Exact results for one-dimensional disordered bosons with strong repulsion
A. De Martino, M. Thorwart, R. Egger +1
We study one-dimensional incommensurate bosons with strong repulsive interactions and weak disorder. In analogy to the clean Tonks-Girardeau gas, a Bose-Fermi mapping expresses thi…
Phase preparation by atom counting of Bose-Einstein condensates in mixed states
R. Graham, T. Wong, M. J. Collett +2
We study the build up of quantum coherence between two Bose-Einstein condensates which are initially in mixed states. We consider in detail the two cases where each condensate is i…
Collapses and Revivals of Collective Excitations in Trapped Bose Condensates
R. Graham, D. F. Walls, M. J. Collett +2
We present a quantum theory of low-lying excitations in a trapped Bose condensate with finite particle numbers. We find that even at zero temperature condensate number fluctuations…
Linear stochastic wave-equations for continuously measured quantum systems
Peter Goetsch, Robert Graham
While the linearity of the Schrödinger equation and the superposition principle are fundamental to quantum mechanics, so are the backaction of measurements and the resulting nonlin…
