Superposition states of ultracold bosons in rotating rings with a weak potential barrier
Superposition states ultracold bosons weak potential barrier
2010/11/23
We study ultracold bosons in a one-dimensional rotating ring lattice with a weak potential barrier well below unit filling. Due to the potential barrier the eigenstates are superpositions of different...
Effect of weak magnetic field on quantum spin correlation in an s-wave superconductor
Effect of weak magnetic field quantum spin correlation
2010/11/22
We study the effect of a weak magnetic field on the state of the spins of a pair of electrons forming a Cooper pair in an s-wave superconductor. By perturbatively solving time-dependent Bogoliubov equ...
Experimental evidence of ageing and slow restoration of the weak-contact configuration in tilted 3D granular packings
Granular solids Nonlinear acoustic probing Avalanches

Granular packings slowly driven towards their instability threshold are studied using a digital imaging technique as well as a nonlinear acoustic method. The former method allows us to study grain rea...
