Quantum mechanics (QM) textbooks both shape classroom instruction and reflect the pedagogical strategies of the lecturers and researchers who write them. This study analyzes the didactic structures of university-level QM textbooks across nations and eras by mapping the chapter-level placement of mathematical formalisms, illustrative physical systems, foundations and interpretations. The...

10. Characterizing the coupling between plasmonic nano-antennas and an atomically thin semiconductorHannah Unterberg29/09/2026, 18:10Semiconductor PhysicsPoster
The combination of plasmonic nano-antennas and atomically thin semiconductors offers an ideal platform to explore light matter coupling on the nanoscale. One reason is that the natural Bohr radius of excitons in these materials is in the range of a few nanometers and therefore significantly smaller than the optical diffraction limit, i.e. the resolution of standard far-field optical setups. In...

Compact and efficient light sources are essential for integrated photonic circuits, yet their direct integration with silicon-based platforms remains challenging due to the inefficient light emission of silicon. III–V semiconductor nanowires offer a promising route towards nanoscale light sources, combining a small footprint and efficient strain relaxation with the direct band gap required for...

The combination of scanning transmission X-ray microscopy (STXM) and X-ray fluorescence (XRF) analysis enables the simultaneous acquisition of elemental distribution maps and multiple transmission imaging modes. In the soft and tender X-ray range, this combination has become an increasingly powerful tool for materials science, biomedical, and environmental research.

Polyatomic molecular ions offer new opportunities for precision spectroscopy and quantum control due to their rich internal structure. At the same time, their complex energy levels and lack of cycling transitions makes their state-preparation and readout challenging. I will present a cryogenic trapped-ion experiment which we recently developed and our first results demonstrating chemistry with...

Scanning nitrogen-vacancy (NV) magnetometry is a powerful technique for nanoscale magnetic imaging. In this approach, the conventional atomic force microscopy tip is replaced by a diamond nanopillar containing a single NV center, which serves as a highly sensitive local magnetic field sensor. By scanning the NV center over a sample, the magnetic stray field can be mapped with high spatial...

High-entropy transition-metal diborides (HEDBs; HETMB$_2$) retain the hexagonal AlB$_2$ structure while introducing severe multication disorder, raising practical questions about how large and how random a supercell must be for reliable first-principles predictions.

Are the spectroscopic properties of plasmon- and photon-induced carriers fundamentally different? This question is crucial for advancing plasmonic energy conversion. Initial studies have suggested characteristic energy and momentum distributions for the photoemission of both bulk plasmon resonances and surface plasmons. For surface plasmons, however, the separation of plasmon and...

Germanium has emerged as a promising platform for superconductor–semiconductor hybrid devices [1,2] due to its compatibility with existing CMOS technology, high carrier mobility [3], and a relatively strong spin–orbit coupling [4]. A critical requirement for such hybrid systems is the realization of a transparent and well-defined interface between the superconductor and the semiconductor at...

Ultraviolet (UV) photonic integrated circuits (PICs) have many interesting applications, such as biochemical sensing, atomic clocks, and UV Raman spectroscopy. For realizing PICs in the UV spectral range, materials with a large bandgap are required to facilitate low optical losses.

We characterize the lowest optically active excitation of a one-dimensional extended Hubbard chain with on-site repulsion $U_0$ and nearest-neighbor repulsion $U_1$. Two complementary natural-orbital diagnostics disentangle the character of the excitation: the one-particle-one-hole (1p1h) weight $W_{1p1h}$, which measures how completely a single particle-hole picture accounts for the...

When a metal is irradiated with an ultrashort optical laser pulse, the electrons become excited, disturbing the electron distribution into a state far from equilibrium. The subsequent relaxation dynamics determine how the absorbed energy is redistributed within the electronic system and transferred to the lattice, making electron thermalization a key process in ultrafast laser-matter...
