Many-body formation and dissociation of a dipolar chain crystal

open access: yesNew Journal of Physics, 2014
We propose an experimental scheme to effectively assemble chains of dipolar gases with a uniform length in a multi-layer system. The obtained dipolar chains can form a chain crystal with the system temperature easily controlled by the initial lattice ...

Exact results on the two-particle Green's function of a Bose-Einstein condensate [PDF]

open access: yes, 2010
Starting from the Dyson-Beliaev and generalized Gross-Pitaevskii equations with an extra nonlocal potential, we derive an exact expression of the two-particle Green's function K for an interacting Bose-Einstein condensate in terms of unambiguously ...

SPT clusters with DES and HST weak lensing. II. Cosmological constraints from the abundance of massive halos [PDF]

open access: yesPhysical Review D
We present cosmological constraints from the abundance of galaxy clusters selected via the thermal Sunyaev-Zel'dovich (SZ) effect in South Pole Telescope (SPT) data with a simultaneous mass calibration using weak gravitational lensing data from the Dark ...

Few trapped quantum dipoles: quantum versus classical structures

open access: yesNew Journal of Physics, 2018
We analyze the ground state of a two-dimensional quantum system of a few strongly confined dipolar bosons. Dipoles arrange in different stable structures that depend on the tilting polarization angle and the anisotropy of the confining trap. To this end,

The 2018 GaN power electronics roadmap

open access: yesJournal of Physics D: Applied Physics, 2018
Gallium nitride (GaN) is a compound semiconductor that has tremendous potential to facilitate economic growth in a semiconductor industry that is silicon-based and currently faced with diminishing returns of performance versus cost of investment.

Predicting BNPL Loan Defaults: A Comparison of Ensemble Learning Models Combined With Balancing Techniques and an Analysis of the Impact of Digital Literacy

open access: yesEngineering Reports, Volume 8, Issue 2, February 2026.
In this study, we predicted BNPL loan defaults by introducing two new variables related to the use of digital banking platforms and assessing their impact. We compared ensemble learning models in combination with data balancing methods and logistic regression (for feature selection).

Collisional stability of localized Yb(3P2) atoms immersed in a Fermi sea of Li

open access: yesNew Journal of Physics, 2016
We establish an experimental method for a detailed investigation of inelastic collisional properties between ytterbium (Yb) in the metastable ${}^{3}{{\rm{P}}}_{2}$ state and ground state lithium (Li).

A Universal Energy Functional for Trapped Fermi Gases with Large Scattering Length

open access: yes, 2011
Yoram Alhassid conjectured that the total energy of a harmonically trapped two-component Fermi gas with large scattering length is a linear functional of the occupation probabilities of single-particle energy eigenstates.

The 2017 terahertz science and technology roadmap

open access: yesJournal of Physics D: Applied Physics, 2017
Science and technologies based on terahertz frequency electromagnetic radiation (100 GHz–30 THz) have developed rapidly over the last 30 years. For most of the 20th Century, terahertz radiation, then referred to as sub-millimeter wave or far-infrared ...
