Coherent photoproduction of a π0-meson on a tensor-polarized deuteron at large momentum transfer

open access: yesResults in Physics, 2022
Measured values of the tensor analyzing power T20for the coherent photoproduction of a π0-meson on a deuteron are analyzed in the region of large momentum transfer.

Universal few-body physics in a harmonic trap [PDF]

open access: yes, 2011
Few-body systems with resonant short-range interactions display universal properties that do not depend on the details of their structure or their interactions at short distances.

Fluctuations of work in realistic equilibrium states of quantum systems with conserved quantities

open access: yesSciPost Physics Proceedings, 2020
The out-of-equilibrium dynamics of quantum systems is one of the most fascinating problems in physics, with outstanding open questions on issues such as relaxation to equilibrium.

Ordering in one-dimensional few-fermion clusters with repulsive interactions

open access: yesNew Journal of Physics, 2016
By using a diffusion Monte Carlo (DMC) technique, we studied the behaviour of a mixture of spin-up and spin-down cold fermionic atoms confined in one-dimensional harmonic potentials.

Photoproduction of π0-Mesons from the Nucleon and Deuteron

open access: yesMakara Journal of Science, 2016
The photoproduction of π0-mesons from the nucleon and deuteron has been studied for incidents of photon energies up to 1.5 GeV. By using the MAID-2007 model for the process on the nucleon, we predict results for the unpolarized and helicity-dependent ...

Spectral properties and breathing dynamics of a few-body Bose–Bose mixture in a 1D harmonic trap

open access: yesNew Journal of Physics, 2018
We investigate a few-body mixture of two bosonic components, each consisting of two particles confined in a quasi one-dimensional harmonic trap. By means of exact diagonalization with a correlated basis approach we obtain the low-energy spectrum and ...

Few-body calculations of η-nuclear quasibound states

open access: yesPhysics Letters B, 2015
We report on precise hyperspherical-basis calculations of ηNN and ηNNN quasibound states, using energy dependent ηN interaction potentials derived from coupled-channel models of the S11 N⁎(1535) nucleon resonance.

Resonances in Few-body Systems [PDF]

open access: yesAustralian Journal of Physics, 1991
I will show how the resonance poles of the scattering amplitude correspond to eigenstates of the Hamiltonian that is analytically continued into the complex r-space via the dilatation group transformation, and how the corresponding eigenstates satisfy a modified form of the orthogonality condition.

Quantum point spread function for imaging trapped few-body systems with a quantum gas microscope

open access: yesNew Journal of Physics, 2019
Quantum gas microscopes, which image the atomic occupations in an optical lattice, have opened a new avenue to the exploration of many-body lattice systems.

Lattice simulations for few- and many-body systems

open access: yes, 2008
We review the recent literature on lattice simulations for few- and many-body systems. We focus on methods and results that combine the framework of effective field theory with computational lattice methods.
