Krüger-Iwahara Lab
Machine-translated · View original
The lab uses computation to uncover the behavior of electrons inside materials.
AboutAbout the lab
Reading what is inside a material from the shape of its spectrum.
Krüger-Iwahara Lab studies the electronic states of materials through theory and computation.
The lab consists of two groups: the Krüger Group and the Iwahara Group.
Its targets are the electronic structure and magnetism of surfaces, interfaces, and new nanoscale materials.
It uses first-principles calculations to obtain ground-state properties, and calculates X-ray absorption and photoelectron spectra.
The lab also develops its own new methods for calculating spectra, based on multiplet and multiple scattering theory.
Key terms
- First-principles calculation
- A method of calculating the properties of materials from the fundamental equations of quantum mechanics, without fitting to experimental values
- X-ray absorption spectroscopy
- A method that measures how X-rays are absorbed in order to investigate the bonding and magnetism of each element
- Photoelectron spectroscopy
- A method that shines light on a material and measures the energy of the emitted electrons in order to investigate its electronic states

ResearchResearch themes
The lab studies the electronic and magnetic properties of new nanomaterials such as surfaces, interfaces, TiO2 nanotubes, and metal-organic molecules. It obtains ground-state properties through first-principles electronic structure calculations and calculates X-ray absorption and photoelectron spectra.
*Illustrative imageCalculating X-ray Absorption Spectra of Transition Metals
L2,3-edge X-ray absorption spectroscopy of transition metals is a powerful tool for determining the coordination, bonding, and magnetism of each element. The lab developed a multichannel multiple scattering theory that incorporates the effect of the core hole, and was the first to correctly reproduce the spectrum of TiO2.
*Illustrative imageComputational Methods for Angle-Resolved Photoemission
For angle-resolved photoemission spectroscopy with ultraviolet light and for photoelectron diffraction, the lab developed a new computational method based on real-space multiple scattering. Using the Cu-3d bands of the Cu(111) surface as an example, it examines how initial-state and final-state effects intertwine.
*Illustrative imageTheory of Spin-Resolved Resonant Photoemission
The lab developed a first-principles method for calculating resonant photoemission measured with angle and spin resolution. It showed that the strongly spin-polarized photoelectrons seen in antiferromagnets arise not from local magnetic moments but from the transfer of angular momentum from light to the electron spin.
*Illustrative imageNanoscale Density Fluctuations
Thermodynamic quantities of liquids are linked to density fluctuations and can be calculated with Kirkwood-Buff integrals. For this integral, which converges poorly with the usual approach, the lab derived exact expressions for finite volumes and showed that they converge much faster.
