Theoretical ideas and experimental results concerning high-temperature superconductors
are reviewed. Special emphasis is given to calculations performed with the help of …

Monte Carlo simulations have become an established and useful method for treating
problems in classical statistical physics. Although the first attempts to apply these ideas to …

The transport coefficients of the Anderson model are calculated by extending Wilson's
numerical renormalization group method to finite-temperature Green functions. Accurate …

First principle calculation of the QCD spectral functions (SPFs) based on the lattice QCD
simulations is reviewed. Special emphasis is placed on the Bayesian inference theory and …

We report the details of an application of the method of maximum entropy to the extraction of
spectral and transport properties from the imaginary-time correlation functions generated …

We present in detail a formulation of the shell model as a path integral and Monte Carlo
techniques for its evaluation. The formulation, which linearizes the two-body interaction by …

We give a detailed presentation of our recent scheme to include correlation effects in
molecular transport calculations using the nonequilibrium Keldysh formalism. The scheme is …

We compute the current as a function of voltage for resonant tunneling through an Anderson
impurity in the low-temperature, Kondo, regime. The differential conductance curve has the …

Narrow band materials (transition metals and rare‐earth elements compounds) often reveal
anomalous physical properties. Their electronic structure is strongly renormalized by …

We compute the nonlinear current-voltage characteristic for resonant tunneling through an
Anderson impurity. For the symmetric Anderson model with the impurity equally coupled to …
