Perhaps the most useful analytic tool in gauge theory is the Uhlenbeck compactness theoremfor sequences of unitary connections on hermitian vector bundles [U]. Given connections {Dj} ona bundle E over...
We develop an efficient iterative water-filling algorithm to find an optimal transmit spectrum for maximum sum capacity in a Gaussian multiple access channel with vector inputs and a vector output. Th...
We perform a calculation of the isospin and hypercharge vector-current propagators (ΔV33μν(q2) and ΔV88μν(q2)) to two loops in chiral perturbation theory. The analysis is carried out with straight-for...
We perform a calculation of the isospin and hypercharge axial vector current propagators [ΔA3μν(q) and ΔA8μν(q)] to two loops in SU(3)×SU(3) chiral perturbation theory. A large number of O(p6) diverge...
We calculate chiral corrections to the semileptonic vector and axial quark coupling constants using a manifestly Lorentz covariant chiral quark approach up to order O(p4) in the two- and three-flavor ...
The propagation and focusing properties of partially coherent vector beams including radially polarized and azi-muthally polarized (AP) beams are theoretically and experimentally investigated. The bea...
In this paper, an explicit formulation for two dimensional multi- variate truncated power functions is presented, and a simpli痚d explicit for- mulation for two dimensional vector partition functions...
Several advances have extended the power and versatility of coherent state theory to the extent that it has become a vital tool in the representation theory of Lie groups and their Lie algebras. Repre...
A super-length optical needle (~14λ) of strong transversally polarized field with homogeneous intensity along the optical axis and subdiffraction beam size ( ~0 .9λ) can be generated by focusing a hyb...
A technique using vector Slepian harmonics and multipole fields is presented for a general treatment of the inverse problem of high numerical aperture focusing. A prescribed intensity distribution or ...
We construct and discuss a semi-rational, multi-parametric vector solution of coupled nonlinear Schr\"odinger equations (Manakov system). This family of solutions includes known vector Peregrine solut...
This work addresses the study of two-dimensional electron gas in a perpendicular magnetic field in the presence of both Rashba and Dresselhaus spin-orbit (SO) interactions, with effective Zeeman coupl...

We theoretically investigate the tight focusing properties of hybridly polarized vector beams. Some numerical results are obtained to illustrate the intensity, phase, and polarization of tightly focus...
This letter demonstrates the feasibility of a novel direct detection microwave photonic vector modulation scheme for the radio-over-fiber (RoF) system. Unlike the traditional double-sideband with opti...
