Nucleon-nucleon scattering with the Complex Scaling Method and realistic interactions

G. Papadimitriou, J. P. Vary

We demonstrate the validity of the complex scaling method for realistic strong, non-local, nucleon- nucleon interactions by comparing the deuteron bound state and nucleon-nucleon s…

Advances in Basis Light-front Quantization

Xingbo Zhao

Basis Light-front Quantization has been developed as a first-principles nonperturbative approach to quantum field theory. In this article we report our recent progress on the appli…

Non-Perturbative Calculation of the Scalar Yukawa Theory in Four-Body Truncation

Yang Li, V. A. Karmanov, P. Maris +1

The quenched scalar Yukawa theory is solved in the light-front Tamm-Dancoff approach including up to four constituents (one scalar nucleon, three scalar pions). The Fock sector dep…

Low-energy neutron-deuteron reactions with N3LO chiral forces

J. Golak, R. Skibinski, K. Topolnicki +16

We solve three-nucleon Faddeev equations with nucleon-nucleon and three-nucleon forces derived consistently in the framework of chiral perturbation theory at next-to-next-to-next-t…

Halo nuclei 6He and 8He with the Coulomb-Sturmian basis

M. A. Caprio, P. Maris, J. P. Vary

The rapid Gaussian falloff of the oscillator functions at large radius makes them poorly suited for the description of the asymptotic properties of the nuclear wave function, a pro…

Emergence of rotational bands in ab initio no-core configuration interaction calculations of the Be isotopes

P. Maris, M. A. Caprio, J. P. Vary

The emergence of rotational bands is observed in no-core configuration interaction (NCCI) calculations for the Be isotopes (7<=A<=12), as evidenced by rotational patterns for excit…

On the role of magnetic field in photon excess in heavy ion collisions

Kirill Tuchin

Synchrotron photon spectrum in heavy-ion collisions is computed taking into account the spatial and temporal structure of magnetic field. It is found that a significant fraction of…

Applications of Basis Light-Front Quantization to QED

James P. Vary, Xingbo Zhao, Anton Ilderton +3

Hamiltonian light-front quantum field theory provides a framework for calculating both static and dynamic properties of strongly interacting relativistic systems. Invariant masses,…

Nuclear matter with JISP16 NN interaction

A. M. Shirokov, A. G. Negoita, J. P. Vary +4

Saturation properties of the JISP16 NN interaction are studied in symmetric nuclear matter calculations, with special attention paid to the convergence properties with respect to t…

Ab Initio study of neutron drops with chiral Hamiltonians

H. D. Potter, S. Fischer, P. Maris +5

We report ab initio calculations for neutron drops in a 10 MeV external harmonic-oscillator trap using chiral nucleon-nucleon plus three-nucleon interactions. We present total bind…

C properties with evolved chiral three-nucleon interactions

P. Maris, J. P. Vary, A. Calci +3

We investigate selected static and transition properties of C using ab initio No-Core Shell Model (NCSM) methods with chiral two- and three-nucleon interactions. We adopt th…

Electron g-2 in Light-Front Quantization

Xingbo Zhao, Heli Honkanen, Pieter Maris +2

Basis Light-front Quantization has been proposed as a nonperturbative framework for solving quantum field theory. We apply this approach to Quantum Electrodynamics and explicitly s…
