Modeling electronic and optical properties of III–V quantum dots—selected recent developments
Light: Science & Applications, 2022 Electronic properties of selected quantum dot (QD) systems are surveyed based on the multi-band k·p method, which we benchmark by direct comparison to the empirical tight-binding algorithm, and we also discuss the newly developed “linear combination of ...

High-Harmonic Generation in Solids: Bridging the Gap Between Attosecond Science and Condensed Matter Physics [PDF]
IEEE Journal of Selected Topics in Quantum Electronics, 2015 We review recent progress in understanding the dominant mechanism driving high-harmonic generation in solids. Three-dimensional two-band single active electron calculations predict that the major emission arises from the recombination of electron-hole pairs upon their creation and acceleration in the laser field, in analogy to atomic high-harmonic ...

Observation and control of the weak topological insulator state in ZrTe5
Nature Communications, 2021 Topological side surface, characterization of a weak topological insulator (WTI), has rarely been investigated. Here, Zhang et al. visualize a quasi-one dimensional, spin-momentum locked band on the side surface of the WTI candidate ZrTe5, and manipulate

Auger-spectroscopy in quantum Hall edge channels and the missing energy problem
Nature Communications, 2019 Energy relaxation crucially impacts transport properties of mesoscopic devices. Here the authors show that energy can be distributed between distant parts of the sample, which may provide a resolution to an outstanding puzzle concerning energy ...

Earthquake Nowcasting: Retrospective Testing in Greece
Entropy, 2023 Earthquake nowcasting (EN) is a modern method of estimating seismic risk by evaluating the progress of the earthquake (EQ) cycle in fault systems. EN evaluation is based on a new concept of time, termed ’natural time’.

Magnon-cooparons in magnet-superconductor hybrids
Communications Materials, 2022 Magnet-superconductor heterostructures provide a means to engineer unconventional spin-triplet Cooper pairs using ordinary superconductors. Here, a magnet-superconductor bilayer is predicted to host a composite quasiparticle consisting of spinful Cooper ...

Birotons and “Dark” Quantum Hall Hierarchies
Applied Sciences, 2022 A computational scheme is suggested to estimate neutral excitation energies in the fractional quantum Hall effect (FQHE) states. The FQHE states are systematized according to the Farey-number hierarchy structure.
