We study possible scenarios for quantum non-demolition measurements using Bose-Einstein condensates. We show that the interactions between condensate atoms makes it possible to measure the atom number with minimal back action on the system. This is an example of atomic nonlinear optics that has significant implications in the quantum state preparation of the Bose condensates. Typeset using REVT...

We report on a systematic treatment of Coulomb corrections for 3-and n-particle (Bose-Einstein) correlations, leading to a removal of a 100 % systematic error from earlier Coulomb corrections of 5-particle Bose-Einstein correlations in heavy ion collisions. These results are generalized to include strong final state interactions and core-halo effects.

The role of geometrical frustration in strongly interacting bosonic systems is studied with a combined numerical and analytical approach. We demonstrate the existence of a novel quantum phase featuring both Bose-Einstein condensation and spin-glass behavior. The differences between such a phase and the otherwise insulating "Bose glasses" are elucidated.

The studies of Fermi–Dirac correlations of ΛΛ and ¯ Λ ¯ Λ pairs in hadronic Z decays, Bose–Einstein correlations and colour reconnection in W-pairs decays performed by the ALEPH collaboration in e + e − annihilation at LEP are presented. The OPAL analysis of Bose–Einstein correlations in W-pair decays is also discussed.

The coherent and collective nature of a Bose–Einstein condensate can enhance or suppress physical processes. Bosonic stimulation enhances scattering in already occupied states which leads to matter wave amplification, and the suppression of dissipation leads to superfluidity. In this article we present several experiments where enhancement and suppression have been observed and discuss the comm...

This is a lattice talk, but at first it won’t seem like it; it will be about atomic systems, and effective field theories. But studying the effective description of the atomic system will lead to a question suited to lattice techniques. I am summarizing 3 papers [1–3], all with Peter Arnold; the middle one contains all the lattice stuff. Many systems exhibit Bose condensation; for instance, liq...

– On the basis of a macroscopic ground state population it was argued recently that Bose-Einstein condensation should occur in a one-dimensional harmonic potential. We examine this situation by drawing analogies to Bosons in a two-dimensional box, where the thermodynamic limit is well-defined. We show that in both systems although the ground state populations show sharp onsets at the critical t...

We propose a new method to describe the interacting bose gas at zero temperature. For three-dimensional system the correction to the groundstate energy in density is reproduced. For two-dimensional dilute bose gas the groundstate energy in the leading order in the parameter | ln α2ρ|−1 where α is a scattering length is obtained.

Quantized vortices is a well-know signature of superfluidity. They have been studied extensively in superfluid Helium, type-II superconductors, Bose Einstein condensates and more recently in Fermi gas. We will discuss some mathematical analysis and numerical simulations of the quantized vortex nucleations in superconductors and Bose-Einstein condensates and discuss their connections and similar...
