Superfluid to Bose-Glass transition in a 1D weakly interacting Bose gas.
We study the one-dimensional Bose gas in spatially correlated disorder at zero temperature, using an extended density-phase Bogoliubov method. We analyze, in particular, the decay of the one-body density matrix and the behavior of the Bogoliubov excitations across the phase boundary. We observe that the transition to the Bose-glass phase is marked by a power-law divergence of the density of sta...
متن کاملQuasiparticle spectrum for the dilute Bose-gas in an inhomogeneous external field
The paper deals with the properties of Bose-gases in the inhomogeneous external fields at very low temperatures, when a Bose-Einstein condensation occurs. This particularly refers to the trapped alkali gases, which are of great experimental and theoretical interest during last few years. The system is considered here in the frame of the developed approach closed to the Bogoliubov’s one with nec...
متن کاملExperimental observation of the Bogoliubov transformation for a Bose-Einstein condensed gas
The pioneering paper by Bogoliubov in 1947 was the starting point for a microscopic theory of superfluidity [1]. Bogoliubov found the non-perturbative solution for a weakly interacting gas of bosons. The main step in the diagonalization of the Hamiltonian is the famous Bogoliubov transformation, which expresses the elementary excitations (or quasiparticles) with momentum q in terms of the free ...
متن کاملThree-wave mixing of bogoliubov quasiparticles in a bose-einstein condensate.
A dressed basis is used to calculate the dynamics of three-wave mixing between Bogoliubov quasiparticles in a Bose condensate. Because of the observed oscillations between different momentum modes, an energy splitting, analogous to the optical Mollow triplet, appears in the Beliaev damping spectrum of the excitations from the oscillating modes.
متن کاملAnderson localization of Bogolyubov quasiparticles in interacting Bose-Einstein condensates.
We study the Anderson localization of Bogolyubov quasiparticles in an interacting Bose-Einstein condensate (with a healing [corrected] length xi) subjected to a random potential (with a finite correlation length sigma(R)). We derive analytically the Lyapunov exponent as a function of the quasiparticle momentum k, and we study the localization maximum k(max). For 1D speckle potentials, we find t...
