Ab-initio Modelling of Molecular Processes Involving the CO system

by Oscar Mabuza

Department of Physics, University of Eswatini

In this research work, chemical reactions that are important in cold plasma environments, such as primordal and pre-galactic gas reactions, interstellar gas clouds chemistry, planetary ionosphere chemistry and laboratory plasmas are theoretically studied. Structure calculations are combined with scattering calculations to study the reaction dynamic on a potential energy curve either quantum mechanically or through the semi-classical Landau-Zener method. Both time independent and time dependent Schrödinger equations are utilized. Mutual neutralization (MN) in collisions of C$^+ + $ O$^-$ and C$^- +$ O$^+$ is studied using the semi-classical Landau-Zener method. This theoretical study requires computation of non-adiabatic couplings among the excited electronic states and hence the rotational angle that is used in the transformation matrix. The electronic states are transformed from an adiabatic to a diabatic representation. Cross sections and final state distributions are calculated. The cross section is found to obey Wigner's threshold law at low collision energy. The direct mechanism for dissociative recombination (DR) of CO$^+$ is also studied. Scattering calculations using the complex Kohn variational method are used and Electron capture and dissociation are modelled using a one-dimensional wave packet which is propagated using the Crank-Nicholson propagator. The results show that the cross section obtained display threshold behaviour and these are compared to cross sections of other systems. Final state distribution is also calculated for this process.

A Hands-on Introduction to Quantum Computing

by Dr. Makhamisa Senekane

Department of Physics and Electronics, National University of Lesotho, Roma, Lesotho

Quantum Information Processing (QIP), which is also dubbed as the second quantum revolution, uses quantum mechanical concepts such as superposition, entanglement, and interference in order to process information. Some of the sub-fields of QIP include quantum cryptography, quantum computing, quantum games, and quantum communication. In this talk, we will explore the potentital of quantum information processing, with emphasis on quantum computing. The focus of the talk will first be on the introduction to quantum computing, and then on the hands-on implementation of quantum computing algorithms.

Computational Modelling of Cold Molecular Collisions

by Dr. Sifiso M. Nkambule

In this talk I will give an overview of charge transfer and molecular break-up reactions involving small systems that are currently studied by our research group. All these reactions involve a transfer of charge and they occur at low collision energies. These Reactions are relevant to understanding planetary atmospheres and this is essential in understanding global warming and stratospheric ozone depletion. Employing quantum chemistry and electron scattering calculations, the electronic states involved in the reactions and their couplings are computed. Different quantum chemistry calculations are performed and we investigate their influence on the curve crossing distance and the cross section. The electronic structure calculations are compared with electron scattering calculation at short internuclear distances. Autoinization widths are also computed and they are included in the nuclear Schr¨odinger equation using the “local Boomerang model”. The nuclear dynamics are studied using time-independent quantum techniques. A semi-classical Landau-Zener study is also performed. Reaction cross sections are then computed and compared with other theoretical and measured data available.

Electrokinetic Phenomena in Soft Nanomembranes

by Dr. Mpumelelo Matse

In and around porous systems with at least one characteristic dimension below a few nanometers, solid/liquid interfaces play a key role in surface-charge-governed transport, separation processes and energy storage devices. Nanopores with well-defined geometry and chemical characteristics have emerged as valuable tools to unravel interactions between external and induced electric fields and the underlying transport, in the presence of embedded charges. In this talk, we present results from our recent theoretical and numerical investigations of electrokinetic effects in soft nanopores with uniformly distributed surface charges, carried out within mean-field approximations. The aim is to provide a theoretical framework through which one can access a comprehensive understanding of the coupling between electrokinetic transport, double-layer charging and wall deformations in charged nanochannels embedded in soft polymeric membranes.

Studies of the partonic structure of the nucleon fromGeneralized Parton Distributions (GPDs): Measurement of (Exclusive) Deeply Virtual Compton Scattering(DVCS) & π0 Electroproduction Cross Section a the Thomas Jefferson National Accelerator Facility

by Dr. M. Dlamini

Up to this point, the physics community is confident about the elementary composition of nucle-ons, that is, at the most fundamental level, matter is composed of quarks and gluons. This is to sayit is now common understanding that a nucleon, proton or neutron, is basically made up of some“valence” quarks and an infinite quark-gluon sea. That is good enough to describe the static proper-ties of matter, or in this context, nucleons. An ultimate understanding of nucleon structure requiresan understanding of the dynamic properties of such systems. We need to understand how quarksform their “quark communities” and the physics that governs transition from one quark system tothe next. Such a complete understanding of nucleon structure requires the use of more degrees offreedom in describing nucleon systems. Generalized Parton Distributions (GPDs) have emerged asthe “new kid on the street” in the pursuit of a more complete nucleon description because theypromise a tomographic picture of the interior landscape of such systems. A complete understandingof nucleon structure requires the knowledge of both chiral-odd and chiral-even generalized partondistributions (GPDs). Hitherto, chiral-odd GPDs have been elusive since the processes they par-ticipate in are suppressed at leading order. Recently, pseudoscalar meson production, in particularneutral meson (π0) production, has been identified as sensitive to chiral-odd GPDs at leading orderand therefore a golden channel to measure them. Exclusiveπ0electroproductionp(e,e’π0)p’andphotoproductionp(e,e’γ)p’channels have been measured (simultaneously) by experiment E12-06-114 in Hall A of JLab with the new 12 GeV upgrade. Cross sections have been measured at threefixed Bjorken-x(xB): 0.35, 0.48 and 0.6 in the Q2 range 3 to 9 GeV2. In the case ofπ0electro-production, the different response terms of the cross section:σU=σT+σL,σLTandσT Twereextracted as functions of the momentum transfer to the protont. The results are interpreted in thehandbag formalism of asymptotic freedom in perturbative quantum chromodynamics. The datawas compared to transversity GPD models. In this talk we will give a brief overview of the GPDprogram at JLab, in particular experimental hall A. We will present preliminary photoproductionresults in the 12 GeV era. We will also discussπ0electroproduction results as well. Time permitingwe will also look at an overview of the GPD program around the world, in particular, facilities likeCERN come to mind.

Phase field crystal modelling of complex crystalline structures.

by Prof. S. Mkhonta

Mathematics and computation have long played a central role in materials science and engineering, with efforts increasingly focused on the nanoscale. In this talk, I will present some of our recent work on the application of the phase-field crystal (PFC) formalism to examine the basic mechanisms governing the formation of a broad range of crystalline and armorphous states in two dimensions. The world of twodimensional crystals is of great significance for the design and study of structural and functional materials with novel properties. The PFC model provides a systematic path to predict the influence of lattice symmetry on both the elastic constants and dynamics of crystalline and defected systems at larger time scales that are not accessible with other microscopic simulation methods (classical Molecular Dynamics or Quantum Density Functional Theory). I will also demonstrate some recent work on the application of the PFC framework to study binary materials such a hexagonal boron-nitride and the moiré patterns that are generated by layered systems.

Magnetic Properties of the (Cr98.4Al1.6)100-yMoy Alloy System

by Dr. B. Muchono

UChromium is an archetypal antiferromagnetic material with magnetic properties that are sensitively modified by various diluents. Alloying Cr with Al results in a decrease in the Néel temperature (TN) with increasing Al content, reaching a minimum near 2 at.% Al and thereafter increases on further addition. The magnetic properties of the Cr- Al alloy system are explored further in this study through the addition of Mo which is iso-electronic with Cr. Alloying Cr-Al with Mo to form (Cr98.4Al1.6)100-yMoy alloy system yields interesting results in which the alloy system is driven to quantum criticality through electron-hole pair breaking effects due to electron scattering by Mo solute atoms. Results of the temperature dependence of electrical resistivity, Seebeck coefficient , thermal conductivity , magnetic susceptibility , specific heat , Hall coefficient and neutron diffraction in the temperature range 2 K ≤ T ≤ 390 K are reported. The findings indicate a suppression of the Néel temperatures to below 2 K for alloy concentrations y >= 4.5
