The small energy anomaly in the single-particle density of states of disordered interacting systems is studied for the zero-dimensional case. This anomaly interpolates between the nonperturbative Coulomb blockade and the perturbative limit, the latter being an extension of the Altshuler-Aronov zero-bias anomaly at d=0. Coupling of the zero-dimensional system to a dissipative environment leads to effective screening of the interaction and a modification of the density of states. \textcopyright…

Nonlinear Sigma Model for Disordered Media: Replica Trick for Non-Perturbative Results and Interactions
Starting from the seminal papers of Wegner [1] and Efetov [2], a field-theoretical description based on the nonlinear σ model (NLσM) has become one of the main analytical approaches to various
Weak charge quantization on a superconducting island
We consider Coulomb blockade on a superconductive quantum dot strongly coupled to a lead through a tunneling barrier and/or normal diffusive metal. Andreev transport of the correlated pairs leads to
Interacting resonant level coupled to a Luttinger liquid: Population vs. density of states
Abstract We consider the problem of a single level quantum dot coupled to the edge of a one-dimensional Luttinger liquid wire by both a hopping term and electron–electron interactions. Using
Spin and charge correlations in quantum dots: An exact solution
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 present an exact
A quantum dot close to Stoner instability: the role of Berry's Phase
The physics of a quantum dot with electron-electron interactions is well captured by the so called "Universal Hamiltonian" if the dimensionless conductance of the dot is much higher than unity.
Transverse spin fluctuations in metallic quantum dots
We present a full fledged quantum mechanical treatment of the interplay between the charge and spin zero mode interactions in quantum dots. Transverse spin fluctuations are shown to suppress the
