Time-dependent local-to-normal mode transition in triatomic molecules
Hans Cruz, Marisol Bermúdez-Montaña, Renato Lemus
Time-evolution of the vibrational states of two interacting harmonic oscillators in the local mode scheme is presented. A local-to-normal mode transition (LNT) is identified and st…
Contact Hamiltonian Mechanics
Alessandro Bravetti, Hans Cruz, Diego Tapias
In this work we introduce contact Hamiltonian mechanics, an extension of symplectic Hamiltonian mechanics, and show that it is a natural candidate for a geometric description of no…
Time-evolution of quantum systems via a complex nonlinear Riccati equation II. Dissipative systems
Hans Cruz, Dieter Schuch, Octavio Castanos +1
In our former contribution [Ann. Phys. 360 (2015) 44], we have shown the sensitivity to the choice of initial conditions in the evolution of Gaussian wave packets via the nonlinear…
