A dynamical correspondence is established between positively curved, isotropic, perfect fluid cosmologies and quasi-two-dimensional, harmonically trapped Bose–Einstein condensates by mapping the equations of motion for both systems onto the one-dimensional Ermakov system. Parameters that characterize the physical properties of the condensate wavepacket, such as its width, momentum and energy, may be identified with the scale factor, Hubble expansion parameter and energy density of the universe…

A dynamic correspondence between Bose–Einstein condensates and Friedmann–Lemaître–Robertson–Walker and Bianchi I cosmology with a cosmological constant
In some interesting work of James Lidsey, the dynamics of Friedmann–Lemaitre–Robertson–Walker (FLRW) cosmology with positive curvature and a perfect fluid matter source is shown to be modeled in
Observer dependence for the phonon content of the sound field living on the effective curved space-time background of a Bose-Einstein condensate
We demonstrate that the ambiguity of the particle content for quantum fields in a generally curved space-time can be experimentally investigated in an ultracold gas of atoms forming a Bose-Einstein
Dynamical Invariants for Generalized Coherent States via Complex Quantum Hydrodynamics
For time dependent Hamiltonians like the parametric oscillator with time-dependent frequency, the energy is no longer a constant of motion. Nevertheless, in 1880, Ermakov found a dynamical invariant
Multi-fluid cosmology in Einstein gravity: analytical solutions
We review analytical solutions of the Einstein equations which are expressed in terms of elementary functions and describe Friedmann-Lemaître-Robertson-Walker universes sourced by multiple (real or
Analogue gravitational phenomena in Bose-Einstein condensates
Analogue gravity is based on the simple observation that perturbations propagating in several physical systems can be described by a quantum field theory in a curved spacetime. While phenomena like
Complex Nonlinear Riccati Equations as a Unifying Link in Fundamental Physics
Even if the discovery of the Higgs boson should be confirmed, the theoretical physics building is far from being complete. Essential everyday experience like dissipation and irreversibility are not
Vortex analogue for the equatorial geometry of the Kerr black hole
The spacetime geometry on the equatorial slice through a Kerr black hole is formally equivalent to the geometry felt by phonons entrained in a rotating fluid vortex. We analyse this example of


Anisotropic Bose-Einstein condensates and completely integrable dynamical systems
A Gaussian ansatz, for the wave function of two-dimensional harmonically trapped anisotropic Bose-Einstein condensates is shown to lead, via a variational procedure, to a coupled system of two
Sonic analog of gravitational black holes in bose-einstein condensates
It is shown that, in dilute-gas Bose-Einstein condensates, there exist both dynamically stable and unstable configurations which, in the hydrodynamic limit, exhibit a behavior resembling that of

Analytical results for the macroscopic wave function of a Bose-Einstein condensate in a time dependent harmonic potential are presented, characterized by three scaling factors which allow a classical interpretation of the dynamics.
Theory of Bose-Einstein condensation in trapped gases
The phenomenon of Bose-Einstein condensation of dilute gases in traps is reviewed from a theoretical perspective. Mean-field theory provides a framework to understand the main features of the
Chaotic inflation from a scalar field in nonclassical states
We study chaotic inflation driven by a real, massive, homogeneous minimally coupled scalar field in a flat Robertson-Walker spacetime. The semiclassical limit for gravity is considered, whereas the
Conformal symmetry and the nonlinear Schrödinger equation
We show that the width of the wave packet of a class of generalized nonlinear Schr\"odinger equations (NLSE) trapped in an arbitrary time-dependent harmonic well in any dimensions is universally

We present a numerical study of the time-dependent and time-independent Gross-Pitaevskii (GP) equation in two space dimensions, which describes the Bose-Einstein condensate of trapped bosons at
Stable 85Rb bose-einstein condensates with widely tunable interactions
Bose-Einstein condensation has been achieved in a magnetically trapped sample of 85Rb atoms. Long-lived condensates of up to 10(4) atoms have been produced by using a magnetic-field-induced Feshbach
