Extremal functions and best approximate formulas for the Hankel-type Fock space

Cubo
In this paper we recall some properties for the Hankel-type Fock space \(\mathscr{F}_{\alpha,\ast}(\mathbb{C}^d)\). This space was introduced by Cholewinsky in 1984 and plays a background to our contribution. Especially, we examine the extremal functions

Universal Verma Modules and the Misra-Miwa Fock Space

International Journal of Mathematics and Mathematical Sciences, 2010
The Misra-Miwa v-deformed Fock space is a representation of the quantized affine algebra Uv(sl^ℓ). It has a standard basis indexed by partitions, and the nonzero matrix entries of the action of the Chevalley generators with respect to this basis are ...

The Hilbert space of large N Chern-Simons matter theories

Journal of High Energy Physics, 2022
We demonstrate that the known expressions for the thermal partition function of large N Chern-Simons matter theories admit a simple Hilbert space interpretation as the partition function of an associated ungauged large N matter theory with one additional

Efficient Heat-Bath Sampling in Fock Space. [PDF]

Journal of Chemical Theory and Computation, 2015
We introduce an algorithm for sampling many-body quantum states in Fock space. The algorithm efficiently samples states with probability approximately proportional to an arbitrary function of the second-quantized Hamiltonian matrix element connecting the

Products of Hankel operators on the Fock space

Journal of Functional Analysis, 2019
For entire functions f and g we study the problem of when the Hankel product H f ‾ ⁎ H g ‾ is bounded or compact on the Fock space F α 2 . This is a companion to Sarason's Toeplitz product problem which was completely solved for the Fock space by Cho ...

Inducing Ferromagnetism by Structural Engineering in a Strongly Spin‐Orbit Coupled Oxide

Advanced Functional Materials, EarlyView.
ABSTRACT Magnetic materials with strong spin‐orbit coupling (SOC) are essential for the advancement of spin‐orbitronic devices, as they enable efficient spin‐charge conversion, complex magnetic structures, spin‐valley physics, topological phases and other exotic phenomena.

Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics

Advanced Materials, EarlyView.
The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and

A Quest for the Mechanism of Ultrahigh Resolution SEM Imaging

Advanced Science, EarlyView.
Using Monte Carlo simulations with explicit definitions of SE1 and SE2 align with a cascade secondary electron production model, this work shows that the 3D nanostructure modulated SE2 emission enhances other than to reduce topographical contrast via a “miniature Faraday cup” effect.

Toeplitz Operators on Fock Space over ${\mathbb{C}}^{\mathit{n}}$ with Invariant Symbols under the Action of the Unit Circle

Axioms, 2023
The first goal of this paper is to find a representation of the Fock space on Cn in terms of the weighted Bergman spaces of the projective spaces CPn−1; i.e., every function in the Fock space can be written as a direct sum of elements in weighted Bergman
