Abstract: Abstract We consider a typical many body problem. In particular, we study an exactly solvable fermion system. We apply to it recently developed statistical quantifiers like the statistical complexity C and the disequilibrium D .… read more here.

Abstract: I determine the intrinsic Hamiltonian of the relative motion of the constituent fermions of bosonic composites in superfluid fermion systems, assuming the effective fermion-fermion potential to be a sum of separable terms. The derivation is… read more here.

DOI: 10.1103/physrevc.107.044318
Abstract: There is no unique and widely accepted definition of the complexity measure (CM) of a many-fermion wave function in the presence of interactions. The simplest many-fermion wave function is a Slater determinant. In shell-model or… read more here.
