Quantum gas mixtures in different correlation regimes
We present a many-body description for two-component ultracold bosonic gases
when one of the species is in the weakly interacting regime and the other is
either weakly or strongly interacting. In the one-dimensional limit the latter
case system is a hybrid in which a Tonks-Girardeau gas is immersed in a
Bose-Einstein condensate, which is an example of a new class of quantum system
involving a tunable, superfluid environment. We describe the process of phase
separation microscopically and semiclassically in both situations and show that
the quantum correlations are maintained in the separated phase.Comment: 4 pages, 3 figure
The initial public offering of high-technology firms: female executive managers and innovation
This study addresses how gender diversity in management teams influences the success of the IPO of research-intensive firms, and how critical indicators of innovation capabilities for those types of firms can mediate the gender effect
Single-atom control of the optoelectronic response in sub-nanometric cavities
By means of ab-initio time dependent density functional theory calculations
carried out on an prototypical hybrid plasmonic device (two metallic
nanoparticles bridged by a one-atom junction), we demonstrate the strong
interplay between photoinduced excitation of localized surface plasmons and
electron transport through the single atom. Such an interplay is remarkably
sensitive to the atomic orbitals of the junction. Therefore, we show the
possibility of a twofold tuning (plasmonic response and photoinduced current
across the juntion) just by changing a single atom in the device.Comment: 5 pages, 5 figure
