In this article, we study the existence of ground state solutions for the Schrödinger-Poisson-Slater type equation with the Coulomb-Sobolev critical growth: −Δu+14π∣x∣∗∣u∣2u=∣u∣u+μ∣u∣p−2u,inR3,-\Delta u+\left(\frac{1}{4\pi | x| }\ast | u{| }^{2}\right)u=|

Ground-state Dirac monopole [PDF]
We show theoretically that a monopole defect, analogous to the Dirac magnetic monopole, may exist as the ground state of a dilute spin-1 Bose-Einstein condensate. The ground-state monopole is not attached to a single semi-infinite Dirac string, but forms a point where the circulation of a single vortex line is reversed.

Singular Mean-Field States: A Brief Review of Recent Results
This article provides a focused review of recent findings which demonstrate, in some cases quite counter-intuitively, the existence of bound states with a singularity of the density pattern at the center; the states are physically meaningful because ...

Entanglement energetics in the ground state [PDF]
We show how many-body ground state entanglement information may be extracted from sub-system energy measurements at zero temperature. A precise relation between entanglement and energy fluctuations is demonstrated in the weak coupling limit. Examples are given with the two-state system and the harmonic oscillator, and energy probability distributions ...

A Broadband Shared-Aperture L/S/X-Band Dual-Polarized Antenna for SAR Applications
This paper presents a novel tri-band antenna with dual polarizations and shared aperture. The proposed antenna operates at L-, S-, and X-bands with an approximate frequency ratio of 1:1.9:5.5.
