Toeplitz Operators with Horizontal Symbols Acting on the Poly-Fock Spaces
Journal of Function Spaces, 2018 We describe the C⁎-algebra generated by the Toeplitz operators acting on each poly-Fock space of the complex plane C with the Gaussian measure, where the symbols are bounded functions depending only on x=Re z and have limit values at y=-∞ and y=∞. The C⁎

Factorization and reflexivity on Fock spaces [PDF]
Integral 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 ...

Laser‐assisted in situ fabrication of atomically thin Ga2O3 films for dielectric applications
FlexMat, EarlyView.A confinement template‐assisted squeeze method, in conjunction with laser‐assisted in situ oxidation, facilitates fabrication of centimeter‐scale and atomically thin gallium oxide films from liquid gallium under room temperature conditions. This low‐damage approach avoids thermal degradation of sensitive materials and supports high‐performance field ...

Generalized Fock space and contextuality
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2019 This paper is devoted to linear space representations of contextual probabilities—in generalized Fock space. This gives the possibility to use the calculus of creation and annihilation operators to express probabilistic dynamics in the Fock space (in particular, the wide class of classical kinetic equations).

InfoMat, 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 ...

Hartree–Fock many-body perturbation theory for nuclear ground-states
Physics Letters B, 2016 We investigate the order-by-order convergence behavior of many-body perturbation theory (MBPT) as a simple and efficient tool to approximate the ground-state energy of closed-shell nuclei.

From deformed Hartree-Fock to the nucleon-pair approximation
Physics Letters B, 2020 The nucleon-pair approximation (NPA) can be a compact alternative to full configuration-interaction (FCI) diagonalization in nuclear shell-model spaces, but selecting good pairs is a long-standing problem.

Loop Quantum Photonic Chip for Coherent Multi‐Time‐Step Evolution
Laser &Photonics Reviews, EarlyView.A loop quantum photonic chip (Loop‐QPC) enabling efficient multi‐step quantum simulation in a single run is demonstrated. Combining recirculating loops with cycle‐or‐measure control, Loop‐QPC eliminates repeated reprogramming and reduces loss. Experimental demonstration of three‐step unitary evolution confirms high‐fidelity operation, showcasing the ...

Certain isometries related to the bilateral laplace transform
Mathematical Modelling and Analysis, 2006 We study certain isometries between Hilbert spaces, which are generated by the bilateral Laplace transform In particular, we construct an analog of the Bargmann‐Fock type reproducing kernel Hilbert space related to this transformation. It is shown

Antiferromagnetic Chains in a Monolayer of Molecular Qubits Assembled on Graphene
Small, EarlyView.This work explores the deposition onto graphene of a dithiazole‐based molecular qubit, [Cu(dttt)2], (dttt− = 1,3,2‐dithiazole‐4‐thione‐5‐thiolate), under ultra‐high vacuum conditions. Analytical techniques, including STM, XPS, and X‐ray absorption, reveal the molecular arrangement and magnetic interactions, emphasizing the role of vdW interactions in ...
