Probing ferromagnetic order in few-fermion correlated spin-flip dynamics

open access: yesNew Journal of Physics, 2019
We unravel the dynamical stability of a fully polarized one-dimensional ultracold few-fermion spin-1/2 gas subjected to inhomogeneous driving of the itinerant spins.

Rescattering in Meson Photoproduction off Few Body Systems

open access: yes, 2006
Exclusive reactions induced at high momentum transfer in few body systems provide us with an original way to study the production and propagation of hadrons in cold nuclear matter.

A coordinate Bethe ansatz approach to the calculation of equilibrium and nonequilibrium correlations of the one-dimensional Bose gas

open access: yesNew Journal of Physics, 2016
We use the coordinate Bethe ansatz to exactly calculate matrix elements between eigenstates of the Lieb–Liniger model of one-dimensional bosons interacting via a two-body delta-potential.

Detecting few-body quantum chaos: out-of-time ordered correlators at saturation

open access: yesJournal of High Energy Physics, 2022
We study numerically and analytically the time dependence and saturation of out-of-time ordered correlators (OTOC) in chaotic few-body quantum-mechanical systems: quantum Henon-Heiles system (weakly chaotic), BMN matrix quantum mechanics (strongly ...

Signatures of few-body resonances in finite volume [PDF]

open access: yes, 2018
We study systems of bosons and fermions in finite periodic boxes and show how the existence and properties of few-body resonances can be extracted from studying the volume dependence of the calculated energy spectra.

Few-Body Universality in Halo Nuclei

open access: yesEPJ Web of Conferences, 2016
Few-body systems with resonant S-wave interactions show universal properties which are independent of the interaction at short distances. These properties include a geometric spectrum of three- and higher-body bound states and universal correlations ...

Threshold behavior of bosonic two-dimensional few-body systems

open access: yes, 2005
Bosonic two-dimensional self-bound clusters consisting of $N$ atoms interacting through additive van der Waals potentials become unbound at a critical mass m*(N); m*(N) has been predicted to be independent of the size of the system.

New Insight of Time-transformed Symplectic Integrator. I. Hybrid Methods for Hierarchical Triples

open access: yesThe Astrophysical Journal
Accurate N -body simulations of multiple systems such as binaries and triples are essential for understanding the formation and evolution of interacting binaries and binary mergers, including gravitational wave sources, blue stragglers, and X-ray ...

Implementing PCAC in Nonperturbative Models of Pion Production [PDF]

open access: yes, 1999
Traditional few-body descriptions of pion production use integral equations to sum the strong interactions nonperturbatively. Although much physics is thereby included, there has not been a practical way of incorporating the constraints of chiral ...
