Subtle Nuances between Quantum and Classical regimes
Karin Wittmann Wilsmann, Erick R. Castro, Itzhak Roditi +2
This study explores the semiclassical limit of an integrable-chaotic bosonic many-body quantum system, providing nuanced insights into its behavior. We examine classical-quantum co…
From integrability to chaos: the quantum-classical correspondence in a triple well bosonic model
Erick R. Castro, Karin Wittmann W., Jorge Chávez-Carlos +3
In this work, we investigate the semiclassical limit of a simple bosonic quantum many-body system exhibiting both integrable and chaotic behavior. A classical Hamiltonian is derive…
Maximal violation of the Bell-Clauser-Horne-Shimony-Holt inequality via bumpified Haar wavelets
David Dudal, Philipe De Fabritiis, Marcelo S. Guimaraes +2
We devise a general setup to investigate the violation of the Bell-CHSH inequality in the vacuum state in the context of Quantum Field Theory. We test the method with massless spin…
Probing Mermin's inequalities violations through pseudospin operators
Philipe De Fabritiis, Itzhak Roditi, Silvio P. Sorella
The violation of Mermin's inequalities is analyzed by making use of two different Bell setups built with pseudospin operators. Employing entangled states defined by means of squeez…
Mermin's inequalities in Quantum Field Theory
Philipe De Fabritiis, Itzhak Roditi, Silvio Paolo Sorella
A relativistic Quantum Field Theory framework is devised for Mermin's inequalities. By employing smeared Dirac spinor fields, we are able to introduce unitary operators which creat…
Implementation of a two-stroke quantum heat engine with a collisional model
Filipe V. Melo, Nahum Sá, Ithzak Roditi +4
We put forth a quantum simulation of a stroboscopic two-stroke thermal engine in the IBMQ processor. The system consists of a quantum spin chain connected to two baths at their bou…
