The Influence of the Symmetry of Identical Particles on Flight Times

open access: yesEntropy, 2021
In this work, our purpose is to show how the symmetry of identical particles can influence the time evolution of free particles in the nonrelativistic and relativistic domains as well as in the scattering by a potential δ-barrier.

Momentum-Space Decoherence of Distinguishable and Identical Particles in the Caldeira–Leggett Formalism

open access: yesEntropy, 2021
In this work, momentum-space decoherence using minimum and nonminimum-uncertainty-product (stretched) Gaussian wave packets in the framework of Caldeira–Leggett formalism and under the presence of a linear potential is studied. As a dimensionless measure

Quantum simulation of bosons with the contracted quantum eigensolver

open access: yesNew Journal of Physics, 2023
Quantum computers are promising tools for simulating many-body quantum systems due to their potential scaling advantage over classical computers. While significant effort has been expended on many-fermion systems, here we simulate a model entangled many ...

An exact one-particle theory of bosonic excitations: from a generalized Hohenberg–Kohn theorem to convexified N-representability

open access: yesNew Journal of Physics, 2023
Motivated by the Penrose–Onsager criterion for Bose–Einstein condensation we propose a functional theory for targeting low-lying excitation energies of bosonic quantum systems through the one-particle picture.

Many-body interference in bosonic dynamics

open access: yesNew Journal of Physics, 2020
We develop a framework to systematically investigate the influence of many-particle interference on the dynamics of generic—possibly interacting—bosonic systems.

Quantum statistics: the indistinguishability principle and the permutation group theory [PDF]

open access: yesRevista Brasileira de Ensino de Física, 2007
About two decades ago we have shown mathematically that besides bosons and fermions, it could exist a third kind of particles in nature that was named gentileons. Our results have been obtained rigorously within the framework of quantum mechanics and the

Spin–orbit coupling in the presence of strong atomic correlations

open access: yesNew Journal of Physics, 2020
We explore the influence of contact interactions on a synthetically spin–orbit coupled system of two ultracold trapped atoms. Even though the system we consider is bosonic, we show that a regime exists in which the competition between the contact and ...

Search for high-mass Wγ and Zγ resonances using hadronic W/Z boson decays from 139 fb −1 of pp collisions at s $$ \sqrt{s} $$ = 13 TeV with the ATLAS detector

open access: yesJournal of High Energy Physics, 2023
A search for high-mass charged and neutral bosons decaying to Wγ and Zγ final states is presented in this paper. The analysis uses a data sample of s $$ \sqrt{s} $$ = 13 TeV proton-proton collisions with an integrated luminosity of 139 fb −1 collected by

A shell of bosons in spherically symmetric spacetimes

open access: yesPhysics Letters B, 2021
The thermodynamic properties of a shell of bosons with the inner surface locating at Planck length away from the horizon of Schwarzschild black holes by using statistical mechanics are studied. The covariant partition function of bosons is obtained, from

Random k-Body Ensembles for Chaos and Thermalization in Isolated Systems

open access: yesEntropy, 2018
Embedded ensembles or random matrix ensembles generated by k-body interactions acting in many-particle spaces are now well established to be paradigmatic models for many-body chaos and thermalization in isolated finite quantum (fermion or boson) systems.
