In this paper we study the corrections emergent from a Ho\v{r}ava-Lifshitz extension of complex scalar sector to Bose-Einstein condensation and thermodynamics parameters. We initially discussed some features model only then compute condensation. The calculations were done by computing generating functional, which extract also obtained Lifshitz scaling correction for critical temperature $T_c$ t...

1. Introduction The zero-range process (ZRP) [1] is a simple lattice-based model for driven diffusive systems. For certain choices of parameters, the model exhibits a condensation transition (analogous to Bose-Einstein condensation) where a macroscopic proportion of particles accumulate on a single site [2]. Condensation is well-known in colloidal and granular systems [3] and also occurs in a v...

Systems driven out of equilibrium can often exhibit behaviour not seen in systems in thermal equilibriumfor example phase transitions in one-dimensional systems. In this talk I will review several ‘condensation’ transitions that occur when a conserved quantity is driven through the system. Although the condensation is spatial, i.e. a finite fraction of the conserved quantity condenses into a sm...

We present neutron scattering measurements of the atomic momentum distribution n(k) in solid helium under a pressure p=41 bar (molar volume Vm=20.01+/-0.02 cm3/mol) and at temperatures between 80 and 500 mK. The aim is to determine whether there is Bose-Einstein condensation (BEC) below the critical temperature, Tc=200 mK, where a superfluid density has been observed. Assuming BEC appears as a ...

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 theoretical description of trapped weakly-interacting Bose-Einstein condensates is characterized by a large number of seemingly very different approaches which have been developed over the course of time by researchers with very distinct backgrounds. Newcomers to this field, experimentalists and young researchers all face a considerable challenge in navigating through the ‘maze’ of abundant...

Bose-Einstein condensation (BEC) in two dimensions (2D) (e.g., to describe the quasi-2D cuprates) is suggested as the possible mechanism widely believed to underlie superconductivity in general. A crucial role is played by nonzero center-of-mass momentum Cooper pairs (CPs) usually neglected in BCS theory. Also vital is the unique linear dispersion relation appropriate to weakly-coupled “bosonic...

We have observed a Bose-Einstein condensate in a dilute gas of 4He in the (3)2S(1) metastable state. We find a critical temperature of (4.7+/-0.5) microK and a typical number of atoms at the threshold of 8 x 10(6). The maximum number of atoms in our condensate is about 5 x 10(5). An approximate value for the scattering length a = (16+/-8) nm is measured. The mean elastic collision rate at thres...

Date The final copy of this thesis has been examined by the signatories, and we find that both the content and the form meet acceptable presentation standards of scholarly work in the above mentioned discipline. Thesis directed by Prof. Eric Cornell Bose-Einstein condensates in dilute atomic gases have been around for almost 5 years now. The first experiments dealt with density related properti...
