Properties of Nuclear and Neutron Matter and Thermodynamic Consistency in a Nonlinear Mean-field Approximation

Properties of nuclear and neutron matter are discussed in a nonlinear σ-ω-ρ mean-field approximation with self-interactions and mixing-interactions of mesons and baryons. The nonlinear interactions are renormalized by employing the theory of conserving approximations, which results in a thermodynamically consistent approximation that maintains Hugenholtz-Van Hove theorem and Landau’s requiremen...

Dynamical Mean Field and Dynamical Cluster Approximations

We present a pedagogical discussion of the dynamical mean field and dynamical cluster approximations. PACS: ...

Nonequilibrium dynamical mean-field theory.

The many-body formalism for dynamical mean-field theory is extended to treat nonequilibrium problems. We illustrate how the formalism works by examining the transient decay of the oscillating current that is driven by a large electric field turned on at time t=0. We show how the Bloch oscillations are quenched by the electron-electron interactions, and how their character changes dramatically f...
