Carbon nanotubes are a versatile material in which many aspects of condensed matter
physics come together. Recent discoveries have uncovered new phenomena that …

Over the past decade, transport measurements on individual single-wall nanotubes have
played a prominent role in developing our understanding of this novel carbon conductor …

PbTe nanowires coupled to a superconductor have recently been proposed as a potential
Majorana platform. The hallmark of the one-dimensional nature of ballistic nanowires is their …

Quantum impurity models, which describe how a local degree of freedom interacts with a
continuum, are central to condensed-matter physics. Such models may be naturally …

We report on a comprehensive study of spin-1 2 Kondo effect in a strongly coupled quantum
dot realized in a high-quality InAs nanowire. The nanowire quantum dot is relatively …

Energy band for single wall carbon nanotubes with spin–orbit interaction is calculated using
non-orthogonal tight-binding method. A Bloch function with spin degree of freedom is …

Quantum impurity models (QIMs) are ubiquitous throughout physics. As simplified toy
models they provide crucial insights for understanding more complicated strongly correlated …

In the original discussion of the Kondo effect, the increase of the resistance in an alloy such
as Cu0. 998Fe0. 002 at low temperature was explained by the antiferromagnetic coupling …

We study the SU (4) Kondo effect in carbon nanotube quantum dots, where doubly
degenerate orbitals form four-electron “shells.” The SU (4) Kondo behavior is investigated …

In a π-Josephson junction, the supercurrent's sign is reversed due to the dephasing of
superconducting pairs upon their traversal of the nonsuperconducting part. 0-π quantum …
