چکیده
We present a comprehensive discussion of the ground-state properties dilute D-dimensional Bose gas interacting with few static impurities. Assuming short-ranged character boson-impurity interaction, we calculated energy three- and two-dimensional systems one two impurities immersed.

Weakly Interacting Bose Gas
We will look at the weakly interacting system at low temperatures. Already, without interactions, we have Bose condensation 〈 b+ 0 b0 〉 = N0 = N. (2) Interactions will reduce this, but if they are weak the depletion of the condensate will be a small fraction (N −N0)/N 1, or ∑ E k ′ 〈 bE k bE k 〉 N, (3) with ∑′ denoting the sum over all E k 6= 0. With the macroscopic occupation of the zero mode ...
متن کاملWeakly interacting Bose gas in a random environment
The localization-disorder paradigm is analyzed for a specific system of weakly repulsive Bose gas at zero temperature placed into a quenched random potential. We show that at low average density or weak enough interaction the particles fill deep potential wells of the random potential whose radius and depth depend on the characteristics of the random potential and the interacting gas. The local...
متن کاملCritical point of a weakly interacting two-dimensional Bose gas.
We study the Berezinskii-Kosterlitz-Thouless transition in a weakly interacting 2D quantum Bose gas using the concept of universality and numerical simulations of the classical absolute value psi(4) model on a lattice. The critical density and chemical potential are given by relations n(c) = (mT/2piPlanck's(2))ln(xiPlanck's(2)/mU) and mu(c) = (mTU/piPlanck's(2))ln(xi(mu)Planck's(2)/mU), where T...
متن کامل- Type Phase Transition for a Weakly Interacting Bose Gas
It is suggested a general mechanism through which a -type behavior is produced in the speci c heat of a Bose gas near the critical temperature Tc. It is essential that the quasiparticle spectra have a gap proportional to the condensate. It works for a general class of quasiparticle spectra, and in particular, for the weakly interacting Bose gas. The introduction of a chemical potential in the t...
متن کاملCritical temperature of a trapped, weakly interacting Bose gas.
We report on measurements of the critical temperature of a harmonically trapped, weakly interacting Bose gas as a function of atom number. Our results exclude ideal-gas behavior by more than two standard deviations, and agree quantitatively with mean-field theory. At our level of sensitivity, we find no additional shift due to critical fluctuations. In the course of this measurement, the onset ...
