The inclusion of charging and spin-exchange interactions within the universal Hamiltonian
description of quantum dots is challenging as it leads to a non-Abelian action. Here we …

We calculate the tunnelling density of states (TDoS) for a quantum dot in the Coulomb-
blockade regime, using a functional integral representation with allowing correctly for the …

The mesoscopic Stoner instability is an intriguing manifestation of symmetry breaking in
isolated metallic quantum dots, underlined by the competition between single-particle …

We use a many-body rate-equation approach to calculate the thermopower of a quantum dot
in the presence of an exchange interaction. At temperatures much smaller than the single …

We present a comprehensive pedagogical discussion of a family of models describing the
propagation of a single particle in a multicomponent non-Markovian Gaussian random field …

We study sequential tunneling through a metallic nanoparticle close to the Stoner instability
coupled to parallel magnetized electrodes. Increasing the bias voltage successively opens …

The physics of quantum dots is depicted succinctly by the universal Hamiltonian, where only
zero-mode interactions are included. In the case in which the latter involve charging and …

We explore the static longitudinal and dynamic transverse spin susceptibilities in quantum
dots and nanoparticles within the framework of the Hamiltonian that extends the universal …
