Limits of the Formal Integrals of Motion
George Contopoulos, Athanasios C. Tzemos, Foivos Zanias
We consider a formal (approximate) integral of motion in Hamiltonians of the form generalizing previous c…
Bohmian Chaos and Entanglement in a Two-Qubit System
Athanasios C. Tzemos, George Contopoulos, Foivos Zanias
We study in detail the critical points of Bohmian flow, both in the inertial frame of reference (Y-points) and in the frames centered at the moving nodal points of the guiding wave…
Orbits in the integrable Hénon-Heiles systems
Athanasios C. Tzemos, George Contopoulos, Foivos Zanias
We study in detail the form of the orbits in integrable generalized Hénon-Heiles systems with Hamiltonians of the form $H = \frac{1}{2}(\dot{x}^2 + Ax^2 + \dot{y}^2 + By^2) + ε(x…
Integrals and chaos in generalized Hénon-Heiles Hamiltonians
G. Contopoulos, A. C. Tzemos, F. Zanias
We study the approximate (formal) integrals of motion in the Hamiltonian which i…
