnetic trap lifetimes of ultra-cold Rb atoms at distances of 5-1000 μm from surfaces of conducting metals with varying resistivity. Good agreement is found with a theoretical model for losses arising from near-field magnetic thermal noise, confirming the complications associated with holding trapped atoms close to conducting surfaces. A dielectric surface (silicon) was found ...

Graphene is a monolayer carbon atoms discovered in the recent past which has inspired researchers in a wide range of applications. It has a surface area as high as 2630 m2/g and thermal conductivity value of 3000 W/mK-1 at room temperature. It is chemically the most reactive form of carbon with one carbon atom exposed to reaction from each side. Stable dispersion of graphene was achieved using ...
