Self-Consistent Tensor Product Variational Approximation for 3D Classical Models

We propose a numerical variational method for three-dimensional (3D) classical lattice models. We construct the variational state as a product of local tensors, and improve it by use of the corner transfer matrix renormalization group (CTMRG), which is a variant of the density matrix renormalization group (DMRG) applied to 2D classical systems. Numerical efficiency of this approximation is inve...

Self-consistent Skyrme quasiparticle random-phase approximation for use in axially symmetric nuclei of arbitrary mass

We describe a new implementation of the quasiparticle random-phase approximation (QRPA) in axially symmetric deformed nuclei with Skyrme and volume-pairing energy-density functionals. After using a variety of tests to demonstrate the accuracy of the code in 24,26Mg and 16O, we report the first fully self-consistent application of the Skyrme QRPA to a heavy deformed nucleus, calculating strength...

Self-consistent random-phase approximation for interacting electrons in quantum wells and intersubband absorption

For electrons with Coulomb interaction confined in a quantum well, we have developed an approach based on the Kadanoff-Baym-Keldysh technique to calculate equilibrium Green’s functions. This approach is based on iterative numerical computation of the retarded self-energy in the self-consistent random-phase approximation. For two subbands, at zero temperature, we have computed spectral functions...

Self-consistent random-phase approximation for a two-dimensional electron gas: Kadanoff-Baym-Keldysh approach

We have developed a method of finding equilibrium Green’s functions for an electron gas with Coulomb interaction within the Kadanoff-Baym-Keldysh approach. This method is based on iterative numerical computation of the retarded self-energy in the self-consistent random-phase approximation. For a two-dimensional electron gas, we have calculated numerically various one-electron properties and the...

Self Consistent Random Phase Approximation and the restoration of symmetries within the three-level Lipkin model

We show that it is possible to restore the symmetry associated with the Goldstone mode within the Self Consistent Random Phase Approximation (SCRPA) applied to the three-level Lipkin model. We determine one and two-body densities as very convergent expansions in terms of the generators of the RPA basis. We show that SCRPA excitations correspond to the heads of some rotational bands in the exact...
