We study quantum-impurity models as a platform for quantum thermometry. A single
quantum spin-1 2 impurity is coupled to an explicit, structured, fermionic thermal sample …

Twisted van der Waals materials have been shown to host a variety of tunable electronic
structures. Here we put forward twisted trilayer graphene (TTG) as a platform to emulate …

The emergence of flat bands in twisted bilayer graphene at the magic angle can be
understood in terms of a vanishing Fermi velocity of the Dirac cone. This is associated with …

Magnetic impurities in three-dimensional Dirac and Weyl systems are shown to exhibit a
fascinatingly diverse range of Kondo physics, with distinctive experimental spectroscopic …

The thermoelectric properties of hybrid system based on a single-level quantum dot coupled
to a ferromagnetic metallic lead and attached to the surface states of a three-dimensional …

We calculate exact zero-temperature real-space properties of a substitutional magnetic
impurity coupled to the edge of a zigzag silicenelike nanoribbon. Using a Lanczos …

Impurities act as in situ probes of nontrivial electronic structure, causing real-space
modulations in the density of states detected by scanning tunneling spectroscopy on the …

We study theoretically a triangular cluster of three magnetic impurities, hybridizing locally
with conduction electrons of a metallic host. Such a cluster is the simplest to exhibit …

An upper limit to the mass of the three-proton unbound nucleus Na 17 was measured to be
Δ M≤ 34.72 (6) MeV. The excitation energies, widths, and decay modes for one-and two …

We investigate Kondo physics in a host with a strongly diverging density of states. This study
is motivated by a recent work on vacancies in the graphene honeycomb lattice, whose …
