Linear response strength functions with iterative Arnoldi diagonalization
, 2009 We report on an implementation of a new method to calculate RPA strength functions with iterative non-hermitian Arnoldi diagonalization method, which does not explicitly calculate and store the RPA matrix.

Extending the random-phase approximation for electronic correlation energies: The renormalized adiabatic local density approximation [PDF]
, 2012 The adiabatic connection fluctuation-dissipation theorem with the random phase approximation (RPA) has recently been applied with success to obtain correlation energies of a variety of chemical and solid state systems.

Description of thermal entanglement with the static path plus random-phase approximation
, 2010 We discuss the application of the static path plus random phase approximation (SPA+RPA) and the ensuing mean field+RPA treatment to the evaluation of entanglement in composite quantum systems at finite temperature.

Electric Field‐Induced Hole‐ and Electron‐Type Flat Bands in Twisted Double Bilayer Graphene
Advanced Electronic Materials, EarlyView.The electronic structure of twisted double bilayer graphene is visualized using angle‐resolved photoemission spectroscopy with micrometer spatial resolution at twists of 3.1∘$^\circ$ and 6.0∘$^\circ$ as a function of gate voltage. Tunable hybridization effects and flat band formation occurs between valence and conduction band states due to a finite ...

Comparison of Gamow-Teller strengths in the random phase approximation
, 2013 The Gamow-Teller response is astrophysically important for a number of nuclides, particularly around iron. The random phase approximation (RPA) is an efficient way to generate strength distributions.

American Journal of Medical Genetics Part A, EarlyView.ABSTRACT Carpenter syndrome type 2 (CRPT2) is a rare autosomal recessive disease mainly characterized by craniosynostosis and polysyndactyly. CRPT2 is the rarer subtype of Carpenter syndrome (CRPTS) and is caused by biallelic variants in the multiple epidermal growth factor‐like domains 8 gene (MEGF8).

RPA approach to supersolidity [PDF]
EPL (Europhysics Letters), 2009 We investigate the newly discovered supersolid phase by solving in random phase approximation the anisotropic Heisenberg model of the hard-core boson 4He lattice. We include nearest- and next-nearest-neighbor interactions and calculate exactly all pair correlation functions in a cumulant expansion scheme.
