Talk Description
This talk presents how quantum-mechanical models can be used to understand the electronic and vibrational behaviour of carbon-based materials. It considers Raman scattering in polyacetylene, where computational methods are used to connect the interaction of light with a material to its characteristic spectral features, alongside tight-binding calculations that describe the electronic structure of graphene and the influence of neighbouring atoms within its lattice. The presentation will introduce the physical ideas behind Raman scattering, electronic transitions, molecular vibrations, and lattice models before showing how these concepts are translated into practical calculations. Particular attention will be given to the use of the Kramers-Heisenberg-Dirac framework, density functional theory, and nearest-neighbour tight-binding models to relate microscopic quantum behaviour to observable material properties.
The talk is intended for a broad scientific audience. No prior knowledge of Raman spectroscopy or Quantum Materials is required, as all relevant principles and terminology will be explained from the outset.
Research Description
The presented research follows from a study conducted by Kaya during her fellowship under the Center of Integrated Quantum Materials (CIQM) at Harvard University, under the supervision of Eric Heller.
Bio
Fikriye C. I. Kaya is an Assistant Professor at OsloMet, where she teaches thermodynamics, fluid mechanics, and dynamic systems and control. She holds a Ph.D. in particle physics from Tufts University and has contributed to research with the ATLAS experiment at CERN. Her work spans experimental particle physics, computational modelling of quantum materials, and physics education, with a particular interest in making mathematically demanding scientific ideas clear, accessible, and relevant across disciplines.
About the qGAP seminar series
This term, qGap will consist of journal-club style talks discussing interesting papers in quantum science and technology.
We aim to have a biweekly research seminar, with various people presenting research results, or discussing papers in a journal club style.
Ideally, everyone would have read the weekly reading before coming to the seminar, as they will be structured as a discussion rather than a lecture. We particularly encourage Master's students to come.
The seminars are at 14.15 in the CCSE seminar room (4th floor Physics building, East Wing), as per usual
If you have something you would like to present (whether own research or a journal-club style talk), please do not hesitate to get in touch!
