We review recent experimental and theoretical work on ultrasmall metallic grains, ie grains
sufficiently small that the conduction electron energy spectrum becomes discrete. The …

A variational principle is devised which optimizes the characteristic function at
thermodynamical equilibrium. The Bloch equation is used as a constraint to define the …

We present a self-contained theory for the exact calculation of particle number counting
statistics of noninteracting indistinguishable particles in the canonical ensemble. This …

We investigate fluctuations and even-odd effects in small superfluid systems at finite
temperature by means of the static path approximation (SPA) plus random-phase …

We formulate the finite-temperature relativistic Hartree-Bogoliubov theory for spherical
nuclei based on a point-coupling functional, with the Gogny or separable pairing force …

We review recent experimental and theoretical work on superconductivity in ultrasmall
metallic grains, ie grains sufficiently small that the conduction electron energy spectrum …

We assess the accuracy of finite-temperature mean-field theory using as a standard the
Hamiltonian and model space of the shell model Monte Carlo calculations. Two examples …

We utilize the shell model Monte Carlo method to study the structure of rare earth nuclei.
This work demonstrates the first systematic full oscillator shell with intruder calculations in …

We investigate the RPA correlations at finite temperature in the presence of thermal
fluctuations in the context of the microscopic static path approximation. The RPA correction …

We demonstrate that pairing phase transition (superfluid to normal) can be described quite
generally in terms of the thermodynamical properties after verifying the obtained level …
