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

Molecular electronic devices currently serve as a platform for studying a variety of physical
phenomena only accessible at the nanometer scale. One such phenomenon is the highly …

We introduce an efficient method to simulate the dynamics of an interacting quantum
impurity coupled to noninteracting fermionic reservoirs. Viewing the impurity as an open …

The Kondo effect is a striking consequence of the coupling of itinerant electrons to a
quantum spin with degenerate energy levels. While degeneracies are commonly thought to …

We investigate the thermopower of single molecules weakly coupled to metallic leads. We
model the molecule in terms of the relevant electronic orbitals coupled to phonons …

Describing a quantum impurity coupled to one or more noninteracting fermionic reservoirs is
a paradigmatic problem in quantum many-body physics. While historically the focus has …

Dissipative quantum phase transition has been widely believed to occur in a Josephson
junction coupled to a resistor despite a lack of concrete experimental evidence. Here, on the …

The spin 1/2 entropy of electrons trapped in a quantum dot has previously been measured
with great accuracy, but the protocol used for that measurement is valid only within a …

Universality is a powerful concept, which enables making qualitative and quantitative
predictions in systems with extensively many degrees of freedom. It finds realizations in …

Quantum devices such as spin qubits have been extensively investigated in electrostatically
confined quantum dots using high-quality semiconductor heterostructures like GaAs and Si …
