Hankel Operators on Fock Spaces [PDF]

open access: yes, 2013
We study Hankel operators on the weighted Fock spaces\ud Fp. The boundedness and compactness of these operators are characterized in terms of BMO and VMO, respectively. Along the way, we also study Berezin transform and harmonic conjugates on the plane.

Quenching the Hubbard Model: Comparison of Nonequilibrium Green's Function Methods

open access: yesContributions to Plasma Physics, EarlyView.
ABSTRACT We benchmark nonequilibrium Green's function (NEGF) approaches for interaction quenches in the half‐filled Fermi–Hubbard model in one and two dimensions. We compare fully self‐consistent two‐time Kadanoff–Baym equations (KBE), the generalized Kadanoff–Baym ansatz (GKBA), and the recently developed NEGF‐based quantum fluctuations approach (NEGF‐

Investigating the Nuclear Structure of 65Cu using the Shell Model and Hartree-Fock+BCS Approach

open access: yesIraqi Journal of Physics
This research studied the nuclear deformation of the 65Cu isotope by employing advanced shell model calculations alongside the Hartree-Fock approximation within the framework of the fp-shell model space.

The Virial Expansion of the Hydrogen Equation of State in Comparison to PIMC Simulations: The Quasiparticle Concept, IPD, and Ionization Degree

open access: yesContributions to Plasma Physics, EarlyView.
ABSTRACT The properties of plasmas in the low‐density limit are described by virial expansions. Analytical expressions are known for the lowest virial coefficients from Green's function approaches. Recently, accurate path‐integral Monte Carlo (PIMC) simulations were performed for the hydrogen plasma at low densities by Filinov and Bonitz (Phys. Rev.

How (not) to Cage an Electron: The Perfluoro Cage Effect as an Extrinsic Molecular Property

open access: yesHelvetica Chimica Acta, EarlyView.
A rigorous definition within Kohn–Sham density functional theory is presented for the notion of an caged electron inside perfluorinated fullerenes as radical anions. ABSTRACT The notion of a (molecular) electron cage was coined for the unique hosting capacity of perfluorocubane, suggesting the “encapsulation of an electron” within the highly symmetric ...

Gluon skewed generalized parton distributions of proton from a light-front Hamiltonian approach

open access: yesPhysics Letters B
We calculate all leading-twist gluon generalized parton distributions (GPDs) inside the proton at nonzero skewness using the basis light-front quantization framework.

Sending-or-not-sending twin-field quantum key distribution with redundant space

open access: yesPhysical Review Research, 2023
We propose to adopt redundant space such as polarization mode in the sending-or-not-sending twin-field quantum key distribution (TF-QKD) in the Fock space.

Factorization and reflexivity on Fock spaces [PDF]

open access: yesIntegral Equations and Operator Theory, 1995
The framework of the paper is that of the full Fock space ${\Cal F}^2({\Cal H}_n)$ and the Banach algebra $F^\infty$ which can be viewed as non-commutative analogues of the Hardy spaces $H^2$ and $H^\infty$ respectively. An inner-outer factorization for any element in ${\Cal F}^2({\Cal H}_n)$ as well as characterization of invertible elements in $F ...

Eliminating disorderly A sites: Significantly enhanced external quantum efficiency of Bi3+ luminescence in double perovskite phosphor

open access: yesInfoMat, EarlyView.
The structural transformation from disorder to order was achieved by regulating the A‐site of double perovskite, boosting IQE and EQE to 78% and 43%, respectively. The excellent luminescence properties of the representative CYNO:1%Bi3+ phosphor highlight the multifunctional application potential in solid‐state lighting, fingerprint recognition, and ...

The Fock Space in the Slice Hyperholomorphic Setting [PDF]

open access: yes, 2014
In this paper we introduce and study some basic properties of the Fock space (also known as Segal–Bargmann space) in the slice hyperholomorphic setting. We discuss both the case of slice regular functions over quaternions and the case of slice monogenic ...
