Effects of topological boundary conditions on Bell nonlocality

open access: yesPhysical Review A
Bell nonlocality is the resource that enables device-independent quantum information processing tasks. It is revealed through the violation of so-called Bell inequalities, indicating that the observed correlations cannot be reproduced by any local hidden variable model.

Quantum Chemistry Investigation of Linear and Nonlinear (chir)optical Properties of Oligoamide Foldamers

open access: yesChemistryEurope, EarlyView.
The linear and nonlinear (chir)optical properties of four oligoamide foldamers with different donor groups are studied by means of time‐dependent density functional theory calculations. It is shown that stronger donors yield larger hyperpolarizabilities due to low‐lying charge–transfer states. The agreement with the experiments concerning the key bands

Controllability of abstract fractional differential evolution equations with nonlocal conditions

open access: yes, 2017
In this paper, the controllability of a class of fractional differential evolution equations with nonlocal conditions is investigated. Sufficient conditions which guarantee the controllability of fractional differential evolution equations are obtained ...

Ghost effect from Boltzmann theory

open access: yesCommunications on Pure and Applied Mathematics, EarlyView.
Abstract Taking place naturally in a gas subject to a given wall temperature distribution, the “ghost effect” exhibits a rare kinetic effect beyond the prediction of classical fluid theory and Fourier law in such a classical problem in physics. As the Knudsen number ε$\varepsilon$ goes to zero, the finite variation of temperature in the bulk is ...

Study of Solutions to Some Functional Differential Equations with Piecewise Constant Arguments

open access: yesAbstract and Applied Analysis, 2012
We provide optimal conditions for the existence and uniqueness of solutions to a nonlocal boundary value problem for a class of linear homogeneous second-order functional differential equations with piecewise constant arguments.

Charge State Influence on Stability and Isomerism in Dehydrogenated PAHs: Insights from Anthracene, Acridine, and Phenazine

open access: yesChemPhysChem, Volume 26, Issue 6, March 15, 2025.
The ionization of anthracene, acridine, and phenazine has been explored, along with the removal of one and two hydrogen atoms, to provide valuable information for astrochemists and to understand the behavior of the resulting structures and their electronic reorganization. Abstract In this study, we systematically explored the stability and isomerism of

Tuning Pore Chemistry in Dioxin‐Linked Porous Organic Polymers for Enhanced High‐Pressure CO2 Uptake

open access: yesHelvetica Chimica Acta, EarlyView.
By tuning the pore structure of porous organic polymers, we can control their CO2 capture performance at different pressures. Post‐synthetic conversion of nitrile groups to amidoxime groups creates high‐affinity towards CO2 at low pressures, while the unmodified polymers achieve superior CO2 uptake of 57.4 wt% under high‐pressure conditions of 33 bar ...
