A review is given of various theoretical approaches for the equation of state (EoS) of dense
matter, relevant for the description of core-collapse supernovae, compact stars, and compact …

We review the physics of helium nanodroplets with emphasis on theoretical aspects that
have been the subject of recent research, like 3 He and mixed 3 He− 4 He droplets, vortices …

We calculated the equation of state of neutron matter at zero temperature by means of the
auxiliary field diffusion Monte Carlo (AFDMC) method combined with a fixed-phase …

We present a coupled cluster and linear response theory to compute properties of many-
electron systems at nonzero temperatures. For this purpose, we make use of the thermofield …

Thermofield dynamics has proven to be a very useful theory in high-energy physics,
particularly since it permits the treatment of both time-and temperature-dependence on an …

We report results of the equation of state of neutron matter in the low-density regime, where
the Fermi wave vector ranges from 0.4⩽ k F⩽ 1.0 fm-1. Neutron matter in this regime is …

Abstract The Coupled Cluster Method (CCM) is one of the most powerful and universally
applied techniques of quantum many-body theory. In particular, it has been used extensively …

We present a wave function representation for the canonical ensemble thermal density
matrix by projecting the thermofield double state against the desired number of particles …

We describe a procedure to systematically improve direct diagonalization results for few-
particle systems trapped in one-dimensional harmonic potentials interacting by contact …

We present a new high-order coupled cluster method (CCM) formalism for the ground states
of lattice quantum spin systems for general spin quantum number, s. This new “general-s” …
