Constrained correlated-Gaussians for hyperspherical calculations
Y. Suzuki, K. Varga
We formulate a hyperspherical approach within standard configuration interaction calculations aiming at a description of large-scale dynamics of -particle system. The channel wa…
Quantum Monte Carlo calculations of nuclei
Steven C. Pieper, K. Varga, R. B. Wiringa
We report on quantum Monte Carlo calculations of the ground and low-lying excited states of nuclei using realistic Hamiltonians containing the Argonne two-nucleon…
Monte Carlo integration in Glauber model analysis of reactions of halo nuclei
Kalman Varga, Steven C. Pieper, Y. Suzuki +1
Reaction and elastic differential cross sections are calculated for light nuclei in the framework of the Glauber theory. The optical phase-shift function is evaluated by Monte Carl…
Borromean Binding of Three or Four Bosons
Steven Moszkowski, Sonia Fleck, Ali Krikeb +3
We estimate the ratio of the critical coupling constants and which are required to achieve binding of 2 or 3 bosons, respectively, with a short-rang…
Local realizations of contact interactions in two- and three-body problems
A. T. Kruppa, K. Varga, J. Revai
Mathematically rigorous theory of the two-body contact interaction in three dimension is reviewed. Local potential realizations of this proper contact interaction are given in term…
Exploration of resonances by analytic continuation in the coupling constant
N. Tanaka, Y. Suzuki, K. Varga
The energy and the width of resonance states are determined by analytic continuation of bound-state energies as a function of the coupling constant (potential strength). The advant…
New representation of orbital motion with arbitrary angular momenta
Y. Suzuki, J. Usukura, K. Varga
A new formulation is presented for a variational calculation of -body systems on a correlated Gaussian basis with arbitrary angular momenta. The rotational motion of the system…
Stochastic variational method with noncentral forces
K. Varga, Y. Ohbayasi, Y. Suzuki
This paper extends the application of the stochastic variational method to noncentral interactions. Several examples are presented for three- and four-nucleon systems with realisti…
Occupation probability of harmonic-oscillator quanta for microscopic cluster-model wave functions
Y. Suzuki, K. Arai, Y. Ogawa +1
We present a new and simple method of calculating the occupation probability of the number of total harmonic-oscillator quanta for a microscopic cluster-model wave function. Exampl…
A combined mathematica--fortran program package for analytical calculation of the matrix elements of the microscopic cluster model
K. Varga
We present a computer code that analytically evaluates the matrix elements of the microscopic nuclear Hamiltonian and unity operator between Slater determinants of displaced gaussi…
Two-body matrix elements of Pauli-projected excentric single-particle orbits
K. Varga
We present explicit analytical formulae for two-body matrix elements between Pauli-projected single-particle orbits generated by gaussians shifted from the centre of a nuclear core…
