Squeezing and entanglement in a Bose-Einstein condensate
J. Esteve, C. Gross, A. Weller +2
Entanglement, a key feature of quantum mechanics, is a resource that allows the improvement of precision measurements beyond the conventional bound reachable by classical means. Th…
Formation Of A Cold Antihydrogen Beam in AEGIS For Gravity Measurements
G. Testera, A. S. Belov, G. Bonomi +62
The formation of the antihydrogen beam in the AEGIS experiment through the use of inhomogeneous electric fields is discussed and simulation results including the geometry of the ap…
Single Particle Tunneling in Strongly Driven Double Well Potentials
E. Kierig, U. Schnorrberger, A. Schietinger +2
We report on the first direct observation of coherent control of single particle tunneling in a strongly driven double well potential. In our setup atoms propagate in a periodic ar…
Experimental observation of oscillating and interacting matter wave dark solitons
A. Weller, J. P. Ronzheimer, C. Gross +5
We report on the generation, subsequent oscillation and interaction of a pair of matter wave dark solitons. These are created by releasing a Bose-Einstein condensate from a double…
Spontaneous symmetry breaking of gap solitons in double-well traps
M. Trippenbach, E. Infeld, J. Gocalek +3
We introduce a two dimensional model for the Bose-Einstein condensate with both attractive and repulsive nonlinearities. We assume a combination of a double well potential in one d…
