Semiconductor excitons are composite particles consisting of fermionic carriers. Nevertheless they are considered as paradigmatic candidates for bosonic condensation and the formation of macroscopic coherence in solids. To address both effects, the kinetics of exciton thermalization is studied, including their composite fermionic character. This way, exciton condensation based on the primary assumption of a bosonic thermalization is questioned. In this light, also discussed is whether a recently observed decrease of linewidths at increasing exciton density can be related to a signature for emerging excitonic coherence.

Topological insulators in two-dimensional systems are well-understood within the context of free-fermion systems. Nevertheless, comprehending their strongly interacting counterparts presents a significant challenge. Here, the authors developed an innovative lattice model based on fermionic charge decorations. The model furnishes a rigorous mathematical framework for delving into fermionic symmetry-protected topological phases that conserve charge, among other types of symmetries. Notably, this research expands the existing theoretical landscape by presenting an exactly solvable Hamiltonian with a finite local Hilbert space and a sophisticated classification scheme for continuous symmetries.

The orbital Rashba effect describes the formation of chiral orbital angular momentum textures upon inversion symmetry breaking at surfaces or interfaces. Here, the authors unveil a pronounced anisotropic spin-orbit splitting with a Rashba-type spin polarization in the electronic interface states in the model system Te/Au(100). Exploring the momentum-dependent response of inversion symmetry breaking, they particularly demonstrate that the orbital texture leads to a strongly anisotropic spin and orbital Rashba effect. These findings will provide a valuable contribution to the discovery and understanding of future “orbitronic” phenomena.
