WebJun 30, 2024 · The Hamiltonian is H(x, p, t) = ∑ i ˙qi∂L ∂˙qi − L = p2 2m + 1 2k(x − v0t)2 The Hamiltonian is the sum of the kinetic and potential energies and equals the total energy of the system, but it is not conserved since L and H are both explicit functions of time, that is dH dt = ∂H ∂t = − ∂L ∂t ≠ 0. A Hamiltonian system is a dynamical system governed by Hamilton's equations. In physics, this dynamical system describes the evolution of a physical system such as a planetary system or an electron in an electromagnetic field. These systems can be studied in both Hamiltonian mechanics and dynamical systems … See more Informally, a Hamiltonian system is a mathematical formalism developed by Hamilton to describe the evolution equations of a physical system.

Web1 day ago · A method for the nonintrusive and structure-preserving model reduction of canonical and noncanonical Hamiltonian systems is presented. Based on the idea of operator inference, this technique is provably convergent and reduces to a straightforward linear solve given snapshot data and gray-box knowledge of the system Hamiltonian.
