We investigate the effects of spin-momentum locking on the interference and diffraction patterns due to a double- or single-slit in an electronic Gedankenexperiment. We show that the inclusion of the spin-degree-of-freedom, when coupled to the motion direction of the carrier—a typical situation that occurs in systems with spin–orbit interaction—leads to a modification of the interference and diffraction patterns that depend on the geometrical parameters of the system.

Theoretical study on slit experiments in Rashba electron systems
We develop a theory of designing slit experiments in two-dimensional electron systems with the Rashba spin-orbit interaction. By simulating the spatiotemporal dynamics of electrons passing through a
Design and characterization of electrons in a fractal geometry
TLDR
This work shows how arrays of artificial atoms can be defined by controlled positioning of CO molecules on a Cu (111) surface2–4, and how these sites couple to form electronic Sierpiński fractals, which are artificially created by atomic manipulation in a scanning tunnelling microscope.
Principles of Optics
Robust zero-energy modes in an electronic higher-order topological insulator
TLDR
A higher-order topological insulator is realized in a breathing kagome lattice built by patterning CO molecules on a Cu(111) surface and protected by a generalized chiral symmetry, which leads to a particular robustness against perturbations.
Wave-Particle Duality in Complex Quantum Systems.
TLDR
This Perspective elaborate how randomness induced by this very quantum property can be discerned from the stochasticity ubiquitous in complex systems already on the classical level and argues that in the study of increasingly complex systems, such distinction requires the analysis of single incidents of quantum dynamical processes.
Quasiparticle Interference Studies of Quantum Materials.
TLDR
It is demonstrated how quasiparticle interference measurements entail mesoscopic size quantization and the electronic phase coherence in semiconducting nanowires; helical spin protection and energy-momentum fluctuations in a topological insulator; and the structure of the Bloch wave function and the relative insusceptibility of topological electronic states to surface potential in aTopological Weyl semimetal.
Experimental realization and characterization of an electronic Lieb lattice
TLDR
An electronic Lieb lattice formed by the surface state electrons of Cu(111) confined by an array of CO molecules positioned with a scanning tunneling microscope (STM) is reported, which is equivalent to a super-Lieb lattices at higher energies.
Quantum interactive learning tutorial on the double-slit experiment to improve student understanding of quantum physics
TLDR
The development and evaluation of a research-validated Quantum Interactive Learning Tutorial (QuILT) which makes use of an interactive simulation to improve student understanding of the double-slit experiment and strives to help students develop a good grasp of foundational issues in quantum mechanics.
Dual nature of magnetic dopants and competing trends in topological insulators
TLDR
It is demonstrated that magnetic order and gapless states can coexist, and this is the result of the delicate balance between two opposite trends, that is, gap opening and emergence of a Dirac node impurity band, both induced by the magnetic dopants.
