Strong correlation effects in 2D Bose-Einstein condensed dipolar excitons
2007 (English)In: Solid State Communications, ISSN 0038-1098, Vol. 144, no 9, 399-404 p.Article in journal (Refereed) Published
By doing quantum Monte Carlo ab initio simulations we show that dipolar excitons, which are now under experimental study, actually are strongly correlated systems. Strong correlations manifest in significant deviations of excitation spectra from the Bogoliubov one, large Bose condensate depletion, short-range order in the pair correlation function, and peak(s) in the structure factor. © 2007 Elsevier Ltd.
