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…
Improving the convergence of an iterative algorithm for solving arbitrary linear equation systems using classical or quantum binary optimization
Erick R. Castro, Eldues O. Martins, Roberto S. Sarthour +2
Recent advancements in quantum computing and quantum-inspired algorithms have sparked renewed interest in binary optimization. These hardware and software innovations promise to re…
Interacting bosons in a triple well: Preface of many-body quantum chaos
Karin Wittmann W., E. R. Castro, Angela Foerster +1
Systems of interacting bosons in triple-well potentials are of significant theoretical and experimental interest. They are explored in contexts that range from quantum phase transi…
Quantum-classical correspondence of a system of interacting bosons in a triple-well potential
E. R. Castro, Jorge Chavez-Carlos, I. Roditi +2
We study the quantum-classical correspondence of an experimentally accessible system of interacting bosons in a tilted triple-well potential. With the semiclassical analysis, we ge…
An exact solution method for the enumeration of connected Feynman diagrams
Erick Ramon Castro, Itzhak Roditi
We completely generalize previous results related to the counting of connected Feynman diagrams. We use a generating function approach, which encodes the Wick contraction combinato…
