Abstract Quasi-one-dimensional systems exhibit many-body effects elusive in higher dimensions. A prime example is spin-orbital separation, which has been measured by resonant inelastic X-ray scattering (RIXS) in Sr2CuO3. We derive the time-resolved RIXS spectrum of Sr2CuO3 under the action of a t...

Insight into the Quantum World

Michael Nicklas; Supervised by Prof. Dr. Milena Grifoni,
Keywords: Condensed Matter, Master Equation, Quantum Dot, Quantum Transport, Theory Project

Michael Nicklas has studied and obtained his PhD within the research orientated program "Physics advanced". He investigated quantum transport in individual carbon nanotubes and developed new theoretical tools for their description. Schrodingers cat The paradox of coexistence or superposition...

Simulation Based Density Scans On Different 2D Colodial System Configurations

Johannes Schumann; Supervised by Prof. Dr. Michael Schmiedeberg,
Keywords: Computational Project, Condensed Matter, Quasicrystal, Theory Project

In a research project Johannes Schumann from Physics Advances explored how colloidal quasicrystals can be obtained by tailoring the interactions between the particles. Quasicrystals are well-ordered structures that do not posses any periodicity. Therefore, there is no unit cell and the rotational sy...
