A Hybrid Semi‐Inverse Variational and Machine Learning Approach for the Schrödinger Equation

Advanced Physics Research, Volume 5, Issue 6, June 2026.
A hybrid semi‐inverse variational and machine‐learning framework is presented for solving the Schrödinger equation with complex quantum potentials. Physics‐based variational solutions generate high‐quality training data, enabling Random Forest and Neural Network models to deliver near‐perfect energy predictions.

Extended State Space for describing renormalized Fock spaces in QFT

, 2022
In quantum field theory (QFT) models, it often seems natural to use, instead of wave functions from Fock space, wave functions that are not square-integrable and have prefactors involving divergent integrals (known as infinite wave function ...

Dual Toeplitz operators on the weighted Fock spaces

四川大学学报. 自然科学版
With the successful characterization of the semi-commutativity of dual Toeplitz operators on the orthogonal complement of the Bergman space over the unit disk， dual Toeplitz operators on the orthogonal complement of analytic function spaces have ...

Deformed Fock spaces, Hecke operators and monotone Fock space of Muraki

Demonstratio Mathematica, 2012
Abstract The main purpose of this paper is to extend our previous construction of T-Fock spaces from a given Yang–Baxter operator satisfying the inequalities −1 ≤ T ≤ 1 to the constructions of T-symmetric Fock spaces related to the class of Yang–Baxter–Hecke operators meeting a weaker condition that T ≥ −1.

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

InfoMat, Volume 8, Issue 6, June 2026.
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 ...

Direct Evidence for a Carbon–Carbon One‐Electron σ‐Bond, or a Weak Carbon–Carbon Interaction?

ChemistryOpen, Volume 15, Issue 6, June 2026.
Experiments reporting the existence of a single‐electron C─C σ bond in a synthesized stable radical cation open up new perspectives in the study of the existence of chemical bonds. However, the supporting theoretical results at density functional theory cost do not seem to fully support this evidence.

Comparative Density Functional Theory Insights Into B16C16 and Si16C16 Nanocages for Sensing Oil‐Derived Fault Gases in Energy and Industrial Systems

ChemistryOpen, Volume 15, Issue 6, June 2026.
B16C16 and Si16C16 nanocages were investigated via DFT for sensing transformer oil fault gases (C2H4, CO, H2S). BC nanocages exhibit stronger adsorption, reduced energy gaps, enhanced electrical conductivity, and positive sensing responses compared to SiC. NCI and QTAIM analyses reveal covalent and partially covalent interactions.

Excitonic Theory of the Ultrafast Optical Response of 2D‐Quantum‐Confined Semiconductors at Elevated Densities

Advanced Quantum Technologies, Volume 9, Issue 6, June 2026.
In this work, an excitonic many‐body theory for the ultrafast optical response at elevated excitation densities for Wannier–Mott excitons is developed and applied to two distinct materials (GaAs quantum well and MoSe2 monolayer) as proponents of two different Coulomb‐interaction regimes.
