Advancing Machine Learning Applications in Quantum Few-Body Systems
Jin Ziqi, Paolo Recchia, Mario Gattobigio
This paper presents a general neural network framework for solving quantum few-body systems, extending prior methods to handle diverse particle masses, interaction types, and syste…
The and correlation functions
E. Garrido, A. Kievsky, M. Gattobigio +5
In this work we present the study of and scattering processes using femtoscopic correlation functions. This observable has been recently used to access the low-energy in…
The correlation function with a screened Coulomb potential
A. Kievsky, E. Garrido, M. Viviani +1
The correlation function is a useful tool to study the interaction between hadrons. The theoretical description of this observable requires the knowledge of the scattering wave fun…
Universal tetramer limit-cycle at the unitarity limit
Tobias Frederico, Mario Gattobigio
We demonstrate that a four-boson limit-cycle independent of the Efimov one appears in Hamiltonian systems at the unitary limit. The model interaction contains two-, three- and four…
Subleading contributions to -boson systems inside the universal window
Paolo Recchia, Alejandro Kievsky, Luca Girlanda +1
We study bosonic systems in the regime in which the two-body system has a shallow bound state or, equivalently, a large value of the two-body scattering length. Using the effective…
A Many-Body Density Energy Functional
A. Kievsky, G. Orlandini, M. Gattobigio
The Hohenberg-Kohn theorem and the Kohn-Sham equations, which are at the basis of the Density Functional Theory, are reformulated in terms of a particular many-body density, which…
