Unitary Correlations and the Fejér Kernel
 Mathematical Physics, Analysis, and Geometry
, 2002
"... Let M be a unitary matrix with eigenvalues t j , and let f be a function on the unit circle. Define X f (M) = P f(t j ). We derive exact and asymptotic formulae for the covariance of X f and X g with respect to the measures j(M)j 2 dM where dM is Haar measure and an irreducible character. The ..."

A Unitary Correlation Operator Method
 Nucl. Phys. A632
, 1998
"... The short range repulsion between nucleons is treated by a unitary correlation operator which shifts the nucleons away from each other whenever their uncorrelated positions are within the repulsive core. By formulating the correlation as a transformation of the relative distance between particle pai ..."

Unitarycorrelationoperator method for Λ hypernuclei
, 1999
"... The unitarycorrelationoperator method (UCOM) is formulated for the description of lambda hypernuclei. The method is applied to 17 Λ O. A lambdanucleon effective interaction is derived, taking the coupling of the sigmanucleon channel into account. The lambda singleparticle energies are calculate ..."

Nuclear Structure in the Framework of the Unitary Correlation Operator Method
"... Correlations play a crucial role in the nuclear manybody problem. We give an overview of recent developments in nuclear structure theory aiming at the description of these interactioninduced correlations by unitary transformations. We focus on the Unitary Correlation Operator Method (UCOM), which ..."

Tensor correlations in the unitary correlation operator method, Nuc. Phys. A713
, 2003
"... We present a unitary correlation operator that explicitly induces into shell model type manybody states short ranged twobody correlations caused by the strong repulsive core and the pronounced tensor part of the nucleonnucleon interaction. Alternatively an effective Hamiltonian can be defined by ..."

SELFCONSISTENT DESCRIPTION OF COLLECTIVE EXCITATIONS IN THE UNITARY CORRELATION OPERATOR METHOD
, 2005
"... The fully selfconsistent Random Phase Approximation (RPA) is constructed within the Unitary Correlation Operator Method (UCOM), which describes the dominant interactioninduced shortrange central and tensor correlations by a unitary transformation. Based on the correlated Argonne V18 interaction, ..."

The spandrels of San Marco and the Panglossian paradigm: a critique of the adaptationist programme.
 Proceedings of the Royal Society of London Series B, Biological Sciences
, 1979
"... An adaptationist programme has dominated evolutionary thought in England and the United States during the past 40 years. It is based on faith in the power of natural selection as an optimizing agent. It proceeds by breaking an organism into unitary 'traits' and proposing an adaptive story ..."
