Recursive computation of matrix elements in the numerical renormalization group
Thenumerical renormalization group is an efficientmethod to diagonalizemodelHamiltonians describing correlated orbitals coupled to conduction states. While only the resulting eigenvalues are needed to calculate the thermodynamical properties for such models, matrix elements of Fermi operators must be evaluated before excitation and transport properties can be computed. The traditional procedure...
متن کاملS - Matrix Elements in Euclidean Lattice Theories
Expressions for S-matrix elements involving Euclidean expectations are presented.
متن کاملThe Action Principle in Epstein Glaser Renormalization and Renormalization of the S-Matrix of Φ-Theory
A formula describing finite renormalizations is derived in the Epstein-Glaser formalism and an explicit calculation of finite counterterms in Φ-theory is performed. The Zimmermann identities and the action principle for changes of parameters and external fields are presented.
متن کاملDensity Matrix Renormalization
The Density Matrix Renormalization Group (DMRG) has become a powerful numerical method that can be applied to low-dimensional strongly correlated fermionic and bosonic systems. It allows for a very precise calculation of static, dynamic and thermodynamic properties. Its field of applicability has now extended beyond Condensed Matter, and is successfully used in Statistical Mechanics and High En...
