The families of Hamiltonians sharing common symmetry structure
Cezary Gonera, Joanna Gonera, Artur Jasiński +1
We describe a general procedure which allows to construct, starting from a given Hamiltonian, the whole family of new ones sharing the same set of unparameterized trajectories in p…

Symmetries and integrals of motion of a superintegrable deformed oscillator
Joanna Gonera, Artur Jasinski, Piotr Kosinski
The symmetry structure of twodimensional nonlinear isotropic oscillator, introduced in Physica D237 (2008) 505, is discussed. It is shown that it possesses three independent integr…

Machine-learning-corrected quantum dynamics calculations
A. Jasinski, J. Montaner, R. C. Forrey +6
Quantum scattering calculations for all but low-dimensional systems at low energies must rely on approximations. All approximations introduce errors. The impact of these errors is…
