    We study the application of the exact renormalisation group to a many-fermion system with a short-range attractive force. We introduce a boson field to describe pairing effects, and take a simple ansatz for the effective action. We derive a set of approximate flow equations for the effective coupling including boson and fermionic by: Description; Chapters; Supplementary; Systems of strongly correlated electrons are at the heart of recent developments in condensed matter theory. They have applications to phenomena like high-T c superconductivity and the fractional quantum hall ical solutions to such models, though mainly limited to one spatial dimension, provide a complete and unambiguous picture of the.

    The effects of possible superfluidity on the cranking moment of a lange many-fermion system moving under pericdic boundary conditions were investigated within the framework of the theory of superconductivity recently formulated by Bogolyubov. The Hamiltonian was initially subjected to . The Fermi hole curvature C(r,s) is defined as the Laplacian of the parallel‐spin pair distribution, evaluated at zero separation r ’ =r for a pair of Fermions in a many‐Fermion system. It has been used by a number of authors to discuss electron localization, properties of the exchange and correlation hole, and exchange and correlation energies of inhomogeneous electron by:

We have developed a Quantum Monte Carlo optimization (QMCO) method for many fermion systems. The ground state wave function is written as a linear combination of the basis states generated using the auxiliary field method The bases are chosen with weights that are determined by diagonalizing the Hamiltonian to lower the ground state energy.

The QMCO method is free from a difficulty originating Author: Takashi Yanagisawa. Abstract. We characterize and classify quantum correlations in two-fermion systems having 2 K single-particle states.

For pure states we introduce the Slater decomposition and rank (in analogy to Schmidt decomposition and rank), i.e. we decompose the state into a combination of elementary Slater determinants formed by pairs of mutually orthogonal single-particle by: the correlation function decays asymptotically as C (R) / R xej Rj=˘ () where xis some characteristic power, and ˘is called the \correlation length."
