We report experimental evidence of ballistic hole transport in one-dimensional quantum
wires gate-defined in a strained SiGe/Ge/SiGe quantum well. At zero magnetic field, we …

Utilizing an innovative combination of scanning-probe and spectroscopic techniques,
supported by first-principles calculations, we demonstrate how electron-beam exposure of …

The mass production and the practical number of cryogenic quantum devices producible in
a single chip are limited to the number of electrical contact pads and wiring of the cryostat or …

We consider quantum point contact (QPC) defined within a disordered two-dimensional
electron gas as studied by scanning gate microscopy. We evaluate the conductance maps in …

Conduction electrons interacting with a dynamic impurity can give rise to a local Fermi liquid.
The latter has the same low-energy spectrum as an ideal Fermi gas containing a static …
