Aspects of integrability in a classical model for non-interacting fermionic fields [PDF]

open access: yes, 2015
In this work we investigate the issue of integrability in a classical model for noninteracting fermionic fields. This model is constructed via classical-quantum correspondence obtained from the semiclassical treatment of the quantum system.

A Simple Model for Halogen Bond Interaction Energies

open access: yesInorganics, 2019
Halogen bonds are prevalent in many areas of chemistry, physics, and biology. We present a statistical model for the interaction energies of halogen-bonded systems at equilibrium based on high-accuracy ab initio benchmark calculations for a range of ...

Role of Mineral Surfaces in Prebiotic Chemical Evolution. In Silico Quantum Mechanical Studies

open access: yesLife, 2019
There is a consensus that the interaction of organic molecules with the surfaces of naturally-occurring minerals might have played a crucial role in chemical evolution and complexification in a prebiotic era.

Computational solution of atmospheric chemistry problems [PDF]

open access: yes
Extensive studies were performed on problems of interest in atmospheric chemistry. In addition to several minor projects, four major projects were performed and described (theoretical studies of ground and low-lying excited states of ClO2; ground and ...

Theoretical Chemistry Course for Students in Chemistry

open access: yes, 2021
In this work, the teaching content of a theoretical-chemistry (TC) course is reformed, establishing a theoretical contents from micro- to macro-system, and comprehensively introducing the theory of chemical reaction to undergraduate students in chemistry. In order to develop such TC course based on the general physical-chemistry course, we focus on the

Substitution effect and effect of axle’s flexibility at (pseudo-)rotaxanes

open access: yesBeilstein Journal of Organic Chemistry, 2014
This study investigates the effect of substitution with different functional groups and of molecular flexibility by changing within the axle from a single C–C bond to a double C=C bond.

The magnetic fields of forming solar-like stars

open access: yes, 2010
Magnetic fields play a crucial role at all stages of the formation of low mass stars and planetary systems. In the final stages, in particular, they control the kinematics of in-falling gas from circumstellar discs, and the launching and collimation of ...
