A Bayesian approach to spectroscopic depth sectioning for locating dopant atoms
Journal of Microscopy, EarlyView.Abstract Locating dopants in 3D is of great interest as advanced materials and devices increasingly rely on control at atomic dimensions, and microscopy tools are constantly in development for this purpose. One potential tool is electron energy loss spectroscopy (EELS) depth sectioning, where a core‐loss signal is collected as a function of electron ...

, 2005 Banach spaces of analytic functions such as the Hardy spaces and the Bergman spaces have been well investigated in the past half century. However, basic facts concerning Fock spaces remain scattered throughout literature.

四川大学学报. 自然科学版, 2020 In this paper, we obtain the equivalent characterizations for the boundedness,compactness, and Schatten class properties of the product of Volterra type integral andcomposition operators between generalized Fock spaces in terms of certain Berezin ...

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⁎

On products of some Toeplitz operators on polyanalytic Fock spaces [PDF]
, 2020 summary:The purpose of this paper is to study the Sarason's problem on Fock spaces of polyanalytic functions. Namely, given two polyanalytic symbols $f$ and $g$, we establish a necessary and sufficient condition for the boundedness of some Toeplitz ...

The Huang–Yang Formula for the Low‐Density Fermi Gas: Upper Bound
Communications on Pure and Applied Mathematics, Volume 79, Issue 8, Page 1919-1972, August 2026.ABSTRACT We study the ground state energy of a gas of spin 1/2$1/2$ fermions with repulsive short‐range interactions. We derive an upper bound that agrees, at low density ϱ$\varrho$, with the Huang–Yang conjecture. The latter captures the first three terms in an asymptotic low‐density expansion, and in particular the Huang–Yang correction term of order

Generalization of Gisin’s theorem to quantum fields
New Journal of PhysicsWe generalize Gisin’s theorem on the relation between the entanglement of pure states and Bell non-classicality to the case of mode entanglement of separated groups of modes of quantum fields extending the theorem to cover also states with undefined ...

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.

Natural Sciences, Volume 6, Issue 3, July 2026.Within quantum chemistry, density functional theory (DFT) is a revolution. This serves as an example of a multitude of other scientific events, supporting the idea that revolutions are always large, if observed with the appropriate magnification. ABSTRACT Distinguishing scientific revolutions from normal science is a subjective, conflicting matter ...
