Geodesic compatibility: Goldfish systems
Worapat Piensuk, Sikarin Yoo-Kong
To capture a multidimensional consistency feature of integrable systems in terms of the geometry, we give a condition called \emph{geodesic compatibility} that implies the existenc…
Integrable Hamiltonian Hierarchies and Lagrangian 1-Forms
Chisanupong Puttarprom, Worapat Piensuk, Sikarin Yoo-Kong
We present further developments on the Lagrangian 1-form description for one-dimensional integrable systems in both discrete and continuous levels. A key feature of integrability i…
Hamiltonian Zoo for systems with one degree of freedom
Saksilpa Srisukson, Kittapat Ratanaphupha, Sikarin Yoo-Kong
We present alternative explicit forms of the standard Hamiltonian for systems with one degree of freedom. This new class of infinite Hamiltonians is called Newton-equivalent Hamilt…
Ground state entanglement entropy for discrete-time two coupled harmonic oscillators
Watcharanon Kantayasakun, Sikarin Yoo-Kong, Tanapat Deesuwan +2
The ground state entanglement of the system, both in discrete-time and continuous-time cases, is quantified through the linear entropy. The result shows that the entanglement incre…
