Common Trends of Chiral Induced Spin Selectivity and Optical Dichroism with Varying Helix Pitch: A First‐Principles Study

Israel Journal of Chemistry, Volume 62, Issue 11-12, December 2022., 2022
Abstract Electrons ransported through a chiral molecule become spin−polarized; this phenomenon is known as chiral induced spin selectivity (CISS). It has implications for spintronics, for electrochemical and enantioselective reactions, and for electron transfer in biological systems.

Chirality Induced Spin Selectivity – the Photoelectron View

Israel Journal of Chemistry, Volume 62, Issue 11-12, December 2022., 2022
Abstract In this short overview we discuss the manifestation of the chirality‐induced spin selectivity (CISS) effect in photoelectron spectroscopy experiments with direct spin analysis. Various systems, from the initially investigated monolayers of molecular biosystems and organic hepta‐helicene to recent chirally grown solid oxide films, are evaluated.

Infinitely many solutions for Hamiltonian system with critical growth

Advances in Nonlinear Analysis
In this article, we consider the following elliptic system of Hamiltonian-type on a bounded domain:−Δu=K1(∣y∣)∣v∣p−1v,inB1(0),−Δv=K2(∣y∣)∣u∣q−1u,inB1(0),u=v=0on∂B1(0),\left\{\begin{array}{ll}-\Delta u={K}_{1}\left(| y| ){| v| }^{p-1}v,\hspace{1.0em ...

Quantum chemical rovibrational analysis of aminoborane and its isotopologues

Journal of Computational Chemistry, Volume 44, Issue 3, Page 298-306, January 30, 2023., 2023
The rovibrational spectrum of aminoborane has been investigated by high‐level ab initio methods based on a multidimensional potential energy surface obtained from explicitly correlated coupled‐cluster calculations. Abstract Aminoborane, H2NBH2 and its isotopologues, H2N10BH2, D2NBD2, and D2N10BD2, have been studied by high‐level ab initio methods.

Ultrafast Demagnetization Through Femtosecond Generation of Non‐Thermal Magnons

Advanced Physics Research, EarlyView.
A fully ab initio parametrized model is developed to describe out‐of‐equilibrium magnon dynamics in ferromagnetic metals. Applying this model to ultrafast laser‐induced demagnetization, it is revealed that the generation of non‐thermal magnons provides a sizable demagnetization within 200 fs in excellent comparison with experiments, which establishes ...
